Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. The paired fins, pe… The tail and head are each bonded to ABS flanges, and the flanges are screwed together with a gasket between them creating a waterproof fish body to protect the electronics. They provide a source of locomotion for fish and some other forms of marine life. See fish tail stock video clips. • It consists of many separate segments of bone or cartilage called vertebrae. In concluding this tale about tails, there is no doubt that close consideration of the shape and structure of the tail of many fishes and other marine animals will reveal a lot about an animal’s lifestyle and place in the marine environment. Fish tails appear in a variety of significantly different forms depending upon the lifestyle of the species. Some fish have specialist uses for their tales. The body covering is usually scaleless. Most females have wider tails than the males of the same species.

Now I am not suggesting that you start looking at tails before you check out faces and bodies, but experienced divers, ichthyologists, and other marine specialists are quick to point out that a good look at an animal’s tail can not only help you identify a species, but understanding the advantages and disadvantages of various tail shapes can provide you with valuable insight about the natural history of fishes and many other marine creatures that we routinely encounter.

The tail fin, in its final lash, may contribute as much as 40 per cent of the forward thrust. Animals such as crinoids, sea stars, sea cucumbers and crabs “walk” from place to place.

Fishes such as catfish have another fleshy lobe behind the dorsal fin, called an adipose (fat) fin that is not illustrated here. This discovery supports the belief that environmental factors as well as genetics play an important role in the body structure of many fishes. it helps the fish manuever in the water and helps it swim These cephalopods move by filling with water their mantle, the soft external body wall below the head.
