False Catsharks [Pseudotriakis]

Description

Pseudotriakis is a genus within the family Pseudotriakidae, commonly referred to as the false catsharks. This genus is known for its deep-sea dwelling sharks, which are characterized by their broad, blunt snouts, long caudal fins, and soft, flabby bodies. These sharks are typically found in temperate and tropical oceans around the world, usually in deep waters. The genus Pseudotriakis is distinctive for its reproductive strategy, where it is believed to have a low reproductive rate with possibly ovoviviparous (live-bearing) mode without a yolk-sac placenta, a trait that is unusual among sharks. Their diet likely consists of a variety of deep-sea fish and invertebrates. Despite their large size, with the false catshark (Pseudotriakis microdon) reaching lengths of up to 3 meters, they are not considered a threat to humans due to their deep-sea habitat and rare encounters.
