Average length body 2.5-3 m.
Life span in captivity for up to 30 years.
Features of behavior- adults are docile, rarely express aggression. Young snakes can make trial lunges and are occasionally aggressive. They prefer a habitat with a constant source of fresh water. Excellent tree climb. Depending on the biotope, it leads a semi-woody and nasal way of life. Active at twilight and night hours. During the day he hides in shelters - crevices, driftwood, caves, hollows. Swims well, does not dive.
Gender differences males and females do not exist. Comparative examination of males shows a longer tail, with a thickening at the cloaca. In females, the tail is somewhat shorter and without thickening. Both sexes have claw-like rudiments at the anus, which are more powerful and longer in males. Females have a more powerful constitution and larger size.
Puberty at 2.5-4 years old. Ovoviviparous species. Pregnancy lasts 5 to 7 months. The female gives birth to 20 to 50 pups. The first molt is one week after birth.
Content. Terrarium horizontal type ... The size for small species is 45-45 cm, for larger representatives with an area of 70-45 cm. Temperature Range in the daytime 24-28, at the warming point 33-35оС, at night not lower than 24оС. Humidity supported by about 50-80%. A permanent reservoir is needed in which the snake can easily fit completely. Priming not required. Suitable substrates are paper, napkins, rubber mats, and bark. Shelter placed if necessary, spacious and twilight. It is placed in a cool corner. Daylight hours 12 hours. You need to install ultraviolet lamps with a power of 5-8% UVB.
Feeding up to a year, it is possible every 5-7 days, after a year, once every 10-14 days. Fodder rodents and small birds are used as feed. The size of the prey varies depending on the size of the snake itself - mice-pubescent, newborn rats for small ones, mice, rats, mastomus, gerbils, guinea pigs for large individuals.
The boa constrictor is a nocturnal and twilight animal (active at dawn and dusk). V northern and in the southern regions, boas hibernate for several weeks to wait out cold or dry seasons. Boas living in rainforests with high humidity are active throughout the year.
In the first year of life, a boa constrictor will grow from 35-55 cm by 300%, reaching a length of 1.5-1.8 m.In the second year, a boa constrictor will grow by another 0.9-1.2 m.After the second year, the growth of a boa constrictor slows down ... Females give birth to 10-60 boa constrictors after a gestational period of 4-10 months (depending on temperature and other factors). Unlike others large snakes, the female boa constrictor does not give birth every year.
At the time of buying boa constrictor choose a reptile with clear, clean skin. The boa constrictor should be rounded, the anal area holes must be clean, eyes clear. When a healthy boa constrictor is picked up, he begins to actively move his tongue. Like pythons, boas have anal spurs - claws located on two parties anal opening, which are vestigial remnants of the hind legs. In males, anal spurs are longer than in females. Females and males differ slightly in behavior and character. From of all boas, the boa constrictor is the least aggressive.
To keep the boa constrictor, choose a terrarium specially designed for snakes, with a lid that closes from above. Snakes often run away from terrariums, especially boas, as they are strong. When your boa constrictor turns more than two years old, it will need to be moved to another terrarium, which you can build yourself from wood and glass (plexiglass), or you can buy a special terrarium for large reptiles. Big snakes need a big terrarium!
Paper towels are used as a substrate first, as they are easy to remove and replace with new ones when they get dirty. On paper, it is easy to notice the presence of ticks (if they appear) and control the quality of the boa's feces. As soon as the boa is older, you can use Astroturf decorative cover or a cover made of split cypress or spruce bark instead of paper. Pine and cedar sawdust cannot be used, as they stick to food, can get into the mouth and respiratory tract of the boa constrictor, thereby creating many health problems. All wet and dirty parts of the substrate should be removed as quickly as possible to prevent height fungi and bacteria.
Boa constrictor
In the terrarium, the boa constrictor should have secret places where he will hide. For these purposes, you can use logs, empty cardboard boxes, an opaque plastic container, etc., all that is easy to replace with a new one or easy to clean. Most boas love to hang from branches, so be sure to place sturdy branches in the enclosure that can support the weight of the boa (the branches must be sanded and decontaminated!). If you are using stones and bricks to build a cave, make sure it is firmly held together, as boas are very strong and can easily destroy such construction and thereby cause yourself various injuries.
