![]() On the sides of its body, you can see spots with yellow-colored centers. This pattern can serve as camouflage in with the wet and dense vegetation of its habitat. If you think you cannot handle an enormous snake, green anacondas are not the one for you.Ĭolor-wise, the green anaconda has some oval spots of black all over its back that complements its dark green color. The females can grow as long as 16 feet, while their counterparts are about 10 feet long on average. The male anacondas are much tinier when compared to their female counterparts. The green anaconda also has a thick black stripe that is visible from its jaws across its eyes. They have thick necks, and their heads are narrow lengthwise but broad. Green anacondas are muscular and bulky members of the snake family that are thicker than other types of boas. ![]() The green anaconda is famous all over the world because of how big it is and our human misconceptions about their eating habits.

A female anaconda can give birth to as many as a 82 young, though typically the size of the litter ranges from 28 to 42 (Reed and Rodda, 2009).Īreste, M. The gestation period for the Green Anaconda is 6 to 10 months. Often the snakes cluster in a breeding ball which may consist of up to 13 males coiled around one female. The female is thought to lay down a pheromone trail, which attracts the male. Courtship often extends over several months and the mating period typically is from April to May. The Green Anaconda reproduces sexually and has internal fertilization. Predators of small anacondas include Crab-eating Foxes, tegu lizards, Crested Caracaras, caimans, and larger Green Anacondas (Rivas et al. Neonates and juveniles are particularly prone to predation, and seem to suffer high mortality within their first year. There are few records of attacks on humans, and no well-documented deaths (Rivas, 1998 Reed and Rodda, 2009).Īnacondas are not immune from predators. After a meal, an anaconda may not eat for weeks or months (Reed and Rodda, 2009). This species has a slow-acting digestive system it often takes days or weeks to digest food. They are known to consume large prey such as peccaries, capybaras, tapirs, deer, and sheep. The Green Anaconda swallows its prey whole, even prey much larger than the diameter of their mouths. Small individuals may climb trees to raid bird nests. The list of potential prey items of an anaconda is extensive and varied, and consists of birds, amphibians, reptiles, mammals, and fish. ![]() It immobilizes and kills its prey by using its jaws to hold on the prey while coiling its body around the animal and constricting until it dies from suffocation or other crushing injuries. This species is a constrictor, nonvenomous, and an ambush predator. Because of its aquatic nature, it is able to escape extremes in temperature variation. It often is found in seasonally flooded areas (Reed and Rodda, 2009). It can be found in deep, shallow, turbid, and clear waters, and lacustrine and riverine habitats. Ecology: The Green Anaconda is an aquatic snake usually found submerged under the water or near the water’s edge.
