Which is the largest group among vertebrates?

                  Vertebrates represent the majority of life in the phylum Chordata. There are more than 65,000 species among vertebrates. Of these, the fishes constitute the majority. There are thousands of fish species across the globe. The fish diversity is spread across lakes, rivers, streams, seas, bays and oceans. They are found in the cold Arctic, in the hot tropics and in other temperate zones. When it comes to the number of species or individuals, fishes outnumber all other vertebrates.

                   Do you know that a scientist who studies fishes is called and an ichthyologist? The word comes from two Greek words: ‘ichthyos’, meaning fish, and ‘logos’, meaning study.
