Ray-finned
fishes
Chondrostei - bichirs, sturgeons,
and paddlefishes
• Sturgeons and paddlefishes have an almost entirely cartilaginous skeleton
• Swim bladder, not lung, present
• Huso huso, the beluga sturgeon, is the largest actinopterygian fish
• Sturgeons are found throughout the north temperate regions in fresh- and saltwater
• There are two species of paddlefishes, one in the eastern US (including Alabama) and one in China
• Sturgeons with bony plates along side, paddlefish with some small embedded plates, but mostly naked.
• Caudal fin heterocercal
Bichirs
• The relationships of the bichir with the sturgeons + paddlefish (Acipenseriformes) is uncertain
• Bichirs are unique in that they seem to have re-evolved somewhat lobelike paired fins
• Bichirs have a paired lung
• Ganoid scales
• Diphycercal caudal fin
