Like other boas, anacondas lack venom with which to neutralize their prey. Large anacondas often weigh more than 200 pounds, but the longest snake on Earth is the reticulated python ( Python reticulatus). The green anaconda is the world’s heaviest snake, but not the longest. Green anacondas may be on there way to becoming established as an invasive species in parts of southern Florida like its boa cousin, the Burmese python. The biggest and best known are the green anacondas, which live live in wetlands and river basins through tropical South America, including parts of Brazil, Colombia, Venezuela, Guyana, Surinam, Bolivia, Peru, and Ecuador. beniensis), and the dark-spotted anaconda ( E. There are four species of anaconda today: Green anacondas ( Eunectes murinus), yellow anacondas ( E. Anacondas are members of the boa family.Īnacondas belong to Boinae, the family of large, non-venomous snakes collectively called boas. Read on for more gripping facts about these massive snakes. But you may not know that they give birth to live young and can stay underwater for up to 10 minutes on a single breath. CNN.Most people know that green anacondas are huge.

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.
