Maybe your mother told you never to eat anything bigger than your head, but apparently this goliath grouper never got the memo. A YouTube video uploaded by user Gimbb14 shows the massive fish swallowing a 4-foot shark whole off Florida's Gulf Coast.
In a reddit post, Gimbb14 describes the events that led to the video:
Ran out to the reef at around 8am yesterday and wasn't having much luck. Put out a chum block, set down some blue runners on the reef and waited. Had a 15lb goliath grouper take and brought him up, as I brought him to the boat, the monster goliath shown in the video came and tried to steal him. About 30 minutes later I had about a 5foot nurse shark take and brought him up. As I was dehooking the shark, the goliath came back and inspected but didn't attack him. Finally, about an hour after the nurse shark, I hooked the black tip [shark] behind the boat in the chum slick, and then the hilarity in the video began.
Goliath groupers are critically endangered, according to the Florida Museum of Natural History, with the population slashed by 80 percent over the last 10 years.
