(5) 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 trips to the Caribbean islands. The second trip was made in October last year.(6) One of the creatures made a dramatic appearance by moving onto the head of the team leader as he slept. (7) 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."
