![]() Other common names include chij-chan ( Mayan), jiboia ( Latin American), and macajuel ( Trinidadian). Within the exotic pet trade, it is also known as a "BCC", an abbreviation of its scientific name, to distinguish it from other boa species, such as Boa imperator or "BCI." Īll subspecies are referred to as "boa constrictors", and are part of a diverse group of New World boas referred to as "red-tailed" boas, comprising the species Boa constrictor and Boa imperator. Only one other vertebrate animal shares this trait, the theropod dinosaur Tyrannosaurus rex. Though all boids are constrictors, only this species is properly referred to as the "boa constrictor" - an instance of an animal having the same English common name and scientific binomial. This article focuses on the species Boa constrictor as a whole, and on the nominate subspecies B. A staple of private collections and public displays, its color pattern is highly variable yet distinctive. The species is native to tropical South America. The boa constrictor is a member of the family Boidae. CNN.The boa constrictor (scientific name also Boa constrictor), also known as the red-tailed boa, is a species of large, non-venomous, heavy-bodied snake that is frequently kept and bred in captivity.

The species is also hunted by humans for its skin. Juveniles and the occasional adult may be taken by caimans, larger anacondas, jaguars, cougars, some canids such as the crab-eating fox, mustelids, and raptors. Cannibalism has been observed in this species, though it is not clear how often this occurs. The prey-to-predator weight ratio is often much higher than for other types of Boidae. Larger specimens can prey upon larger animals, such as brocket deer, capybaras or peccaries. Their prey consists nearly exclusively of aquatic or semi-aquatic species, including a wide variety of mammals, birds, reptiles, amphibians, fish and eggs. Observations and analysis of gut and waste contents from regularly flooded areas in the Pantanal region of southwestern Brazil indicate that they are generalist feeders that employ both ambush predation and wide-foraging strategies. Most predation occurs from June to November, when flooding has somewhat subsided and wading birds are the most common prey. The yellow anaconda forages predominantly in shallow water in wetland habitats. The species appears to have been introduced in Florida, although it is unknown whether the small population (thought to derive from escaped pets) is reproductive. It prefers mostly aquatic habitats, including swamps, marshes, and brush-covered banks of slow-moving rivers and streams. The range of the yellow anaconda encompasses the drainage of the Paraguay River and its tributaries, from the Pantanal region in Bolivia, Paraguay, and western Brazil to northeastern Argentina and northern Uruguay. ![]() The color pattern consists of a yellow, golden-tan or greenish-yellow ground color overlaid with a series of black or dark brown saddles, blotches, spots and streaks. They commonly weigh 25 to 35 kg (55 to 77 lb), but specimens weighing more than 55 kg (121 lb) have been observed. Females are generally larger than males, and have been reported up to 4.6 m (15 ft 1 in) in length. In the Ohrada Zoo, Hluboká nad Vltavou, Czech RepublicĪdults grow to an average of 3.3 and 4.4 m (10 ft 10 in and 14 ft 5 in) in total length. ![]()
