Rostroraja Alba
The bottlenose skate, spearnose skate, or white skate (''Rostroraja alba'') is a species of skate in the family Rajidae. It is a benthic fish native to the coastal eastern Atlantic Ocean. Due to overfishing, it has been depleted or extirpated in many parts of its former range in the northeastern Atlantic and the Mediterranean Sea, and is now endangered. Distribution and habitat The bottlenose skate is found along the coastlines of the eastern Atlantic Ocean, from the southern British Isles to South Africa and extends into the southwestern Indian Ocean to Mozambique. It is present as well in the western and northeastern sectors of the Mediterranean Sea. It is a benthic species of sandy and detrital bottoms, at depths of 40–400 m (exceptionally down to 500 m) from coastal regions to the upper continental slope. (1974) reported that it is more prevalent in rocky habitats. Description Most bottlenose skates are 60–150 cm long, with maximum recorded lengths of 230 cm ...

Rostroraja Texana
The roundel skate or Texas clearnose skate (''Rostroraja texana'') is a species of cartilaginous fish in the family Rajidae. It is found in the Gulf of Mexico, Southeast Florida and the Yucatan Peninsula. Description The disc of the roundel skate is diamond-shaped. The short rounded snout has a clear area of skin on either side. The rest of the dorsal surface is an unblotched chocolate brown colour, although sometimes there are darker patches. A pair of distinctive dark eyespots with pale pink rims lie on either side of the middle of the dorsal surface (these may confuse potential predators). A row of thorns runs along the midline of the back, but there are no venomous spines. The medium-length tail has a short dorsal fin near its tip and a small caudal fin. Males become mature at about 5 years old at a length of about , while females are mature a year later at a length of about .

Rostroraja Eglanteria
The clearnose skate (''Rostroraja eglanteria'') is a species of cartilaginous fish in the family Rajidae. ''R. eglanteria'' is also known by other common names such as the brier skate and summer skate. Clearnose skates are easily identified by the translucent patches on either side of their snouts and their mottled dorsal surface. They are found along the Atlantic and Gulf coasts of the United States in shallow waters of the continental shelf. Taxonomy Clearnose skates are elasmobranchs in the order Rajiformes and family Rajidae. They were one of nearly thirty members of the genus ''Raja'' before redesignation based on DNA analysis in 2016. Clearnose skates were first described as ''Raja eglanteria'' by Bosc in 1800. Other scientific names include ''R. chantenay'', ''R. desmarestia,'' and ''R. diaphanes;'' however, these names rarely appear in the literature.

Skate (fish)
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.LAST, P.R. & SÉRET, B. & STEHMANN, M.F.W. & WEIGMANN, S. (2016) Skates, Family Rajidae.

CSIRO Publishing, Melbourne: 204–363 Softnose skates and pygmy skates were previously treated as subfamilies of Rajidae (Arhynchobatinae and Gurgesiellinae), but are now considered as distinct families. Alternatively, the name "skate" is used to refer to the entire order of Rajiformes (families Anacanthobatidae, Arhynchobatidae, Gurgesiellidae and Rajidae). Members of Rajidae are distinguished by a stiff snout and a rostrum that is not reduced. Taxonomy and systematics Evolution Skates belong to the ancient lineage of cartilaginous fishes.

Raja (fish)
''Raja'', also known as ''raia'', is a genus of Skate (fish), skates in the family (biology), family Rajidae containing 16 species. Formerly a wastebasket genus, many species historically placed 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 nearly 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 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, and some species contain weak electrical organs within their tails. Mating typically occurs in the spring and the female lays numerous Egg (biology), eggs per clutch which are encapsulated in leathery cases, commonly known as "Egg cas ...
