This is the swell shark they are carnivore creatures that dwell on the rocky seafloor of the pacific ocean. When threatened these guys will make an u shape of its body then swallow sea water to make itself look twice as big scaring off threats. In day they are usually harmless little creatures staying camouflaged on rocks. By night they dwell and eat fish or stay still with its mouth open for a fish to swim in. Sharks are cartilages which mean it has no bones which make these guys pretty flexible. These sharks lay leathery eggs that are causally mermaid purses. Depending on water temp. they could hatch in nine to twelve months.
