Gills are a necessity for underwater life: gills allow fish to absorb oxygen from water and release carbon dioxide, which allows them to “breathe” underwater. Unlike mammals, fish are cold-blooded (ectothermic). Hagfish, of the class Myxini / m ɪ k ˈ s aɪ n aɪ / (also known as Hyperotreti) and order Myxiniformes / m ɪ k ˈ s ɪ n ɪ f ɔːr m iː z /, are eel-shaped, slime-producing marine fish (occasionally called slime eels).They are the only known living animals that have a skull but no vertebral column, although hagfish do have rudimentary vertebrae. The respiratory organs are the gills and the organs of locomotion are paired and impaired fins. Paired and unpaired fins represent the appendages. Fish Sense Activity With "Lateral Lines" Although many fish have excellent vision, they don't quite … The following are the general characteristic that all the fish species posses: All the species of the fish found in the world are classified into the following three groups.

This adaptation also helps the fish to survive in waters that do not have adequate levels of oxygen. Some have a spindle-shaped or elongated body as well. Other species are able to survive in wider temperature ranges. As a result, colder waters decrease a fish’s body temperature, which can make them sluggish or go dormant during cold spells (like during the winter months in a lake, for example).
