Alaska has but one species of snake, the common garter snake. It was thought that Hawaii had no snakes but, in recent times, snakes have been spotted and are of a concern. It is illegal to have a pet snake in that state and illegal to import them. The snakes seen were probably smuggled into the state and released or they came in on freight shipments from elsewhere. All other states have a variety of snakes. The Yellow-Bellied Sea Snake is found in the waters surrounding Hawaii, however.
There are different species of snakes found in Montana, such as rattlesnakes, milk snakes, garter and gopher snakes. Some snakes found in the Kalispell MT can be the Eastern racer, milk and gopher snakes.
