![]() ![]() Boas are semi-arboreal, spending much of their time among the lower branches of trees when young. Greater numbers can be found in the hills which surround the Pantanal region, and which are safer from seasonal flooding. In turn, boas are preyed on by birds, mammals, and even other snakes - especially when they're young and almost entirely defenceless.īoas are sometimes found near water sources, such as rivers are streams - but generally still within proximity to woodlands rather than in wetland areas. although this obviously depends on the size of the last meal. Small boas will feed around once a week, intermediate snakes will feed once every two weeks, and adults will probably only feed every 3-4 weeks. Their meals are few and far between - although younger snakes feed more often than larger ones due to the smaller size of their meals. However, due to their slow metabolism, boas aren't mindless killers attacking everything around them. Once the prey has been taken, the boa's tightening coils mean that the prey is quickly asphyxiated. Usually its all over within a fraction of a second. They strike quickly, latching onto their victim with sharp teeth - snatching it back towards them and very rapidly wrapping their coils around it. ![]() Although they have been known to actively hunt, boas are ambush predators which lie in wait for a potential meal to unwittingly wander too close. As boas increase in size then so does the size of their prey - allowing them to start taking bigger animals, even including ocelots. They're also primarily nocturnal - which is when they're more likely to come out - hunting birds, lizards and small mammals such as rodents. Boas are generally solitary, and don't approach or interact with other snakes unless it's time to mate. In the wild, snakes bask in the sun to keep warm, then move to shadier spots or even go swimming when it gets too hot. ![]() Like other snakes, Boas are cold blooded - getting heat from their surroundings. This red tail is more prominent in younger specimens. Typical species have 15 to 30 dark saddle-shaped markings along the length of their back - which increase in size and turn redder towards the tail. Most are tan or beige - although some can also appear very dark. There are 10 separate subspecies - but the distinctions between them aren't clear and it isn't unusual to find specimens exhibiting traits of multiple subspecies. It has a wide geographical range stretching from northern Mexico through to Uruguay and northern Argentina. It's a large bodied snake, with adults ranging from 1.8 to 3 metres. This has the scientific name Boa constrictor constrictor - one of the rare cases where the scientific name and common name are more or less the same. This is easily distinguished by its orange/black or chocolate skin with a sheen that refracts the light, demonstrating all the colours of the rainbow. Red-tailed boa, more commonly known simply as the Boa Constrictor, and.Within the Pantanal, there are two species of boa to look out for: Nonetheless, both have have a similar general appearance and the same method of killing their prey through constriction. Boas give birth to live young, whereas pythons lay eggs, and pythons have a wider head due to to the presence of an extra (supra-orbital) bone. Aside from geographical distribution, the other differences are that boas lack the heat-sensing pits that pythons use to track their prey. Firstly, pythons are restricted to areas around Africa and Australasia - whereas as (with a few exceptions) boas are restricted to the Americas. Raccoons and opossums often forage for food near the water’s edge, which is a habitat frequented by pythons in search of prey.Pythons and boas are frequently confused. The mammals that have declined most significantly have been regularly found in the stomachs of Burmese Pythons removed from Everglades National Park and elsewhere in Florida. Marsh rabbits, cottontail rabbits, and foxes effectively disappeared. In a 2012 study, populations of raccoons had dropped 99.3 percent, opossums 98.9 percent, and bobcats 87.5 percent since 1997. The most severe declines in native species have occurred in the remote southernmost regions of Everglades National Park, where pythons have been established the longest. ![]() Severe mammal declines in Everglades National Park have been linked to Burmese pythons. Pythons compete with native wildlife for food, which includes mammals, birds, and other reptiles. Non-native Burmese pythons have established a breeding population in South Florida and are one of the most concerning invasive species in Everglades National Park. ![]()
