Amazing Facts About Catfish
Have you ever wondered how many species of catfish swim in the waters of the world? I have, so this month I did a bit of online research to see what I could learn.
As it turns out, catfish comprise an incredibly large and diverse group of animals—much larger, in fact, than most people realize. To date, more than 3,400 species have been described. This means that about one in four species (23 percent) of all freshwater fishes is a catfish. One in 10 species (11 percent) of all fishes, including every saltwater and freshwater fish now known, is a catfish. One in 20 species of all vertebrates—which includes all mammals, birds, reptiles, amphibians and fish—is a catfish.
