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.

Arhynchobatidae
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. Genera The 13 recognized genera of softnose skates are: * '' Arhynchobatis'' * '' Atlantoraja'' * ''Bathyraja'' * '' Brochiraja'' * '' Insentiraja'' * '' Irolita'' * '' Notoraja'' * ''Pavoraja'' * ''Psammobatis'' * ''Pseudoraja'' * '' Rhinoraja'' * ''Rioraja The Rio skate (''Rioraja agassizii'') is a shallow water skate native to the Atlantic coast of South America from Brazil to southern Argentina.
