Goniobasis virginica
Size: to 1"
Habitat: flowing water
Notes: This is one example of the many small snails you may find during a freshwater dive. They are very common in Round Valley Reservoir, which is filled from the Raritan River.
This page lumps together representatives from crustaceans and mollusks. Freshwater typically has lower diversity than the ocean. However, this is just a tiny sample of what may be found.

You cannot go diving in New Jersey waters without seeing Comb Jellies. Up close, rainbow-like rows of tiny beating hairs called cilia may be seen - the Comb Jelly's only means of propulsion. Comb jellies do not sting, but they are still voracious predators, feeding on anything they can engulf. At night they may phosphoresce - watch the boat wake as agitated Comb Jellies flash in the dark like depth charges. Cnidarians are exclusively marine, although some are tolerant of brackish water as well.
