Do Groupers Attack Humans

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

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. 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.

I learned about it from a buddy diver who excitedly told me to go diving with him upon a prompt from a classmate in high school who happened to be the mayor of that town. Probably, I am lucky that the Goliath grouper (Epimetheus quinquefasciatus) I encountered several minutes when I plunged into the water was still a juvenile.

I brought with me my automatic Nikon camera encased in a plastic casing to make it water-resistant as taking pictures is a pleasure for me each time I travel. I grabbed the camera hanging by a tough nylon string around my wrist, and took a video of the Goliath grouper following my buddy.

Despite the huge size of the Goliath grouper, they seem to be docile fishes although there are reports that they doattackhumans. I saw one video that says so but analyzing the situation, I thought the reason was mainly to feed, not really to attack.

The moving fins attracted the grouper thinking probably that it was its prey and snapped on it. When the juveniles are older, they migrate to the coral reefs and stay there for more than 40 years.

Life cycle of the Goliath grouper (Illustration by Jane Hakka, IAN Image Library (ian.umces.edu/imagelibrary/) The nearshore environment is a fragile one that should be protected or conserved considering the highly complex life that intertwine in mangrove ecosystems.

The Goliath grouper is only one of the rich diversity of life that support man. About The Author Regional, Patrick Dr. Patrick A.

Grouper Malabar grouper, Epimetheus malarious Scientific classification Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Performed Family: Serranidae Subfamily: EpinephelinaeBleeker, 1874 Tribes and genera Not all errands are called groupers '; the family also includes the sea basses.

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.

Groupers are Telecasts, typically having a stout body and a large mouth. They can be quite large, and lengths over a meter and the largest is the Atlantic Goliath grouper (Epimetheus Tamara) which has been weighed at 399 kilograms (880 pounds) and a length of 2.43 m (7 ft 11 1 2 in), though 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. They habitually eat fish, octopuses, and crustaceans.

Reports of fatal attacks on humans by the largest species, such as 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.

The word “grouper” is from the Portuguese name, group, which has been speculated to come 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. The species in the tribes Grammistini and Diploprionini secrete a mucus like toxin in their skin called Rammstein and when they are confined in a restricted space and subjected to stress the mucus produces a foam which is toxic to nearby fish, these fishes are often called soap fishes.

The largest males often control harems containing three to 15 females. Groupers often pair spawn, which enables large males to competitively exclude smaller males from reproducing.

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.

Both group spawning and habitat cover increase the likelihood of a smaller male to reproduce in the presence of large males. 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. Many groupers are important food fish, and some of them are now farmed.

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. In September 2010, a Costa Rican newspaper reported a 2.3 m (7 ft 7 in) 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 (680 lb) grouper had been caught and sold to a hotel in Dong yuan, China.
