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.

The Hammerhead usually feeds on smaller sharks like the Blacktop (Image: GETTY)Mr O’Neill said the Grouper was around 200 to 300 pounds heavy, and is normally found on the ocean floor. Gases in the Grouper ’s stomach expands causing it to bloat and float on the surface, making them the perfect meal for predators.

# of Dives: 500 – 999 Location: Metro New York As far as I know groupers are only dangerous if you eat them. Large groupers in the Caribbean are linked to increased risk of Cautery poisoning.
In my limited experience the most aggressive fishes I've run into are spade fish, Bermuda chubby and of course damsel fishes, which are more annoying than dangerous. # of Dives: 100 – 199 Location: Tampa Florida While fishing down in the keys a buddy of mine was reeling in a 30 0r so inch grouper, right at the boat a Cuba took a bite of it, before the Cuba wished away with its free meal a much larger grouper nailed it on its side at a very high rate of speed.

VS England beat Australia by 6 wickets Full Scorecard Halfway through the afternoon, while beach combing on a nearby moth, all hell broke loose as we were both overcome by terrible stomach cramps.
By the time we got back to the boat, other symptoms were telling me clearly that after thirty years of catching and eating tropical fish, I was now on the receiving end. We chose to deal with the matter ourselves and although we felt very bad for a couple of days, we very slowly recovered although it was one month before all symptoms disappeared.
The last to go was the tingling and a queer reversal of sensations when a hot drink felt cold… and ice cream burnt my mouth. Known by the ancient Chinese, reported by Columbus on his first visit to the Caribbean, and accurately described by Pedro de Quiros during his Pacific voyage in 1606, ciguatera fish poisoning is endemic in all tropical areas and occurs regularly between latitudes 35°S and 35°N.
The situation is possibly even worse in the tropical Pacific Ocean, particularly in French Polynesia and the Marshall Islands. A creature of the ocean depths, normally only a few of these algae live on the reef but under certain circumstances their number can increase dramatically.
Fish feeding on coral ingest these toxic algae and so the toxin enters the food chain. A predatory snapper, grouper or barracuda then swims into the area and with one bite acquires all the toxicity its herbivorous victim had spent a lifetime collecting.
Much of the early research work had been conducted in French Polynesia, where ciguatera still causes hundreds of cases every year. In the late 1970s Dr Raymond Basis, head of the Medical Oceanographic Research Unit in Tahiti, finally identified the cause of ciguatera.
The toxic algae thrive on newly exposed coral surfaces multiplying very rapidly and so the cycle leading to ciguatera poisoning begins. Not everyone eating ciguatoxic fish has the same symptoms although diarrhea, nausea, abdominal pain or vomiting usually occur within a few hours.
Prickling in the fingers and toes as well as tingling around the mouth are other symptoms accompanied by an alteration of sensation causing cold objects or drinks to feel hot or plain water to taste like soda and a shower to feel like pin pricks of electric shocks. Other symptoms are extreme tiredness and lethargy, itching, muscle and joint pain, a weakened pulse and falling blood pressure.
The risks can be minimized by gutting fish as soon as it is caught and by not eating the head, liver, roe and viscera. The risks can be minimized by gutting fish as soon as it is caught and by not eating the head, liver, roe and viscera as the toxin is concentrated in these organs.
All very large fish caught inside a lagoon, or close to a reef, should be treated with suspicion, especially snappers, groupers, barracuda, jacks and moray eels. Dr Hakama of Hawaii University has perfected a test kit capable of identifying the presence of ciguatoxin in fish flesh.
When ingested, the toxin (ciguatoxin), which is present at high levels in these contaminated fish, may affect the digestive, muscular, and/or neurological systems. The initial symptoms may include itching, tingling, and numbness of the lips, tongue, hands, and/or feet.
Other symptoms during the first six to 17 hours are abdominal cramps, nausea, vomiting, diarrhea, and/or a red skin rash (pruritic). Chills, hot and cold temperature reversal, generalized weakness, restlessness, dizziness, wheezing, blurred vision, abnormal sensitivity to light (photophobia), muscle aches (myalgic), and/or joint pain (arthralgias) may also develop.
The acute symptoms of ciguatera fish poisoning generally disappear within a few days. Some affected individuals experience abnormally low blood pressure upon standing from a seated position (orthostatic hypotension).
In severe cases, there may be rapid progression to breathing difficulties (dyspnea) and muscular paralysis. Life-threatening complications (i.e., abnormally slow heartbeat, respiratory arrest, convulsions, or coma) may occur in these severe cases within 24 hours.
The source of the toxin responsible for ciguatera fish poisoning is found in high levels in a marine organism (dinoflagellate Gamabierdiscus toxic us) that typically inhabits low-lying tropical shore areas and coral reefs. This disease occurs with the greatest frequency in tropical and subtropical countries, particularly those in the Pacific and Caribbean areas.
However, a longer duration and more severe symptoms of ciguatera fish poisoning may be associated with increasing age. More severe symptoms may also be associated with the ingestion of a larger quantity of contaminated fish.
The presence of ciguatoxin has been reported in semen from affected males which can cause the symptoms of ciguatera fish poisoning in females after sexual intercourse. Since this toxin has also been identified in breast milk, it is also possible for affected mothers to pass this disease to their nursing children.
Standard Therapies The treatment for ciguatera fish poisoning is usually the immediate pumping out of all stomach contents (gastric lavage). Persistent nausea and vomiting must be treated with the intravenous administration of fluids to avoid dehydration.
If shock, convulsions or respiratory failure occurs, immediate appropriate medical measures must be instituted. Extra (a polysaccharide drug), Normal Human Serum Albumin, or blood transfusion may be necessary to treat shock.
Travelers to endemic areas should be cautioned about the risk of contracting ciguatera fish poisoning. Since travelers are at the same relative risk as people who normally live in endemic areas, they should be warned not to eat barracuda and should exercise caution when considering other fish such as grouper and red snapper.
