While on a spearfishing adventure this summer, a diver got way more than he bargained for.

Chris Coates was filming his experience with another diver in the South Atlantic Ocean, off the coast of Ascension Island, when all of a sudden a whale shark smashes right into him!

As you can see in the video above, his friend tried to warn him before the incoming surprise.

Coates says he took most of the impact on his lower torso and was hit in the head by the whale shark’s dorsal fin, according to newsflare.

Whale sharks are a slow-moving filter-feeding shark that eat smaller food like plankton and squid.

Maybe the shark just couldn’t stop itself fast enough?
