Undersea, humans are out of their element, but that hasn’t kept us from going there.

We don’t know much about this video except it’s a pretty cool 30 seconds involving a spear-fisherman, his prey and a large grouper looking for an easy meal.

One video viewer said the hungry hunter is a potato grouper, or potato cod, native to Australia, which would put this clip in the waters of southern Asia.

Grouper can reach a length of 8-1/2 feet and weigh as much as 240 pounds, and although they are considered harmless to humans, some of the larger fish can be aggressive, as we see.
