Also, an anaconda that has recently eaten will look much larger than one that hasn’t, causing exaggerated estimations of size. People who see anacondas in the wild are likely to overestimate their length due to fear. It is hard to stretch out a captive anaconda, not to mention potentially dangerous for the snake, according to Rivas. Green anacondas’ length is still a matter of debate, said Heyborne. Their sides are sometimes more yellow than green with egg-shaped spots with yellow centers, according to the Jacksonville Zoo. They have black or brown egg-shaped spots on the mid-to posterior back of their bodies.
True to their name, these are greenish-brown, olive, or greenish-gray. Their spotted, green, yellow and brown color palettes allow them to blend in with tropical rivers and rainforests. In fact, anacondas exhibit the largest sexual dimorphism (with the female being larger) of any tetrapod species, according to Jesus Rivas, a herpetologist and founder of the Anaconda Project.Īnacondas’ coloring and size depends on the species. Males have larger spurs than females, though females are overall larger and longer snakes. Near their cloacal region, anacondas have spurs on their scales.

They have loose, soft skin that can handle a great deal of water absorption, according to the University of Michigan’s Animal Diversity Web (ADW). They have a thick black stripe that runs from the eye to the jaw.Īnacondas have small, smooth scales that grow larger toward the posterior of their bodies. All anacondas have nostrils and eyes on the tops of their heads, which allow them to see above the water while remaining mostly submerged. They have thick necks and narrow but large heads. Anacondas are stocky, muscular snakes that are thicker than other boas.
