Broadnose Sevengill Shark (Notorynchus cepedianus)

The Broadnose Sevengill Shark is the only extant member of its genus. Whereas most other sharks have 5 gill slits, sevengill sharks are recognisable because of its 7 gill slits.

Like many other fish, the shark uses counter shading as a of camouflage. Its dorsal surface is silvery grey in colour, which allows it to blend with the dark waters beneath it when viewed from above. Conversely, its ventral surface is light in colour, matching the sunlit surface when viewed from below.

An opportunistic predator, the broadnose sevengill preys on a great variety of animals. It has been found to feed on sharks, rays, chimaeras, cetaceans, pinnipeds, bony fishes, and carrion. These sharks occasionally hunt in packs to take down larger prey, using tactics such as stealth to succeed.

A FACT ABOUT SHARKS; This Broadnose Sevengill Shark lives at the Monterey Bay Aquarium in Monterey, California. It’s not a species of shark that many people know of. It’s actually the only extant member of the genus Notorynchus. Extant means surviving; so while there were others in the genus Notorynchus, they have all gone extinct. | Animal blog!
