How Do I Become a Fish Biologist?

Fishes are aquatic vertebrates that swim by gills, swim through the tail and trunk, and coordinate with fins, and feed on the upper and lower jaws. They belong to the subgroup of vertebrates in the chordate phylum. Generally, vertebrates are divided into Fish (53%), birds (18%), reptiles (12%), mammals (9%), amphibians (8%). According to the statistics of the late Canadian scholar "Nelson" in 1994, there are a total of 24,618 species of living species in the world, accounting for more than half of the named vertebrates, and new species of fish are constantly being discovered, with an average of about 150 species each year. It should have increased by more than 1500 species. At present, there are about 32,100 species of fish named worldwide.
