Wikipedia

  1. Holocephali

    Holocephali ("complete heads"), sometimes given the term Euchondrocephali, is a subclass of cartilaginous fish in the class Chondrichthyes. The earliest fossils are of teeth and come from the Devonian period. Little is known about these primitive forms, and the only surviving group in the subclass is the order Chimaeriformes. Chimaeriformes, commonly known as chimaeras, rat fish, or ghost sharks, include three living families and a little over 50 species of surviving holocephalans. These fishes move by using sweeping movements of their large pectoral fins. They are deep sea fish with slender tails, living close to the seabed to feed on benthic invertebrates. They lack a stomach, their food moving directly into the intestine. Extinct holocephalans were much more diverse in lifestyles, including shark-like predatory forms and slow, durophagous fish.

  1. holocephali

    Holocephali is a subclass of cartilaginous fish that includes species like chimaeras or ghost sharks. They are differentiated from other fish by their fused upper jaw, large pectoral fins, and the lack of scales in most species. Most of the species under Holocephali are deep-sea-dwelling and are consequently less well-known than their relatives, sharks and rays.

Webster Dictionary

  1. Holocephali

    The subclass Holocephali is a taxon of cartilaginous fish, of which the order Chimaeriformes is the only surviving group. Holocephali has an extensive fossil record that starts during the Devonian period. However, most fossils are teeth, and the body forms of numerous species are not known, or at best, poorly understood. Some experts further group the orders Petalodontiformes, Iniopterygiformes, and Eugeneodontida into the taxon "Paraselachimorpha," and treat it as a sister group to Chimaeriformes. However, as almost all members of Paraselachimorpha are poorly understood, most experts suspect this taxon to be either paraphyletic or a wastebasket taxon. It includes the rat fishes, rabbit-fishes and elephant-fishes. They preserve today some features of elasmobranch life in Paleaozoic times, though in other respects they are aberrant. They live close to the bottom and feed on molluscs and other invertebrates. The tail is long and thin and they move by sweeping movements of the large pectoral fins. There is an erectile spine in front of the dorsal fin, sometimes poisonous. There is no stomach, and the mouth is a small aperture surrounded by lips, giving the head a parrot-like appearance.
