Do Sharks Hunt Cooperatively? | Shark Attack Files

In a remote atoll near Tahiti, Corey Garza, Andy Casagrande, and safety diver Perrick Seibold put themselves in the line of fire. These investigators test the theory that some tiger sharks may work together and hunt in packs. Before they know it, they're fending off a double approach by two large tiger sharks and more, again and again. The sharks seem to come in waves; it's too much. They must retreat.

Insane moments on that camera! I saw you deflecting one coming here, another one behind you, and then at one point you and Perrick literally like dancing on tigers. That was crazy! You see what I mean now? How they don't disappear, and then as if there's like one coming, it's boom, all at once. Here we go; 360 tiger sharks!

They review the footage and search for clues. If these tigers cooperatively hunt, it may suggest that great whites could also do the same.

Oh wow, wow! Okay, one, two, three—three tigers. There are three right there, and then another tiger!

After careful review, Corey is convinced; tiger sharks working together makes sense. It's better for them and easier for them to learn to cooperate rather than to spend their whole time fighting each other. It could be an anomaly unique to this species, except for emerging evidence from around the world.

From sand tiger sharks off South Africa to lemon sharks in Australia and gray reefs in French Polynesia, they've all been observed to seemingly work together. And now this for the tigers of Tahiti: this 360 shows us that all of the sharks in mass are showing up together and leaving together pretty much every single time. This is not—this isn't coincidence! Yeah, because it's happening every single time.
