When a group of fishermen was fishing of Bonita Springs, Florida, one August day, they were thrilled to snag a black-tip shark on their line. Out of the depths of the sea, a monstrous fish appeared, snatched the shark off the hook and ate it in a single bite.
The footage shows the whole amazing scene, and it was later used to identify the large fish as a goliathgrouper. The Atlantic goliathgrouper (also known as the “Jewish”), like most groupers, is an ambush predator and eats fairly large fishes and invertebrates and even small sharks.
The total weight of the boat hull is 550lbs, so we needed to find one of the largest Goliath Groupers in all of Florida to break this number. We started the day off fishing for bonito (false albacore).
I found this YouTube video to be cool. I am not sure if you let us post fish related videos you find on YouTube here (if you don't I am sorry), but the grouper eating the shark is cool and I wanted to show it to people who appreciate fish.
It's not unrelated at all, the goliathgrouper Epimetheus Tamara and what looks like a young lemon shark Negation brevirostis are both North American natives with really large distributions.

A pity I cannot find the clip from Extreme Contact (a show that used to be on animal planet) where the guy diving tried toughing a Goliath groups and had his arm swallowed and had to struggle to the surface with a 400 pound fish on his arm, that was impressive. I'd like to see someone with a saltwater tank big enough to house a fully grown Goliath. I don't know my salt water fish very well but I think these are two different species of large grouper.

The common name grouper is usually given to fish in one of two large genera : Epimetheus and Mycteroperca. In addition, the species classified in the small genera Hyperion, Completes, Dermatologist, Graciela, Scotia, and Trio are also called groupers.
However, some hamlets (genus Affected), the hinds (genus Cephalopods), the lyre tails (genus Various) and some other small genera (Gonioplectrus, Nippon, Paranoia) are also in this subfamily, and occasional species in other serrated genera have common names involving the word grouper “. Nonetheless, the word grouper on its own is usually taken as meaning the subfamily Epinephrine.
The origin of this name in Portuguese is believed to be from an indigenous South American language. In New Zealand, “groper” refers to a type of wreck fish, Poly prion oxygenate, which goes by the Mori name haiku.
In the Middle East, the fish is known as hammer, and is widely eaten, especially in the Persian Gulf region. Groupers are telecasts, typically having a stout body and a large mouth.
They can be quite large, and lengths over a meter and weights up to 100 kg are not uncommon , though obviously in such a large group, species vary considerably. They do not have many teeth on the edges of their jaws, but they have heavy crushing tooth plates inside the pharynx.
Reports of fatal attacks on humans by the largest species, the giant grouper (Epimetheus lanceolatus) are unconfirmed. They also use their mouths to dig into sand to form their shelters under big rocks, jetting it out through their gills.
As such, if a small female grouper were to change sex before it could control a harem as a male, its fitness would decrease. If no male is available, the largest female that can increase fitness by changing sex will do so.
Gonochorism, or a reproductive strategy with two distinct sexes, has evolved independently in groupers at least five times. The evolution of gonochorism is linked to group spawning high amounts of habitat cover.
Fitness of male groupers in environments where competitive exclusion of smaller males is not possible is correlated with sperm production and thus testicle size. Gonochoristic groupers have larger testes than protogynous groupers (10% of body mass compared to 1% of body mass), indicating the evolution of gonochorism increased male grouper fitness in environments where large males were unable to competitively exclude small males from reproducing.
Unlike most other fish species which are chilled or frozen, groupers are usually sold live in markets. Groupers are commonly reported as a source of Ciguatera fish poisoning.
DNA barcoding of grouper species might help in controlling Ciguatera fish poisoning since fish are easily identified, even from meal remnants, with molecular tools. Malaysian newspaper The Star reported a 180-kg grouper being caught off the waters near Play Serbian in the Straits of Malacca in January 2008.
Shenzhen News in China reported that a 1.8-m grouper swallowed a 1.0-m white tip reef shark at the Fuzhou Sea World aquarium. 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 Dong yuan, China.
