Brazilian rainbow boas (Epicrates cenchria) are strikingly beautiful snakes native to Central and South America. Known for their iridescent scales that shimmer in the light, they exhibit a rainbow-like sheen, hence their name. Typically growing to 4-6 feet in length, these boas thrive in humid, tropical environments. They are non-venomous constrictors, preying on small mammals, birds, and occasionally reptiles. Rainbow boas are popular in the pet trade due to their unique appearance and relatively docile nature.
