The markings are more recognizable in juveniles. The belly is dark gray with small, yellow half-moon spots. When fully grown, green water snakes can be 4.5 feet long. You might encounter this species around streams, ditches, bayous, marshes or swamps in the southeastern two-thirds of the state. Areas thickly grown with water plants are preferred habitat.
Fish are their primary food.
Yellow-bellied water snakes grow to slightly more than five feet. An unmarked belly of yellow or orange-yellow distinguishes this species. Adults have no markings on their backs, which may be dark reddish-brown, brown or greenish. One of this snake's interesting habits is wrapping its tail around a tree branch and dangling its head in the water to catch fish. The blotched water snake also has a yellow belly, but its back has a series of light crossbars with dark borders.
