|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.|
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.|
