Trygonoptera ovalis, commonly known as the oval stingray, is a species of ray belonging to the family Urolophidae. This species is a fascinating example of marine biodiversity, exhibiting unique characteristics and playing a vital role in its ecosystem.
Description & Characteristics
Trygonoptera ovalis is a relatively small ray, with a maximum size of 61.0 cm. Its distinctive oval-shaped body distinguishes it from other ray species. The dorsal surface is a muted gray-brown, often marked with darker spots. This coloration provides effective camouflage, blending seamlessly with the seabed.
Habitat and Occurrence
Trygonoptera ovalis is primarily found in coastal waters, preferring depths ranging from 4.0 to 43.0 meters. This species is typically found in the neritic zone, the region of the ocean extending from the shoreline to the edge of the continental shelf. The neritic zone is characterized by its relatively shallow depth, allowing sunlight to penetrate and support a diverse array of life.
Taxonomy
Trygonoptera ovalis belongs to the class Elasmobranchii, which encompasses all sharks, rays, and skates. This species falls under the order Myliobatiformes, a group of rays known for their flattened bodies and gill openings located on their ventral surfaces. Trygonoptera ovalis is specifically categorized within the family Urolophidae, commonly known as the “stingrays” or “rough rays.”
Feeding
Trygonoptera ovalis is a carnivorous species, primarily feeding on a diet of benthic invertebrates such as crustaceans and polychaetes. It uses its sensory organs to detect prey buried in the sediment, employing its powerful jaws to crush and consume its meals.
