_Dipturus chilensis_, commonly known as the Chilean skate, is a species of ray in the family Rajidae. This skate is found in the southeastern Pacific Ocean, where it inhabits the continental shelf and slope.
Description & Characteristics
_Dipturus chilensis_ is a large skate, reaching a maximum size of 152.0 cm in length. It has a characteristic flattened body shape typical of skates, with a broad, disc-shaped pectoral fin that extends around the head. Its dorsal surface is covered in small, rough scales, and its ventral surface is smooth. The skate’s coloration varies, but it generally displays a brownish-grey to dark grey color, often with darker blotches or spots.
Habitat and Occurrence
_Dipturus chilensis_ is found in the southeastern Pacific Ocean, off the coasts of Chile and Argentina. It typically inhabits depths ranging from 100 to 1,000 meters, making it a prevalent presence in the bathyal zone, also known as the mid-water zone. This skate is known to occur on both the continental shelf and slope, where it utilizes the diverse benthic environments for foraging and reproduction.
Taxonomy
_Dipturus chilensis_ belongs to the Class: Elasmobranchii, which includes all sharks, rays, and chimaeras. It is further classified within the Order: Rajiformes, which encompasses the skates and their close relatives. Finally, it is a member of the Family: Rajidae, a diverse family containing over 200 species of skates.
Feeding
_Dipturus chilensis_ is a carnivorous species that primarily feeds on benthic invertebrates, such as crustaceans, mollusks, and polychaete worms. It uses its flattened body and sharp teeth to locate and consume prey on the seabed. The skate’s diet reflects its adaptation to the benthic environment and its role as a predator within its ecosystem.
