Phylum Chordata
Class Chondrichthyes

Genus Somniosus
Scientific Name S. longus


Male frog sharks are 3.6 ft long, while females are slightly longer at 4.3 ft. They have a short head and a blunt snout, and inside their mouth, one can see spear-like teeth in the upper jaw and semi-erect cusps on the lower one.

Where do they live

While the exact range of this shark remains unknown due to its rarity, all the captured specimens so far have been from the Pacific, suggesting it inhabits these waters. These sharks have been recorded across Chile, Japan, and New Zealand, in waters as shallow as 393-493 ft and as deep as 3661 ft.



These sharks are ovoviviparous, giving live birth to pups.


Its cylindrical, slender body makes it easier for this shark to swim.

Interactions with humans

As a deep-sea shark, very little remains known about it; currently, it isn’t considered a threat to humans.
