Raja radula, also known as the Raja radula, is a species of skate belonging to the family Rajidae. It is a relatively small skate, reaching a maximum size of 70.0 cm.
Description & Characteristics
Raja radula is characterized by its distinctive physical attributes, including a flattened body with a broad, diamond-shaped disc. The skate has a pointed snout and large, pectoral fins that extend around the body. Its dorsal surface is typically a mottled brown or gray color, while the ventral surface is white.
Habitat and Occurrence
Raja radula is a demersal species, meaning it lives on the seabed. It is found in the northeastern Atlantic Ocean, primarily in the waters off the coast of Europe. The skate is commonly found in the continental shelf and slope areas, typically inhabiting depths between 200-600 meters. This depth range places it in the bathyal zone, a marine zone characterized by dim light and low temperatures.
Taxonomy
Raja radula belongs to the Class: Elasmobranchii, Order: Rajiformes, and Family: Rajidae. The Class Elasmobranchii encompasses cartilaginous fishes, which include sharks, rays, and skates. The Order Rajiformes contains skates and rays, characterized by their flattened bodies and enlarged pectoral fins. The Family Rajidae consists of skates, a group of fish with a primarily benthic lifestyle.
Feeding
Raja radula is a carnivorous fish that feeds on a variety of invertebrates, including crustaceans, mollusks, and worms. It uses its flattened body and pectoral fins to maneuver across the seabed, searching for prey. The skate has a mouth located on the ventral side of its body, equipped with rows of small, sharp teeth that are adapted for crushing and grinding its food.
