Actinopterygii

Actinopterygii, members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species.

Anatomical terms of location

Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans.

See Pachycormiformes and Anatomical terms of location

Aspidorhynchidae

Aspidorhynchidae (from Neo-Latin "shield-snouts") is an extinct family of ray-finned fish from the Mesozoic Era. Pachycormiformes and Aspidorhynchidae are Maastrichtian extinctions.

Coronoid process of the mandible

In human anatomy, the mandible's coronoid process (from Greek korōnē, denoting something hooked) is a thin, triangular eminence, which is flattened from side to side and varies in shape and size.

Filter feeder

Filter feeders are aquatic animals that acquire nutrients by feeding on organic matters, food particles or smaller organisms (bacteria, microalgae and zooplanktons) suspended in water, typically by having the water pass over or through a specialized filtering organ.

See Pachycormiformes and Filter feeder

Fish fin

Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim.
