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.

Irolita
''Irolita'' is a genus of softnose skates in the family Arhynchobatidae, commonly known as round skates. There are two species, both endemic to Australia, found over soft bottoms on the outer continental shelves and upper continental slopes, at depths of 50–200 m for the southern round skate and 142–209 m for the western round skate. The distributions of the two species do not overlap.

The nasal flaps are merged into a well-developed, bilobed nasal curtain forward of the mouth. The jaws are slightly arched with the upper teeth exposed. The teeth are sexually dimorphic; those of adult males are spear-shaped with long, sharp cusps, while those of fem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rajiformes
Rajiformes is one of the four orders in the superorder Batoidea, flattened cartilaginous fishes related to sharks. Rajiforms are distinguished by the presence of greatly enlarged pectoral fins, which reach as far forward as the sides of the head, with a generally flattened body. The undulatory pectoral fin motion diagnostic to this taxon is known as rajiform locomotion. The eyes and spiracles are located on the upper surface of the head and the gill slits are on the underside of the body. Most species give birth to live young, although some lay eggs enclosed in a horny capsule ("mermaid's purse"). Characteristics Rajoids typically have a dorsoventrally flattened body. The snout is slender and pointed and the wide mouth, often covered with a fleshy nasal flap, is on the underside of the head. The eyes and well-developed spiracles are located on the top of the head. In most species, the spiracles are large and are the main means of drawing water in for respiration. There is no n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spotback Skate
The spotback skate (''Atlantoraja castelnaui'') is a species of fish in the family Arhynchobatidae. It is found off the Atlantic coasts of Argentina, Brazil, and Uruguay where its natural habitat is over the continental shelf in the open sea. It is a large fish, growing to over a metre in length. It feeds mainly on other fish according to availability, with shrimps, octopuses and other invertebrates also being eaten. Reproduction takes place throughout most of the year, with the eggs being laid in capsules that adhere to the seabed. The spotback skate is the subject of a fishery and is thought to be overfished, resulting in Greenpeace adding the fish to its red list of fish to be avoided, and the International Union for Conservation of Nature listing it as an "endangered species". Distribution The ''Atlantoraja castelnaui'' are found in the Southwest South Atlantic Ocean from Rio de Janeiro State in Brazil to Argentina. They prefer warm-temperate waters at depths ranging from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bathyraja Abyssicola
The deepsea skate (''Bathyraja abyssicola'') is a species of softnose skate, in the family Arhynchobatidae, found in deep water from 362 to 2,906 m, usually on the continental slope. They are distributed from off northern Baja California around Coronado Island and Cortes Bank, north to the Bering Sea, and west to Japan. There have also been sightings north of Darwin Island within the Galapagos Marine Reserve in 2015. This was the first record of the Deepsea Skate being found in the tropical eastern Pacific Ocean. It is fairly common below 1,000 m, and is taken as bycatch in deepwater trawls and traps. The species name ''abyssicola'' comes from the Greek ''abyssos'' meaning "bottomless", and ''cola'' meaning "living at depths". The pectoral fin disc of the deepsea skate has a moderately triangular anterior margin, a broadly rounded posterior margin, and rounded tips. The disc is slightly wider than it is long. One to five nuchal thorns are placed on the dorsal midline behind t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