The air temperature in the terrarium should be 28-32'C, with a heating area in which the temperature reaches 32-35'C. At night, the temperature should drop to 26-30'C. The terrarium can be heated with a heating pad, which is placed under the half of the terrarium. To provide additional temperature, some owners use bulbs that are placed on top (the boa constrictor should not touch them, otherwise he will get burned!). All snakes are very susceptible to burns, for the same reason hot stones should not be used to heat the enclosure. To measure temperature, you need two thermometers: the first arrange at a height of 2.5 cm above the substrate (cool half of the terrarium), and the second at the same height, but in the warm half. It is advisable to place the third thermometer- at the top of the heating zone. Once your boa constrictor has grown, it is best to use a thermostat to control the temperature.
Full spectrum UV lamps can be used to illuminate the terrarium.
After buying a young boa constrictor, give him two weeks to acclimatize to a new home. During this time, give him one 10-day-old rat (the rodent must be dead). Smaller boas are given small mice, large snakes can eat large rats. The basic rule in feeding boas: the size of the food should not be wider than the widest part of the snake. If a boa constrictor is fed too large prey, it will regurgitate food after a few days.
In captivity, snakes are often overfed, especially pythons and boas, as they do not have the ability to move enough and spend calories.
There should always be fresh water inside the terrarium, the boa constrictor will drink and swim in it. The water needs to be changed frequently as it gets dirty. Before molting, you can offer the boa constrictor a warm bath.
After buying a young boa constrictor, start accustoming him to yourself. Take the boa constrictor in your hands carefully, at first it can run away from you and hiss. Be persistent and gentle. Daily contact with a boa constrictor will establish a relationship of trust between you and the snake. When communicating with a boa constrictor, it is not advisable to make sudden movements. If the snake is wrapped around your arm or neck, take it by the tail and gently begin to unwind it (do not try to unwind the snake from your head, as the snake may be stronger than you).
There should always be ambulance items in the house that will be useful in various situations: nolvasan (for disinfecting the substrate, objects, water dishes, etc.), betadine (treatment of wounds and scratches), sponges, a spare water dish, etc.

Distributed in South and Central America and the Lesser Antilles. There are a large number of subspecies of the common boa constrictor, which differ in a variety of colors. The color is very elegant, bright and contrasting. The darkest, almost black, boas are from Argentina, the reddest, but alas, not the most contrasting ones, from Brazil.
Ground bark
Twilight lifestyle
Boas from Peru are characterized by their ash-gray coloration of the back with bright brown spots and a brownish-red tail. Perhaps the most elegant boas live in southern Mexico and Central America. The color of the latter is the brightest and most contrasting. Despite the bright colors, the boa constrictor perfectly disguises itself as deciduous litter or a scattering of stones.
Distribution area
A large massive snake, it can reach up to 3.5 meters in length. It has a calm phlegmatic character, which allows many reptile lovers to keep this snake at home without much fear.
Two-year-old male from our cattery
They lead both terrestrial and arboreal lifestyles. They climb perfectly on vertical surfaces, which allows them to get food not only on the ground. They swim well, usually located near water bodies. They are fed by various rodents, small mammals, birds, and sometimes reptiles.
The terrarium should be well ventilated. The background temperature should be 25-27 degrees, in the heating zone about 30-35. At night, the temperature can be reduced to 20 degrees. You can create a warm corner for a boa constrictor using a thermal mat, placing it under the terrarium, or an incandescent lamp.
The diet of a boa constrictor in captivity consists of laboratory mice and rats, chickens, and rabbits. A young individual is fed once every 5-7 days, and adult snakes are fed every 7-10 days.
Puberty in captivity in boas occurs at about the 3rd year of life, while the size of the male should be more than 1.5 m, and the female should be 1.8 m. For the reproduction of boas, it is necessary to plant the snakes and arrange for them to winter, reduce the temperature to 15-18 degrees for 2 - 2.5 months. After wintering, the female is placed next to the male, and after long courtship, mating takes place, which lasts several hours. Pregnancy of a female lasts 5-6 months, at the end of this period, she can bring about 40 babies, 45 cm in size. Babies appear in a transparent egg shell, which is immediately torn apart. This type of birth is called ovoviviparous. After a week, the babies molt and begin to hunt on their own. Sometimes babies start feeding on their own only after 1-2 months.
A boa constrictor is a non-venomous snake that belongs to the class reptiles, the squamous squad,.
The Russian word "boa constrictor" arose because of the peculiarity of these reptiles to squeeze the caught prey before swallowing.
