He noted that active foraging behaviors have been noted in places with less dense prey populations.īoa constrictors’ diets are composed mostly of small mammals like rats and squirrels. Hunting and dietīoa constrictors tend to be ambush predators that sit and wait for desired prey to pass from their tree perch or burrow, said Heyborne. Along with their tongues, which gather sensory information as they do for most snakes, boa constrictors’ eyes are the primary tools through which they perceive the world, especially since boa constrictors do not have heat-sensory pits like most other members of the Boidae family do. When not clouded, boa constrictors have excellent vision. This affects their vision and as a result, they often stay still for a few days until their vision returns to normal, Heyborne said. When they’re shedding, boa constrictors “tend to become more easily stressed and thus more aggressive,” though that tends to vary from snake to snake and across populations.Īlso when shedding, boa constrictors’ eyes cloud over as a lubricating substance develops under the old skin layer to shield the eye. “Like all snakes, they must shed their skin in order to grow,” said Heyborne. Sometimes they hide in the burrows of medium-sized mammals. Because of their large size, they tend to move in a straight line instead of slithering back and forth like smaller snakes, according to the San Diego Zoo. Though they are good swimmers, they prefer to be on dry land or in trees. These snakes, especially young ones, are semi-arboreal, said Heyborne. They are mostly nocturnal, though they will sometimes come out during the day to sun themselves in cooler temperatures. Behaviorīoa constrictors are typically solitary, said Heyborne. They are often found near streams or rivers, according to the ADW. They can also be found in dry tropical deserts and semi-deserts, woodlands, scrub and agricultural areas. When they do reside in rainforests, they tend to stick to the edges or clearings. Though stories often depict boa constrictors living in jungles, their habitats are actually much more diverse. Previously, scientists thought that all members of the family Boidae were New World snakes, but certain boa species have been discovered in remote areas such as Mauritius and New Guinea, according to the San Diego Zoo. They are also found on islands in the Caribbean and off the Pacific coast. They are found throughout the Americas, ranging from northern Mexico through Central America and into Peru on the west side of the Andes and south to Argentina on the east side. Rowling.Boa constrictors are New World snakes, meaning they live exclusively in the Western hemisphere, according to the ADW. There was a popular fan theory that Nagini and the snake from the zoo were the same, however this has been debunked by J.Both of these snakes are non-venomous, using Constriction to kill their prey, while Nagini is venomous. In the film adaptions of Harry Potter and the Goblet of Fire, Harry Potter and the Order of the Phoenix and Harry Potter and the Half-Blood Prince, Voldemort's pet snake, Nagini, is portrayed as a Dumeril's boa while a in Harry Potter and the Deathly Hallows she is portrayed as a Reticulated Python.Also in the film, after the boa is freed the glass reappears trapping Dudley on the inside of the pen.In both the book and the film, the snake winks at Harry, despite the fact that snakes have no eyelids.In the Brazilian dub, the boa constrictor comes from Brazil according to the first movie (referencing the book), but its species is not mentioned in the second movie.In the film adaptation of Harry Potter and the Philosopher's Stone, the boa constrictor from Brazil is changed to a Burmese Python, and so is the mention of it in the film adaptation of Harry Potter and the Chamber of Secrets.The animated Nagini as a Dumeril's Ground Boa The boa then said to him " Brazil, here I come. Harry unknowingly used underage magic by making the glass of its enclosure vanish, freeing the boa. On 23 June, 1991, Parselmouth Harry Potter spoke to a boa constrictor from Brazil that was in captivity at a Zoo in Surrey.
