| Second, in most basal ray-finned fishes such as sturgeon and trout a single dorsal fin is present and is supported by flexible fin rays. |
| Some of the common fish species include the freshwater drum, sheepshead, lake sturgeon, spotted suckers, common red-horse, and pumpkinseed. |
| Lescarbot also observed Mikmaq spearing salmon, sturgeon and dolphins and jigging for cod. |
| Within the Chondrostei, only sturgeons, bichirs and paddlefishes survive today, and many are threatened. |
| Other fishes, such as catfishes and burbots, probably eat the young shovelnose sturgeons. |
| The tail fin of most ray-finned fish, with the exception of sturgeons and paddlefish, is homocercal, nearly symmetrical about the midline. |
