Bowfin (Amia calve)

The bowfin is a primitive fish that lives in muddy bottomed lakes and marshes. Sometimes called "dogfish," bowfins are often seen gulping air at the surface. They can grow to over 3 feet long. The males guard the eggs in a circular nest hidden among water plants, and also protect the young after hatching, as shown in this poster. These fish are predatory, feeding on other fish and crayfish. They are not highly regarded as a food or game fish.
