The baby boa's diet changes as it grows. Islands included in the boa constrictor range are: the Lesser Antilles, Trinidad, Tobago, Dominica, and St. Lucia. At 3-4 years, Boa constrictors become reproductively mature and reach the adult size of 6-10 feet (1.8-3 m), although they continue to grow at a slow rate for the rest of their lives. Boa constrictors are found from northern Mexico to Argentina. [41] Proper animal husbandry is the most significant factor in captive lifespan; this includes providing adequate space, correct temperatures and humidity, and suitable food items. Copeia, 3: 532-533. Their jaws can stretch wide to swallow large prey whole. living in landscapes dominated by human agriculture. Females are also widely dispersed. However, unlike other snakes, it shows little inclination toward swimming in water. How does a boa constrictor protect itself? (Mattison, 2007; O'Shea, 2007; Stone and Holtzman, 1996), Boa constrictors are popular in the pet trade. Boa constrictors have two functional lungs, a condition found in boas and pythons. Boa constrictors are found in the jungles and rainforests of Central and South America. Habitat Boa constrictors can be found in different habitats including rainforests, agricultural areas and deserts in trees or on the ground. As in other snakes, boa constrictors shed their skins periodically as they age, allowing them to grow and preventing the scales from becoming worn. Cryptic coloration, also known as camouflage, is an important aspect of survival for tree boas. 1996. In many cases, a boa constrictor of unknown geographical origin may be impossible to assign to a subspecies. Boa constrictor predation pressure may help to regulate opossum populations and decrease potential trasmission of leishmaniasis to humans. Boa constrictors wear some of the most distinctive markings of all reptiles. This is because some venomous snakes have deadly bites. It takes the snake about 46 days to fully digest the food, depending on the size of the prey and the local temperature. having a body temperature that fluctuates with that of the immediate environment; having no mechanism or a poorly developed mechanism for regulating internal body temperature. 2003. Make a donation to the Smithsonian's National Zoo and Conservation Biology Institute today! (Mattison, 2007; O'Shea, 2007; Pough, et al., 2004; Stafford, 1986), Males are polygynous; each male can mate with multiple females. Unconsciousness and death likely result from shutting off vital blood flow to the heart and brain, rather than suffocation as was previously believed; constriction can interfere with blood flow and overwhelm the prey's usual blood pressure and circulation. In 2010, a boa constrictor was shown to have reproduced asexually via parthenogenesis. An introduced population exists in extreme southern Florida,[25] and a small population on St. Croix in the U.S. Virgin Islands now appears to be reproducing in the wild. Their housing also needs high humidity and high temperature, these specifications must be maintained for the snake to remain healthy. Boa constrictors rarely, if ever, attack humans except in self-defense. Boa Constrictors will also feed on lizards, small mongoose, bats, rats, squirrels, iguanas and other small mammals. Polymorphic characteristics may be inherited because the differences have a genetic basis, or they may be the result of environmental influences. .

This article focuses on the species Boa constrictor as a whole, and on the nominate subspecies B. c. constrictor. But despite this abundance of species, our knowledge of many Amazon reptiles is still poor. It is commonly believed that boa constrictors subdue their prey by crushing their bones or squeezing their lungs to suffocate them, but recent research on the constriction method revealed that these snakes employ a different strategy all together. How are howler monkeys adapted to the rainforest? Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.

By consuming a wide range of prey species, these animals can thrive in a variety of microhabitats within the rain forest. Boa constrictor bites are painful bure are unlikely to be dangerous as long as standard medical care is obtained. [26] Like all snakes, boa constrictors in a shed cycle are more unpredictable, because the substance that lubricates between the old skin and the new makes their eyes appear milky, blue, or opaque so that the snake cannot see very well, causing it to be more defensive than it might otherwise be.
