Northern Water Snake
Nerodia sipedon
Size: to 42"
Habitat: in and around water
Notes: Not poisonous, but likely to bite if caught, with sharp, needle-like teeth. These snakes retreat into the water at the slightest disturbance, and are excellent swimmers, although they show no particular adaptations to it like oceanic sea snakes. Common small harmless Garter snakes are also often found around water. Most sport some variation of an attractive pattern of yellow/black stripes.
