Description & Characteristics
The Oxynotus centrina is a relatively small shark, reaching a maximum size of 150.0 cm. It possesses a distinctive body shape with a long, slender snout and a compressed, angular head. The shark’s body is covered in rough, prickly scales, giving it its common name. Its color can range from dark gray to brown, with lighter spots scattered across its body.

They are commonly found in the northeastern Atlantic Ocean, including the waters around the British Isles, Norway, and the Mediterranean Sea. Oxynotus centrina typically inhabit the bathypelagic zone, a region of the ocean between 1000 and 4000 meters deep. They are well-suited to life in these dark and cold environments, with their specialized physiology allowing them to survive in low oxygen conditions.
