Apristurus

The genus Apristurus comprises "demon cat sharks" and "ghost cat sharks," potentially making it the most diverse shark genus known, with up to 39 species. These sharks are part of the larger group known as cat sharks, which are small, mottled sharks found in tropical and temperate marine environments worldwide. Most cat sharks are less than 90 cm (3 feet) long and have slender bodies with elongated, cat-like eyes. They primarily feed on invertebrates and small fish and are not known to be aggressive towards humans. The genus Apristurus belongs to either the Scyliorhinidae or Pentanchidae families, depending on the classification system used.1
