Class Placodermi (armoured fish) † Class Acanthodii ("spiny sharks", sometimes classified under Actinopterygii) † Superclass Osteichthyes (bony fish) Class Actinopterygii (ray finned fishes) Clade Sarcopterygii (lobe finned fishes, ancestors of tetrapods) The above scheme is the one most commonly encountered in non-specialist and general works.
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups.Ambiguous common names are accompanied by their possible meanings.
For example, the human species is uniquely identified within the animal kingdom by the name Homo sapiens. No other species of animal can have this same binomen (the technical term for a binomial in the case of animals). Prior to Linnaean taxonomy, animals were classified according to their mode of movement.
This is a list of fish with common names that are based on the names of other animals. The names listed here may refer to single species, broader taxa (genera, families), or assortments of types. Where names are ambiguous, the various meanings should be listed here.

Trunk, a single woody stem came about in unrelated plants: paleozoic tree forms of club mosses, horsetails, and seed plants. The marine animals sea lily crinoid, looks like a terrestrial palm tree. [230] Palm trees form are in unrelated plants: cycads (from the Jurassic period) and older tree ferns. [231]

In some parts of Asia, swamp eels and one species of spiny eel, Mastacembelus erythrotaenia, are valued as food and sometimes are kept in ponds or rice fields. Except for a few mastacembelids, they are rarely seen in home aquaria. The fish have numerous sharp dorsal spines and belly thorns which, together with its sliminess make them extremely ...
