Eastern Crayfish

Cambarus bartoni

Size: to 3"

Habitat: small streams, sometimes ponds and lakes

Notes: Active at night, hides in burrows or under objects during the day.

Compare freshwater crayfish with marine lobsters.

Blue coloration is the crayfish equivalent of albinism, and also occurs in lobsters. Individuals like this have little chance of surviving in the wild.

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.
