While reeling in a 3-foot shark last week, a Florida fisherman helplessly watched as his catch was devoured by a massive 500-pound Goliath grouper.The snatch and grab occurred just off the coast of Everglades City, Florida, during a charter with Everglades Fishing Company."That same grouper later swallowed a stingray — or manta ray," said Michelle Wheeler of Everglades Fishing Company to Fox News . "[Goliath groupers] have become a nuisance, according to a lot of fishermen. They're eating everything." According to Fox, the Fiat-sized fish eventually spit the shark back out. Goliath groupers are considered a protected species in the state of Florida, and can grow up to 8 feet long and weigh up to 800 pounds.
