Cruriraja is a genus of skates in the family Gurgesiellidae. [1] They are primarily found in the warm West Atlantic (including the Caribbean and Gulf of Mexico) and off southern Africa, but C. andamanica is from the Indian Ocean.
Anacanthobatis is a genus of smooth skates native to the western Indian Ocean, where found deeper than 200 m (660 ft).
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.
Raja, also known as raia, is a genus of skates in the family Rajidae containing 16 species. Formerly a wastebasket genus, many species historically categorized here have been moved to other genera in the family, such as Amblyraja, Beringraja, Dipturus, Leucoraja and Rostroraja. Raja are flat-bodied, cartilaginous fish with a rhombic shapes due to their large pectoral fins extending from or near from the snouts to the bases of their tails. Their sharp snouts are produced by a cranial projection of rostral cartilage. The mouth and gills are located on the underside of the body. They may be either solid-coloured or patterned, and most skates have spiny or thorn-like structures on the upper surface, while some species contain weak electrical organs within their tails. Mating typically occurs in the spring and the female lays numerous eggs per clutch which are encapsulated in leathery cases, commonly known as "mermaid’s purses". Species vary in size, ranging from about 40 to 140 cm (1.3–4.6 ft) in length. These bottom-dwellers are active during both day and night, and typically feed on molluscs, crustaceans and fish. Raja skates are found in the East Atlantic, also in the Mediterranean, and western Indian Ocean, ranging from relatively shallow water to a depth of 800 m (2,600 ft). Skates and related species have fossil records dating from the Upper Cretaceous period, thus this well-adapted species is quite ancient.
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.
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.
Breviraja, commonly known as lightnose skates, is a genus of small skates in the family Rajidae. They are found in deep water of the western Atlantic, including the Gulf of Mexico.
Dactylobatus is a genus of skates in the family Rajidae. They are found in deep waters in the western Atlantic Ocean from Brazil to the United States, including the Gulf of Mexico.
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.
Dipturus teevani, commonly known as the prickly brown ray or Caribbean skate, is a species of cartilaginous fish in the family Rajidae. The prickly brown ray is medium in size compared to other skates, and is known from a patchy, deep-water distribution in the western Atlantic Ocean.
Pygmy skates are cartilaginous fish belonging to the family Gurgesiellidae in the superorder Batoidea of rays. Nineteen species in three genera are known.
The Melbourne skate is a species of fish in the belonging to the skate family Rajidae. It is endemic to southern Australia. Its natural habitat is open seas. It is found at depths up to 345 meters.
The panrays are a genus, Zanobatus, of rays found in coastal parts of the warm East Atlantic Ocean, ranging from Morocco to Angola. It is the only genus in the family Zanobatidae, which traditionally has been included in the Myliobatiformes order, but based on genetic evidence it is now in Rhinopristiformes or a sister taxon to Rhinopristiformes.
