The frog shark (Somniosus longus) is a very rare species of shark mainly found in deep water. It is in the sleeper shark family with the Greenland shark.

Description[edit]

The frog shark is known to grow to at least 143 cm in length.[1]

Range[edit]

Fewer than a dozen specimens of this deepwater shark have been collected, mostly from the Pacific Ocean. The frog shark has been recorded off the coasts of Japan, New Zealand, and possibly Salas y Gómez, as well as the Nazca Ridge, from as shallow as 120–150 m and as deep as 1,116 m.[1]

Threats[edit]

The frog shark is occasionally caught by trawl, longline, and crab-pot fisheries. As of 2015, no current conservation efforts are in place.[1]
