Midwater Fishes

Freshwater gamefish such as trout and bass may not be taken by spear by divers. However, in some places, it may be legal to spearfish for carp, catfish, suckers, and other "rough" fishes - check local regulations.

Shellfish

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.

Insects

Insects are almost completely lacking in the marine environment. I recall something about saltwater having a very bad effect on their lungless respiratory system ( although this does not affect spiders. ) Insects are quite common in freshwater environments though, both as larvae and adults. A little digging can turn up myriad types, but be careful, some of them can bite very painfully.

Freshwater Plants

These are all true plants. In freshwater, much of the algal growth is in the form of slimes that grow on rocks, plants, and other surfaces, and of course microscopic phytoplankton. While freshwater algae is an important part of the ecosystem, it is not very remarkable to the typical scuba diver.
