Cottonmouth - (Agkistrodon piscivorus)
The Cottonmouth (also called the Water Moccasin) belongs to the same family as the rattlesnakes. The Cottonmouth and the Copperhead are the only members of the family in the United States that don't have rattles. If you live where these snakes are found and you like to catch snakes, learn to identify these species. Unlike other water snakes, the Cottonmouth swims with its head well out of water. Although it may be observed basking in the sun during the day, it is more active at night. It preys on amphibians, fishes, snakes, and birds
