[fishfreek]

Well I got some decent photos of some common critters that many people often ask the question "What is this?" so I figured we should have a thread with photos of common need to be identified critters.

This thread will be locked so only admins and mods can edit and add to this list. Should you have a good photo we might ask permisson to add it to the list.
