In the video above, you see two large grey creatures in the water. At first, they’re quite a distance away from the boat. But before long, one makes a turn and heads straight for the boat — ramming right into it.

The boat takes a hard roll but never flips over, which is lucky considering sperm whales can grow as large as 60 feet long, according to NOAA.
