Northern Water Snake

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.

algae
A garden of green and brown algae grows on a shallow rock. Enteromorpha (Hollow Green Weed) and Fucus (Rockweed)

In our waters, plants and algae are found only in shallow water where sufficient light can penetrate for photosynthesis. It would be unusual to find algae below 10-20 ft, so our wrecks and reefs, despite the profusion of attached organisms, are actually devoid of plant life! Of course, that is completely neglecting the microscopic algal plankton that is so profuse in our waters and so lacking in the clear water of the tropics.
