(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 on to the head of the team leader as he slept.
    (7) The snake has been named silver boa because it is metal colored 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 Muworki 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."
