Dipturus lamillai is a species of ray, belonging to the family Rajidae. It is a fascinating creature that inhabits the depths of the ocean, with a unique appearance and intriguing life history.
Description & Characteristics
Dipturus lamillai is a relatively large ray, reaching a maximum size of 94.2 cm. Its body is flattened, with a wide, disc-shaped pectoral fin that extends around its head and forms a continuous, wing-like structure. The ray’s body is covered in small, rough denticles, giving it a sandpaper-like texture. Its eyes are located on the dorsal side of the head, and its nostrils are positioned just below the eyes. Dipturus lamillai has a long, whip-like tail that extends well beyond the disc, with a single dorsal fin and a small caudal fin. The coloration of Dipturus lamillai varies depending on its habitat, but typically ranges from brownish to grayish, often with darker markings.
Habitat and Occurrence
Dipturus lamillai is a deep-water ray, typically found at depths ranging from 162.0 to 515.0 meters. This species is considered a bathypelagic inhabitant, meaning it lives in the midwater zone of the open ocean, well away from the seabed. This marine zone is characterized by low light levels and cold temperatures, providing a unique environment for Dipturus lamillai to thrive.
Taxonomy
Dipturus lamillai is classified within the Class Elasmobranchii, which includes all sharks, rays, and skates. This species belongs to the Order Rajiformes, a group that encompasses all skates and rays. Dipturus lamillai is further categorized within the Family Rajidae, which is a diverse family of skates that are found worldwide.
Feeding
Dipturus lamillai is a carnivorous ray, feeding primarily on benthic invertebrates such as crustaceans, mollusks, and polychaete worms. It uses its specialized dentition to crush and grind its prey, effectively extracting nutrients from its food. The ray’s flattened body and large pectoral fins allow it to maneuver easily along the seabed, effectively searching for food and avoiding predators.
