Urolophus kapalensis is a species of ray in the family Urolophidae. It is a relatively small ray, reaching a maximum size of 43.3 cm. This species is found in the Indo-Pacific region, where it inhabits the benthic zone of coastal waters at depths ranging from 9.0 to 79.0 meters.
Description & Characteristics
Urolophus kapalensis is characterized by its relatively small size and flattened body shape, typical of rays. It has a broad, disc-shaped pectoral fin that extends to the head. The dorsal surface is covered in small, scattered denticles, while the ventral surface is smooth. Its tail is relatively short and slender, and it possesses a venomous spine located on the dorsal surface of the tail.
Habitat and Occurrence
Urolophus kapalensis is a demersal species, meaning it lives on or near the bottom of the ocean floor. Its preferred habitat is sandy and muddy bottoms in coastal waters, typically within the epipelagic and mesopelagic zones. This species is found primarily in the Indo-Pacific region, where it is relatively common in certain areas.
Taxonomy
Urolophus kapalensis belongs to the Class: Elasmobranchii, Order: Myliobatiformes, and Family: Urolophidae. This classification places it within the group of cartilaginous fishes, which includes sharks, rays, and skates. The Myliobatiformes order encompasses a diverse array of rays, including eagle rays, stingrays, and guitarfish. The Urolophidae family, known as the “stingrays,” contains numerous species characterized by their venomous spines and flattened body shape.
Feeding
Urolophus kapalensis is a carnivorous species that feeds primarily on small invertebrates like crustaceans, mollusks, and polychaetes. It uses its specialized jaws and teeth to crush and consume these prey items. The venomous spine located on its tail is used for defense against predators.
