One of the world’s most elusive snakes has resurfaced after a 64-year “manhunt” by scientists in Brazil. This particular snake is a Cropan boa (Corallus cropanii) and it was found by some workers in Brazil who identified it from "wanted signs" that they'd seen. It's a good thing they saw the wanted signs, too, because otherwise they would have killed the snake as they don't want to take chances with snakes. The Cropan boa, however, is not venomous. It has a yellowish belly, a back covered in black diamond patterns, and deep sensory pits lining the edge of its lips. It weighs 1.5 kilograms and most likely preys on small mammals and birds.
