Notoraja is a genus of skates in the family Arhynchobatidae. They are found in deep water in the Indian and western Pacific Oceans. [2]
There are currently 15 recognized species in this genus: [2]
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.
Apristurus is a genus of catsharks, the family Scyliorhinidae, commonly known as the ghost or demon catsharks.
Etmopterus is a genus of lantern sharks in the squaliform family Etmopteridae. They are found in deep sea ecosystems of the Atlantic, Indian and Pacific Oceans.
Bathyraja is a large genus of skates in the family Arhynchobatidae.
Dipturus is a large genus of skates native to the Pacific, Atlantic, and Indian Oceans. They were formerly included in Raja. Some species initially moved to Dipturus were later placed in Dentiraja, Spiniraja, and Zearaja.
Bythaelurus is a genus of deep-water catsharks and part of the family Scyliorhinidae. The genus Bythaelurus Compagno 1988 was first described as a subgenus of Halaelurus Gill 1862 based on several morphological characteristics including a soft body with thin skin, a bluntly rounded snout without a pointed, knob-like tip, and eyes not noticeably elevated on the dorsal surface of the head. Members of this genus are generally found in deep water and have more somber body coloration.
Gurgesiella is a genus of fish in the family Gurgesiellidae. These relatively small deep-water skates are found in the Atlantic and Pacific Oceans off South and Central America.
Leucoraja is a genus of hardnose skates in the family Rajidae, commonly known as the rough skates. They occur mostly on continental shelves and slopes in the north-western and eastern Atlantic Ocean, the Mediterranean Sea, the south-western Indian Ocean, and Australia.
Neoraja is a genus of fish in the family Rajidae found in the Atlantic Ocean. These small, deep-water skates all reach a total length of approximately 30 centimetres (12 in).
Rajella is a genus of skate found deeper than 150 m (490 ft) in the Pacific, Atlantic and Indian oceans.
Rostroraja is a genus of skate belonging to the family Rajidae, native to the Atlantic Ocean and East Pacific, including the Mediterranean, Caribbean, Gulf of Mexico and Gulf of California. The genus was considered monotypic in the past, but a number of species usually classified in Raja have been reassigned to this genus based on genetic analysis.
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.
Springeria folirostris, the leaf-nose leg skate, is a species of ray in the family Anacanthobatidae, native to depths of 300–510 m (980–1,670 ft) in the Gulf of Mexico. It was originally described in the genus Springeria, but this was later considered a subgenus of Anacanthobatis. In 2016 Springeria was again elevated to full genus status.
Cruriraja is a genus of skates in the family Gurgesiellidae. They are primarily found in the warm West Atlantic and off southern Africa, but C. andamanica is from the Indian Ocean.
Fenestraja is a genus of eight species of skate in the family Gurgesiellidae. They are found in deeper waters of the western Atlantic and the Indian Ocean.
Brochiraja is a genus of deep-sea skates in the family Arhynchobatidae containing eight species. They are found in the waters around New Zealand and the Tasman Sea.
Okamejei is a genus of small skates in the family Rajidae from the central and western Indo-Pacific, and the north-western Pacific Ocean.
Sinobatis is a genus of rays in the family Anacanthobatidae native to deep water in the Indo-Pacific Ocean.
Pygmy skates are cartilaginous fish belonging to the family Gurgesiellidae in the superorder Batoidea of rays. Nineteen species in three genera are known.