Boa constrictor - description, structure, characteristics, photo
Among the boas, there are real giants, for example the common anaconda (lat.Eunectes murinus), reaching a length of more than 10 meters.

The color of boas is similar to the dominant colors in their habitats. It can be gray-brown in species that live on the ground, or bright, sometimes contrasting colors in individuals living in trees or in the forest floor. Some boas have stripes on the body, as well as large or small spots of a round, oblong or diamond-shaped shape and of a wide variety of colors, while the spots can be with or without eyes.
In some species, the skin can shine with a metallic sheen of all colors of the rainbow (for example, in the rainbow boa constrictor). Ground boas have the ability to change color, becoming lighter or darker in color. At night, light-reflecting spots and stripes appear on their bodies, which create a phosphorescent effect.
A characteristic feature of boas, in addition to a flattened head and lack of limbs, is a long muscular body with a rounded cross section. The body of sand boas has a cylindrical shape, it is very dense and with developed muscles.
There is no narrowing in the neck of the sand boas, the tail is blunt and rather short.
The skull of a boa constrictor has a unique structure that allows it to swallow large prey. This is achieved due to the movable connection of the bones of the facial part, as well as the elastic articulation of the parts of the lower jaw with each other. Sharp teeth are located not only on the jaws, but also on the bones that make up the oral apparatus (palatine, pterygoid and intermaxillary). This is due to the fact that boas do not need teeth to grind caught prey, but only to hold or push it deep into the esophagus. On the surface of the head there are large keratinized scutes, grouped in a certain order. Unlike pythons, boas have no supraorbital bones.
Unlike other boas, in Mascarene boas, the maxillary bone is divided into 2 movably interconnected parts: front and back.
The structure of the shortened and flattened head of sand boas is interesting. The wedge-shaped upper jaw, which serves as a burrowing tool, is noticeably pushed forward, so the mouth opening is located below.
The large intermaxillary shield extends onto the upper part of the head, taking on all the load during the movement of the boa in the soil. The front teeth of the upper and lower jaws of the sand boa constrictor are slightly longer than the hind ones.
Unlike other reptiles, which completely lack the belts of the front and hind limbs, the boas have preserved the bones of the pelvis in a rudimentary state. In addition, they retain the remnants of the hind limbs, which appear as paired claws located on either side of the anus.
True, there is an exception here too: for example, in the Mascarene boas, these rudiments are completely absent.

Depending on the size of the boa constrictor, the number of vertebrae that make up the spinal column can range from 141 to 435. A characteristic feature of the structure of the skeleton of snakes is the absence of the sternum, which makes the ribs extremely mobile.
All internal organs of these reptiles have an elongated modified shape due to the general structure of the body. Paired organs are located asymmetrically, and they can be developed unevenly. So, for example, the right lung is much larger in size than the left. In earthen boas (Latin Tropidophiidae), the typical left lung is absent - it has turned into a tracheal (tracheal) lung and is formed by the expansion of the back of the trachea.
The nervous system of boas consists of a small brain and a well-developed spinal cord, which leads to high accuracy and speed of muscle reactions.
In the surrounding space, boas navigate thanks to the organs of smell and touch.
In addition, most of the information is brought by thermosensitive receptors located on the front of the muzzle, and a forked tongue, which transmits information to the brain using special paired organs, which are a kind of chemical analyzers.
The sight of boas is not very sharp. This is in particular due to the fact that eyes with vertical pupils are always covered with a film that has formed from the eyelids that have grown together.
The eyes of the sand boas are small and slightly turned upward - this arrangement is convenient because, even when buried in the ground, the boa constrictor can observe everything that happens on the surface without sticking out his head.
Due to the fact that reptiles lack external auditory openings, and the middle ear is underdeveloped, all snakes hardly distinguish sounds that propagate through the air.
The body of boas from the sides and from above is covered with rhomboid-rounded scales, slightly overlapping each other. Such plates are arranged in longitudinal or diagonal rows. Between the scales of the longitudinal rows, areas of the skin remain, which are collected in small folds, allowing the integument of the body to stretch strongly. The plates located on the belly of reptiles have a transversely elongated shape and are also interconnected by skin areas.
As it grows, the upper teguments age and flake off. A molting process takes place, with the first skin change occurring a few days after the birth of the snake. In healthy boas, the frequency of skin changes does not exceed 4 times a year.

Where do boas live?
