Reaching up to 10 feet and as much as 800 pounds, the goliath grouper is one fish that demands respect. In some cases, it also demands food. The video below, reportedly recorded off the coast of Jupiter, Florida, shows a grouper confronting a group of spearfishers over their harvest. Impatient with the slowness of their tribute, the grouper shucks one diver of a fin and quickly uses the distraction to steal his fish. The problem is, the grouper also snared the speargun with it.
The gun was eventually found a quarter mile away buried in sand.
