Sinobatis is a genus of rays in the family Anacanthobatidae native to deep water in the Indo-Pacific Ocean. [1]
Nine recognized species are in this genus:
The Anacanthobatidae, the smooth skates or leg skates, are a family of skates found at depths below 200 m (660 ft) in the Indian, Pacific and Atlantic Oceans.
Anacanthobatis is a genus of smooth skates native to the western Indian Ocean, where found deeper than 200 m (660 ft).
Apristurus is a genus of catsharks, the family Scyliorhinidae, commonly known as the ghost or demon catsharks.
The Pseudotriakidae are a small family of ground sharks, belonging to the order Carcharhiniformes, containing the false catsharks and gollumsharks. It contains the only ground shark species that exhibit intrauterine oophagy, in which developing fetuses are nourished by eggs produced by their mother.
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.
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.
Notoraja is a genus of skates in the family Arhynchobatidae. They are found in deep water in the Indian and western Pacific Ocean.
The black legskate is a species of smooth skate native to the Indian Ocean off of Madagascar and Mozambique. It is the only species in the monotypic genus Indobatis. It inhabits the continental slope at depths of from 1,000 to 1,725 metres. This species can reach a length of 21 centimetres (8.3 in). It is dark-colored, greyish-black or brownish on the dorsum, ventrally lighter.
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.
Hydrolagus is a genus of fish in the family Chimaeridae found in the Atlantic, Indian and Pacific Oceans.
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 and is 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.
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.
Okamejei is a genus of small skates in the family Rajidae from the central and western Indo-Pacific, and the north-western Pacific Ocean.
The dwarf false catshark is a species of ground shark, which lives in the Indian Ocean near Socotra. This species is one of two known members of its genus, the other being the pygmy false catshark off the coast of India, Sri Lanka, and the Maldives.The pygmy false catshark is very closely related to the dwarf false catshark, but has some morphological differences. Two examples are its absence of an oral papillae and that it has more tooth rows in the lower jaw.
The pygmy false catshark, also known as the eastern dwarf false catshark is a species of ground shark, which lives in the Indian Ocean near Kochi, Kerala and off Sri Lanka. This species is one of two known members of its genus, the other being the dwarf false catshark which also lives in the Indian Ocean, but near Socotra. This had prior been an uncategorized species, but was recognized as a new species in 2019.