Boas live in South and Central America, in Cuba, in the west and south-west of North America, in northern Africa, in South and Central Asia, on the islands of the Malay Archipelago, in Madagascar, Jamaica, Haiti, Trinidad Island, in New Guinea. Some species (rubber snakes and California boas) live in the western states of the United States, as well as in southwestern Canada.
Sand boas, or boas, are widespread in Central and South Asia, as well as in East and North Africa, the Middle East, Asian countries (Iran, Afghanistan, West China, India, Pakistan). Several species live on the territory of Russia (Dagestan, Central and Eastern Transcaucasia) and the CIS countries (Kazakhstan, Mongolia).
Earthen boas inhabit Mexico, South and Central America, and are found in the Bahamas and the Antilles.
Madagascar boas live on the islands of Madagascar and Reunion.
Different types of boas settle in different places: some species prefer dry or humid forests, where they live in the branches of trees or shrubs, others live in deciduous or grassy litter, others choose arid open landscapes as their habitat, others inhabit the waters of rivers or swamps, low-flowing backwaters, branches and lakes, as well as swampy lowlands. Certain varieties of boas are found near human habitation. The snake can be found on plantations and in abandoned houses. By the way, there are even almost domesticated species, for example, an ordinary boa constrictor, which local residents keep in houses or barns so that this snake can catch rats and mice.
Sandy boas have a burrowing way of life to one degree or another: they live in steppes, deserts and semi-deserts, they are found not only in sandy, but also in clay and even gravelly soils, deftly make their way in rather narrow cracks in the soil or under stones, buried in sand and rubble, briskly crawling inside such a shelter.
What does a boa constrictor eat?
The diet of boas is very diverse. It includes not only small or medium-sized animals, birds and amphibians, but also larger representatives of the animal world (,). Small boas feed on possums, waterfowl and other birds and their chicks (, and). Agouti, paki, bakers also become prey for snakes. Cuban boas are also caught. Larger boas, for example, anacondas, can calmly attack capybaras, small crocodiles (caimans), as well as large ones. Also, a boa constrictor can attack a pet that has approached a watering hole:, or a duck.
Having pounced on the victim, the boas twine their rings around it. However, they never break the bones of their victims, so as not to harm their digestive system.
The diet of sand boas includes small rodents (, jerboas, gerbils and), small birds (sparrows, wagtails), as well as lizards (geckos, agamas, roundheads, lizards). Young individuals also feed on darkling beetles. During the hunt, snakes easily crawl into the holes of rodents. The caught prey are held by sand boas with their teeth and are easily killed, twisting around the victim with 2-3 rings of their muscular body.
Scientists who study snakes and have lived for a long time in the Amazon claim that a giant boa constrictor is able to swallow prey that is thicker than its body if the weight of the prey does not exceed 60 kg (wild pigs, small sizes and antelopes). Young individuals of larger animals can also become their victims.
Unlike other snakes, these reptiles are able to hunt in complete darkness. They have special receptors located between the nostrils and eyes that are sensitive to heat. This allows boas, even at a distance, to notice an approaching victim by the heat emanating from its body.
Boas do not eat much. Having absorbed a large piece, they can remain without food from several weeks to several months.
How do boas kill their prey?
Despite the prevailing opinion that the boa constrictor strangles the victim, this belief was not entirely true. Initially, scientists were questioned by the fact that mortal strangulation took at least several minutes, and the victims of the boas died within about 60 seconds. In the mid-90s, American zoologists finally established and substantiated that the victims of boas do not die from a lack of oxygen at all, but from circulatory arrest, which naturally causes cardiac arrest.
For experimental studies, rats were used, in the arteries and veins of which catheters were implanted to measure the pressure of the blood flow and electrodes to monitor the heart rhythms. The rats prepared in this way were given to the boas for execution, but after the snake squeezed the rodent to death, the victim was selected and its thorough analysis was carried out. According to the results of the experiment, zoologists found out: at the time of the deadly snake hugs in rodents, blood pressure dropped sharply and venous pressure also rose rapidly, which led to instant stagnation of blood. Unable to cope with pumping blood, which was under very high pressure, the rats' hearts began to work intermittently and, as a result, stopped.
Types of boas, photos and names
Previously, various types of boas belonged to the following families in the suborder of snakes:
- Mascarene boas, or bolierids (lat.Bolyeriidae),
- Ground boas (lat.Tropidophiidae),
- False-legged, or boa-like snakes (Latin Boidae).
