It was enough to make even the shark expert himself jump backward a bit.

State biologist Greg Skomal got an up-close look at a great white shark during a recent excursion off Cape Cod when one of the apex predators that researchers had been observing breached the water right beneath him, exposing its large teeth.

“Did you see that?! Did you see that?!” Skomal can be heard saying in a video posted by the Atlantic White Shark Conservancy Monday morning. “It came right up, and opened its mouth right at my feet!”

In the video, Skomal can be seen standing on the research boat’s pulpit, as the captain closes in on a shark. Skomal was using a long pole with a GoPro camera attached at the end so he could dip it into the water and capture footage of the shark. That’s when it suddenly breached the ocean’s surface.
