The sevengill cow shark ... it's a strange name for a strange species. Our dive crew goes in search of the most primitive of all the shark species -- an elusive underwater predator whose skeleton still closely resembles that of its prehistoric ancestors.

Hi, thanks for watching. Sevengill cow sharks are pretty opportunistic hunters and have been known to eat almost anything from dolphins and seals to porpoises and rays. Typically they feed on large fish species, crustaceans and carrion.

Thanks for the comment (and the compliment), Avonnye. It is believed that sevengill sharks stalk their prey from behind and then rapidly burst forward when going in for the kill ... so your theory sounds about right!

I thought besides the number of gills the tail of this shark was pretty distinctive as a feature. Beautiful creatures.

They probably don't have a very civilized approached to hunting, since they kept bumping into the camera. They might hunt by using the simple short burst of speed to quickly bite there and kill there prey. But that might be unlikely cause of there small fins, most likely built for a long drawn out chase then a speedy one.There long tail fin might help them put on a burst of speed when closing in for the kill. but anyway this was a good video I really like it good job

Lol I bet these sharks are sneaky bastards, one look and people think "harmless" then the next minute he's taken a chunk out of you, maybe they lul their prey into complacency. Seems to me they are built for marathon not sprint like some other sharks, their front fins seem to have a slight upturn, and they are much more bulletlike/or eel like in structure. I still wouldn't turn my back on these guys. Good filmaking
