Answer 2

The description you provided sounds like it could be referring to a crocodile or an alligator. Both of these reptiles can walk on land, swim in water, have long tails, big mouths, and are typically green in color. They are similar in appearance and behavior, but they have different geographic distributions and some subtle physical differences.
