Think Sharks Are Scary? This Goliath Grouper Attack Is Terrifying

If you think sharks are the only scary things in the sea, you obviously haven't met the fish in this video.

While diving in 80-foot deep waters off the coast of Jupiter, Florida, spearfisherman Arif Sabir had a standoff with a seemingly fearless and ferocious goliath grouper, which GrindTV estimated was 300- to 400-pounds. Sabir had just caught a lesser amberjack with his spearfish gun, he told Grind TV, when he noticed the large grouper eyeing him and closing the distance in between them.

He was apparently "getting hunted by a goliath grouper," Sabir wrote on his YouTube page. The video, shot by his wife using a GoPro 3, shows the hefty fish as he nips at the man's flipper, tearing it off, and then goes straight for his catch with its powerful jaw. These sizable fish can pack at least three to five rows of sharp teeth in its lower jaw, according to the Florida Museum of Natural History.

The goliath grouper, which, according to FMNH, has been known to stalk humans and "conduct unsuccessful ambushes," took off with Sabir's spear and gun trailing behind. Fortunately, the diver was able to retrieve his equipment later.

"I've honestly never seen anything like that before," Sabir told GrindTV. But, even if the diver wasn't familiar with that specific size of this type of fish, goliath groupers have been known to roam western Atlantic waters near Florida.

Boy, are we glad these kinds of fish-on-human ambushes are few and far between!
