Over the huge period of time fish have lived on this planet, they’ve developed to fill all kinds of aquatic niches, and fish are by far the largest group of vertebrates.

Among the many world’s fish are ocean predators resembling sharks and barracudas; meals fish resembling cod and tuna, migratory species resembling salmon and eels; freshwater species resembling carp and pike; and deep sea fish such because the humpback anglerfish and Mariana snailfish.

On this web page you’ll meet these and plenty of different kinds of fish. You’ll uncover the three most important kinds of fish, and discover fish range with an inventory of attention-grabbing fish from all around the globe.
