Shark Week is upon us, and that means insane new footage of sharks doing terrifying things.

This year’s coolest development — aside from Sharknado 2 — is the REMUS SharkCam, set up by the Woods Hole Oceanographic Institute. The SharkCam is actually six cameras mounted on what they call an “underwater vehicle” but which looks more like a steel torpedo.

The tech was designed to capture sharks in their native habitat, but it did a little more than that: It caught footage of a shark attacking it. The strikes, which come suddenly and out of nowhere, are heart-stopping, but they can’t help but leave you impressed with the speed and strength of these amazing predators.
