Skates are cartilaginous fish belonging to the family Rajidae in the superorder Batoidea of rays. More than 150 species have been described, in 17 genera. Softnose skates and pygmy skates were previously treated as subfamilies of Rajidae, but are now considered as distinct families. Alternatively, the name "skate" is used to refer to the entire order of Rajiformes.

<i>Notoraja</i> Genus of cartilaginous fishes

Notoraja is a genus of skates in the family Arhynchobatidae. They are found in deep water in the Indian and western Pacific Oceans.

<span class="mw-page-title-main">Arhynchobatidae</span> Family of fishes

Arhynchobatidae is a family of skates whose members are commonly known as the softnose skates. It belongs to the order Rajiformes in the superorder Batoidea of rays. At least 104 species have been described, in 13 genera. Softnose skates have at times been placed in the same family as hardnose skates, but most recent authors recognize them as a distinct family. Members of the Arhynchobatidae can be distinguished from hardnose skates in having a soft and flexible snout, as well as a more or less reduced rostrum.

<i>Okamejei</i> Genus of cartilaginous fishes

Okamejei is a genus of small skates in the family Rajidae from the central and western Indo-Pacific, and the north-western Pacific Ocean.

<span class="mw-page-title-main">Graytail skate</span> Species of cartilaginous fish

The graytail skate, or gray tail skate, is a large species of skate in the family Arhynchobatidae, native to the south-western Atlantic Ocean and south-eastern Pacific Ocean. It is listed as endangered by the IUCN. It was caught as part of a commercial fishery around the Falkland Islands and is a bycatch in several other fisheries.

Bathyraja panthera, the leopard skate, is a species of cartilaginous fish in the family Arhynchobatidae. It was first described as a new species in 2011, having been discovered in the Aleutian Islands at depths between 50 and 258 m. It is a moderately large species with a short snout and wide mouth. The dorsal surface is pale greenish-brown, with speckling, round black spots and yellow blotches, giving it its specific name panthera from its resemblance to a leopard skin. It is an egg-bearing species, the eggs being enclosed in egg capsules with horns at the corners.

The longnose deep-sea skate is a large skate in the family Arhynchobatidae. It was first described in 1985 from specimens collected near New Zealand. It is known to be a deep-water skate, however lack of research trawls at depths past 1500 meters limits knowledge of the depths where the species can be found. The species is dark brown or grey, with an eponymous elongated snout. The species has been measured to be a maximum of 140 cm in total length, although size variation and growth patterns are not known.
