Knowra Cusk-eel Cusk-eel Cusk-eels are marine bony fishes in the family Ophidiidae, typically with elongated bodies and long dorsal and anal fins. Many live near the seafloor, and some inhabit deep water.
Ophidiidae : Ophidiidae is a family of marine fishes that includes cusk-eels and brotulas. This family is the taxonomic group to which cusk-eels belong.
Deep-sea fish : Deep-sea fish are fishes adapted to life in the deep ocean, where light and food are scarce. Many cusk-eel species live at depths that place them among deep-sea fishes.
Pearlfish : Pearlfishes are slender marine fishes in the order Ophidiiformes, including species that live inside invertebrates. They share an order with cusk-eels but have distinctive lifestyles and body forms.
Common cusk : The common cusk, Brosme brosme, is a large North Atlantic fish in the family Lotidae. Despite its name, it is not a cusk-eel; it is a useful example of common-name confusion.
Ophidiiformes : Ophidiiformes is an order of ray-finned fishes that includes cusk-eels and pearlfishes. Cusk-eels belong to this broader order of fishes.
Bathyal zone : The bathyal zone is the ocean region from the continental slope to roughly 2,000 meters deep. Some cusk-eels inhabit this dim, high-pressure ocean depth range.
viviparous brotula : The viviparous brotula is a marine fish in the family Bythitidae that gives birth to live young. It is a neighboring ophidiiform fish, illustrating the order's varied reproductive biology.
Kingklip : Kingklip is a South African marine fish in the family Ophidiidae, valued as food. It is a familiar food fish among the cusk-eel family's relatives.
Ray-finned fish : Ray-finned fishes are vertebrates whose fins are supported by bony or cartilaginous rays. Cusk-eels are members of this dominant group of bony fishes.
Abyssal zone : The abyssal zone is the deep-ocean region, generally about 3,000 to 6,000 meters below sea level. Certain cusk-eels occur on or near the abyssal seafloor.
