A new species of snake has been discovered on a remote island in the Bahamas. Scientists identified 20 of the one-meter-long snakes during two trip to the Caribbean islands. The second trip was make in October last year. One of the creatures made a dramatic appearance by moving onto the head of the team leader as he slept. The snake has been named Silver Boa because it is metal-coloured and the first specimen found was climbing a silver palm tree. The team was led by Dr. Graham Reynolds from Harvard University. The scientist confirmed the snake was a previously unknown species after conducting a genetic analysis of tissue samples. Commenting on the find, snake expert Robert Henderson, from the Milwaukee Museum of Natural History, said, “Worldwide, new species of frogs are being discovered and described quite regularly. New species of snakes, however, are much rarer.”
