A medium-sized, greenish fish, the bowfin can be found in clear lakes and slow streams through much of Minnesota.Bowfin survive in murky, oxygen-depleted water by rising to the surface and gulping air into their air bladders.his primitive fish was around when dinosaurs roamed the earth. It is also known as a dogfish. The bowfin is a tubular, olive-green fish with a scaleless head and two barbels on its face. Its dorsal fin stretches most of the length of its back.
Apart from the tail or caudal fin, fins have no direct connection with the spine and are supported by muscles only. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes, such as moving forward, turning, keeping an upright position or stopping.Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. fish can have up to three dorsal fins. The dorsal fins serve to protect the fish against rolling, and assist it in sudden turns and stops. 1  In anglerfish, the anterior of the dorsal fin is modified into an illicium and esca, a biological equivalent to a fishing rod and lure.
