Groupers are known to grown to some enormous sizes.
In September 2010, a Costa Rican newspaper reported a 2.3-m (7.5-ft) grouper in Cieneguita, Limón. The weight of the fish was 250 kg (550 lb) and it was lured using one kilogram of bait.
In November 2013, a 310-kg (686-lb) grouper had been caught and sold to a hotel in Dongyuan, China.
In August 2014 off Bonita Springs in Florida (USA) a big grouper took in one gulp a 4-foot shark which an angler had caught.
