  • Description:   Harmless. Strongly keeled scales; belly with dark brown, orange, yellow, red and gray halfmoons and speckles, widely spaced and scattered on the front part of a gray or whitish belly; dark brown complete bands on the front part of the body and alternating rows of brown or gray blotches on the back and sides of the rear portion of the body; old adults are uniform brown or gray.

  • Habits:    Found in almost any aquatic situation, from rocky streams and rivers to swamps, lakes and marshes. Active from March to November; becomes nocturnal in the summer.
