Pseudotriakis

Pseudotriakis is a genus of ground sharks in the family Pseudotriakidae. This genus contains a single, poorly known species, Pseudotriakis microdon. The common name for this species is the false catshark. These sharks are found in deep waters across the world's oceans, typically at depths ranging from 500 to 1,400 meters. They inhabit both continental slopes and island shelves.

Pseudotriakis microdon is characterized by its elongated, slender body and a broad, flattened head. They possess two large dorsal fins set far back on the body, and a long, low anal fin. Their coloration is generally dark brown or grey, often with a lighter underside. Information regarding their diet is limited, but it is believed to consist of deep-sea fishes, cephalopods, and crustaceans. They are ovoviviparous, meaning the eggs hatch inside the mother's body before the pups are born live. Due to their deep-sea habitat and infrequent sightings, much about their behavior, reproductive biology, and population status remains unknown. They are not considered a commercially important species.
