The word Sarcopterygii is derived from the Greek words sarkos meaning flesh and pteryx meaning fin. Pindaca finned fishes belong to the class Sarcopterygiae. Their paired fins are fleshy hence they are known as lobe finned. They are known as lungfish and coelacanth. Lungfish are widespread in Africa, South America and Australia. Coelacanths are widespread along the coast of the Indian Ocean and Indonesia. Scientists believe that from this class of fish, amphibians emerged as quadrupeds and terrestrials. There are currently 8 species of fish alive.
