Anatomy and Terms
| Fish can be broken down into six distinct sections which are fins, skin, vertebrae, jaw, organs, and reproductive system. So, I will endeavour to give as much information as I can and will be updating this page for awhile. Let’s start with the fins. |
|
Fins The first distinctive feature of a fish are the fins. These are made up of bony spines which protude from the fishes body and are joined together in a webbed fashion and covered with skin or appear as a flipper. The purpose of the fins are to aid in the ability of a fish to swim. They can also be used for gliding or crawling. |

| Here are the labels and description for these fins. | |
| Abdominal Pelvics: | Pelvic fins located on the abdomen far behind the pectoral fins; pelvic bones do not attach to pectoral girdle. |
| Accessory Pelvic Appendage: | A tapered fleshy lobe above the base of the pelvic fin. |
| Adipose fin : | A small fleshy fin with no rays, located between the dorsal and caudal fins. |
| Anal Fin: | The fin located on the ventral median line and behind the anus. |
| Caudal Fin: | Simply, the tail fin. |
| Dorsal Fin: | The fins located on the back of fish and in front of the adipose fin, if it is present. A fish can have up to three of them. These dorsal fins serve to protect the fish against rolling, and assists in sudden turns and stops. |
| Jugular Pelvics: | Pelvic fins in front of the pectoral fins. |
| Pectoral Fins: | The anterior(front) paired fins, attached to pectoral (shoulder) girdle. |
| Pelvic Fins: | Posterior paired fins, located in the abdominal position or towards the rear. |