At the moment, the classification has been changed, and, according to the www.itis.gov database, different types of boas belong to the following families:
- Boidae (Gray, 1825)
- Bolyeriidae (Hoffstetter, 1946)
- Calabariidae (Gray, 1858)
- Candoiidae (Pyron, Reynolds and Burbrink, 2014)
- Charinidae (Gray, 1849)
- Erycidae (Bonaparte, 1831)
- Sanziniidae (Romer, 1956)
- Tropidophiidae (Brongersma, 1951)
Many species are rare and endangered. Below is a description of some of the varieties of boas.
- Madagascar boa constrictor ( Acrantophis madagascariensis)
It lives in wooded areas in the north of the island of Madagascar. The length of the boa constrictor reaches 2-3 meters. The upper part of the snake's body is decorated with a pattern formed by diamond-shaped spots, and the skin on the sides has a complex pattern of concentric eye spots. The belly of this reptile is painted in grayish-olive tones with dark blotches. The entire body has a strongly pronounced blue-green metallic hue.
- Woody Madagascar boa constrictor ( Sanzinia madagascariensis, synonym Boa manditra)
It is a typical endemic to Madagascar. Adult snakes of this species can reach a length of 2.13 m, although most of them are only 1.2-1.5 m long, with females being larger than males. The color and size of woody boas depend on their habitat. In the western part of the island, larger individuals are found, painted in yellow-brown colors, and in the eastern part, grayish-green or pure green. Regardless of their distribution area, these reptiles prefer to settle near open water bodies. They are most active at twilight and night hours. Wood boas spend almost all the time in the dense crown of trees or bushes, near the water, although they can hunt on the ground, usually descending from the trees at night.
- Common boa constrictor ( Boa constrictor)
Inhabits the countries of South and Central America, as well as the Lesser Antilles. It was brought to the state of Florida, where it successfully took root. The size of adults is practically independent of gender - they can be up to 5 meters long. An ordinary boa constrictor weighs from 10 to 15 kg, although the weight of some individuals exceeds 30 kg. The back of these reptiles is colored in different shades of light brown, coffee or red, on which transverse dark brown stripes of a bizarre shape with yellow spots inside are clearly visible. The sides of an ordinary boa constrictor are decorated with dark rhombuses, inside of which, as well as on the back, yellow spots are visible. These boas lead an active nocturnal lifestyle, so they go hunting already at dusk.
- Kandoya ribbed, or keeled-scaled Pacific boa constrictor, ( Candoia carinata)
Previously, it belonged to the pseudopod family, and since 2014 it has been assigned to a separate Candoiidae family. There are two subspecies, slightly different from each other and living in New Guinea and the islands located nearby (Sulawesi, Mooluk, Santa Cruz, Solomon). Adults rarely grow up to 1.5 meters in length. The weight of a boa constrictor varies from 300 g to 1.2 kg. The color of the back and sides of the kandoya is olive gray, yellowish or light brown shades. A rather wide dark brown zigzag stripe runs along the back of the snake. This species of boas lives in trees, where it usually hunts in the evening and at night.
- Dog-headed boa constrictor, he is green tree boa (Corallus caninus)
Lives in the humid forests of South America, along the Amazon basin. The species got its name because of some external similarity between the snout of a boa constrictor and the head of a dog. Adults are often 2-3 meters long. The arboreal lifestyle caused the bright green color of the back and sides of this reptile. The yellow color of the belly, as well as white spots that merge into thin stripes running along the back and forming a clear diamond-shaped pattern, serve as an excellent disguise in the lush crown of vegetation. Newborns and juveniles are colored red-orange (coral). The front teeth of a boa constrictor, holding prey, can reach a length of 38 mm. In the daytime, the dog-headed boa rests, and crawls out to hunt with the onset of dusk.
- Garden boa constrictor (narrow-bellied boa constrictor) ( Corallus hortulanus)
It lives in humid forests in the south of Colombia and Venezuela. There are populations in the north and west of Brazil and Ecuador. In addition, the habitat includes Trinidad and Tobago, Suriname, Bolivia and other countries in South America. The average length of a boa constrictor ranges from 1.5 to 1.8 meters, although some specimens can reach 2.5 meters. The color of garden boas can be varied: from yellow, orange and red to light gray, brown or even black. On the back there are contrasting blurry spots, which are replaced by clearer rhombuses on the sides. During the day, the boa constrictor rests in the hollows of trees or abandoned bird nests, and at night it goes hunting. On rare occasions, it descends to the ground.
