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.
We just released a healthy sevengill shark into the bay. She was on exhibit for a year, gaining 2.5 inches and 14.5 pounds! This rotation of sevengills through our exhibit is great for shark fans—and shark conservation. By displaying, tagging and releasing these beautiful animals, we’re learning more about sharks and what can be done to save them.
Went SCUBA diving in the shark tank for the first time. My friend snapped a picture of me while I was cleaning the acrylic. The first thing they told me when I got in was “The sharks have the right of way, so stay back.”
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!
