They include some extant aquatic species, commonly called "fishes" (see phylogenetic tree above). In the Vertebrate tree illustrated below, there are other Vertebrate groups also referred to as "fishes". Do fishes constitute a monophyletic group? → The simple term “fish" is no longer used alone for phylogenetic classification, although the word is quite usual. What definition could you give for a fish?
