Suckers live in any kind of water, from fast-flowing streams to large lakes. They vacuum up invertebrates from lake and stream beds.
Redhorse Suckers are similar, but sport colorful fins, like some kind of tropical aquarium fish.
There are essentially two choices of weapon for spearfishing: pole spears and spearguns. The speargun is probably the first thing that comes to mind for most readers - conjuring up images of Seahunt, James Bond, and countless other TV shows and movies. Everyone knows what a speargun looks like - a roughly pistol-shaped device that fires a two-foot steel dart. Everyone probably also has a pretty good idea what a pole spear looks like, but an underwater pole spear is a different in form and use from a terrestrial javelin. Rather than throwing it ( which would be difficult to impossible underwater ) a pole spear ( or "Hawaiian sling" ) has a loop of rubber tubing at the butt end that is used to launch it directly from the hand, the shaft sliding through the loosened hand without ever leaving it.