- Rainbow boa ( Epicrates cenchria)
Also has the name aboma... The species inhabits the humid forests of Central and South America. You can meet this beautiful reptile in Argentina, Brazil, Peru and other countries of the South American continent. Adults reach a length of 1.5-2 meters. The main body color of rainbow boas depends on the subspecies and can be brown, reddish or fawn. In some subspecies the body has a solid color without spots, in other subspecies there are dark or light spots on the body or white thin longitudinal stripes. All boa constrictor scales have a metallic hue. Despite the fact that this boa constrictor knows how to swim perfectly, it leads a terrestrial life.
- Black and yellow smooth-lipped boa constrictor (Chilabothrus subflavus, syn. Epicrates subflavus)
It is a fairly rare endemic species found in Jamaica. In English, the name of this snake sounds like "Jamaican boa constrictor". Females are slightly larger than males and grow up to 2 meters or more. The front part of the snake's body is yellow with dark blotches, which increase in size closer to the tail and merge into a single color on the tail, forming a black-brown background with small yellow spots. The tail of the boa constrictor is black, the head is painted in grayish-smoky tones. The snake's eyes are yellow, with characteristic stripes behind the eyes. The juveniles are pinkish-orange in color with indistinct stripes throughout the body. Jamaican boas inhabit moist coastal and mountain forests, lead a terrestrial lifestyle and are very active at night. Often, black and yellow boas hunt bats; rodents and various birds are also included in the diet.
- Dominican smooth-lipped boa constrictor (Chilabothrusfordii , syn. Epicrates fordi i )
Distributed on the islands of Tahiti and Gonav. Representatives of this species are rare and small in size, reaching a length of 85-90 centimeters, and females are much larger than males. The body of individuals is rather slender, painted in reddish or light brown tones, therefore this snake also has the informal name "red boa constrictor". Dark spots of various shapes are located over the entire surface of the skin. Under the rays of the sun, the scales shimmer with a variety of colors. Dominican boas lead a secretive land-based lifestyle, hunting at night.
- Giant anaconda ( Eunectes murinus)
It is rightfully considered the largest reptile of the boa snake family. The water boa, as it was called before, refers to. There are some individuals, the length of which exceeds 5 meters. Some sources even indicate a maximum length of 11 meters. The weight of an anaconda can exceed 100 kg (for example, National Geographic indicates a maximum weight of 227 kg). Along the entire back of the snake, painted in dark green, there are two rows of brown spots. On the sides, the spots are yellow and edged with a dark border. The belly is pale yellow and covered with black spots. The giant anaconda is found in the rainforests of South America, where it lives in the waters of rivers and swamps, including the Amazon. It hunts both at night and during the day.
- Sandy boa ( Eryx miliaris)
Previously, it belonged to the pseudopod family, and now it is included in a separate family of Erycidae. The snake is perfectly adapted to the burrowing lifestyle. The boa dwells in the desert regions of Central Asia, it is found in the eastern territories of the Ciscaucasia. A snake with a body reaching a length of 40-80 cm is painted in yellow-brown shades; brownish spots with blurred outlines stand out against the general background. The head of the sand boa has a flattened shape, and the eyes look almost vertical. The activity of the reptile depends on the season: in spring and autumn, the animal is active during the day, but in the summer it prefers to hunt exclusively at night. The food of the sand boa is small birds, lizards, as well as rodents, into whose holes it quietly crawls.
- Mascarene boas
A family that includes 2 genera (the genus Bolieria and the genus Arboreal Mascarene boas), whose representatives are endemic to the small island of Round, located northwest of Mauritius. The existence of the first kind, the only representative of which is multifilament bolieria (Bolyeria multocarinata ), today it is being questioned - most likely, this snake disappeared due to changes in habitat conditions. Woody Mascarene Boa (Schlegel Mascarene Boa) ( Casarea dussumieri) Is a very rare and endangered snake, so special programs are being developed on the island to restore the population. The length of the boa constrictor reaches 1-1.5 meters, between the head and the body there is a pronounced neck interception, the tail of the snake is long, with a sharp tip. The color is greenish-olive, longitudinal broken lines of a dark tone run along the main color. On the head of the reptile there is a lyre-like pattern.
