But you may be surprised to learn that large grouper will also eat sharks ! It’s known that killer whales will attack and kill great white sharks.
Apart from these large whales, there aren’t many other sea creatures that are big enough to eat sharks. But it turns out that grouper have an appetite for younger sharks too.
During a deep sea dive off the South Carolina coast, NOAA scientists filmed a shark swallowed whole. Watch how these young sharks feed on a saw-fish that’s died and sunk to the bottom.
There’s a bit of a feeding frenzy going on by these small sharks. But it’s not just these sharks that draw the attention of the NOAA scientists.
Photograph by Raul Toulon, National Geographic Creative The Atlantic Goliath grouper (Epimetheus Tamara) isn’t the meanest or fastest fish on the reef. Though the Atlantic Goliath grouper can grow up to 800 pounds (363 kilograms) and eight feet (2.4 meters) in length, it subsists almost entirely on smallish mud crabs.
“From all available data, Goliath grouper do not eat sharks,” said Dr. Matthew Craig, a National Geographic grantee and marine biologist at the University of San Diego in California. Christopher Koenig, a biologist from Florida State University, confirms that groupers preying on sharks is unlikely under normal conditions.
While some fishermen say Goliath groupers have bounced back since then and should be taken off the Endangered Species List, most conservationists agree that the slow-growing giants are still recovering. Watch video of Goliath groupers up close with photographer David Doublet, who shot the images for a story on this fish in the July issue of National Geographic magazine.
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.
Although both venomous and poisonous animals produce a toxin that can be harmful to other organisms, the method of delivery is different. Lionfish possess venomous dorsal, pelvic, and anal spines that deliver toxin through an unpleasant puncture wound.
Myth #2: Lionfish were released in the Atlantic when an aquarium flooded during Hurricane Andrew in 1992. Truth : Lionfish were first spotted near Dania, Florida in 1985, years before Hurricane Andrew.
The initial source of the invasion can be pinpointed to personal aquarium releases, probably by people whose lionfish were getting too big for the tank or eating the other fish. This raises concerns due to the inherent risks involved with teaching wild animals to see humans and expect a free meal.
There have even been reports of sharks, eels, and barracuda becoming aggressive towards lionfish hunters in anticipation of handouts. Additionally, a recently released study that examined lionfish/predator abundance throughout the Caribbean over the course of three years determined that there was no correlation between native predator densities and lionfish densities, suggesting that native predators do not influence the successful invasion of lionfish.
The intricate coloring and patterns of the lionfish make them a very popular aquarium fish. In fact, there are many restaurants throughout the Caribbean and southern United States that are featuring lionfish on their menus to promote awareness while satisfying customers.
Although many researchers agree that complete eradication of lionfish is impossible, there are certainly ways to keep the population in check and protect the native marine ecosystems of the Western Atlantic, Gulf of Mexico, and Caribbean. Instead of trying to determine a single winner, this list features 10 amazing creatures that all possess their own impressive kind of strength, relative to their size.
You might be surprised by some animals that made this list, but you surely wouldn’t want to get on the bad side of them, no matter how small they are! However, the reality is that the majestic and typically docile elephant wins the prize for the world’s strongest mammal.
An Asian elephant has more than 150,000 muscle units in its trunk alone, and this level of power allows it to easily uproot fully grown trees or forcefully spray up to a gallon of water. Some eagle species are known to prey on comparatively large animals like monkeys and sloths, so it should come as no surprise that they are able to easily lift things that are many times their own weight during flight.
As soon as you take one good look at the Atlantic Goliath grouper, you will likely understand how it got the title of “strongest fish.” They can grow to be up to nine feet long. Fishermen who want a serious challenge often seek out Goliath groupers because their enormous size and relative strength makes them extremely difficult to land.
When you search the internet for terms like “world’s strongest animal,” the dung beetle is almost always one of the top results. The dung beetle certainly earns its place as one of the strongest animals in the world, especially when you consider its size versus how much it can carry.
They typically grow to be up to one inch long and weigh less than an ounce, but they can carry an amazing 1,141 times their own body weight. To put that kind of strength into perspective, if a human could move that much weight, it would be the same as one person pulling six full double-decker buses by themselves.
While they cannot carry quite as much as a dung beetle relative to their size, these insects are still believed to be able to move a whopping 850 times their own body weight. A big enough anaconda has been known to kill large deer, jaguars, and even black caimans (a reptile similar to an alligator).
Anacondas can constrict around their prey with the strength of at least 10 powerful men, so they are generally considered to be apex predators. In addition, they can travel easily at speeds up to 23 miles per hour for long distances, and they can move at least 30 tons through the water.
When threatened, an adult zebra can kill a fully grown male African lion with a single blow to the body. They have immensely strong front legs and are built to take down large creatures like elk, musk ox, bison, and reindeer.
There have been occasional unconfirmed reports of giant groupers big enough to swallow a man :: for example Arthur C. Clarke wrote that he saw one in a sunken “floating dock” off Sri Lanka. An item in a USA scuba divers' magazine I once read, said that in an incident at sea a big grouper sucked a scuba diver into its mouth head first so far that even his fins went inside; luckily its prey-crushing heavy pharyngeal teeth closed only on his scuba cylinder and dented it right in, and it spat him out alive and uninjured.

On rare occasions I have been subjected to territorial displays, bumping and once, in the case of a very large bull shark, aggressive staring.
My point is that aside from deeply triggered instinctive behavior, apex marine predators usually treat me the way I would treat a visitor from one of Neptune’s moons who had a weird body shape almost as big as mine. I think sharks have a greater range than groupers and other inshore reef fish.
Raw Member One thing to remember about groupers is that they are also prized food fish. Taking that into account, most of the larger groupers pieces numbers are “kept in check” more by human intervention that anything else.
A recent case in point would be the proposal in Florida to reopen Goliath Groupers to sport fishermen, based on the argument that their increased numbers (barely back from nearly complete annihilation) are causing a lack of smaller fish for the sport fishermen to catch... * Unfortunately, it seems, that we humans are reluctant to acknowledge that we don’t fully appreciate how marine ecosystems work and how our actions impact them... Underwater Journal Here in Florida, particularly in Palm Beach County, we have a sizeable population of Goliath groupers (Epimetheus Tamara), which grow to the same size as the Queensland Cod (Epimetheus lanceolatus) in the Indo-Pacific and Western Pacific.
As a South Florida resident, I spend a lot of time diving (on CCR of course) with these magnificent reef fish, and have as many as 60 plus around during their spawning season, which runs August through September. I have seen a shark fight a Queensland grouper over a hooked fish and lose...
There have been occasional unconfirmed reports of giant groupers big enough to swallow a man :: for example Arthur C. Clarke wrote that he saw one in a sunken “floating dock” off Sri Lanka. On a TV sea biology program I once saw sharks attacking and demolishing a large grouper that they had caught in the open.
I still suspect that when the sharks are gone, there will be much less control (except cold water) on where Epimetheus lanceolatus operate and how big they grow. On a TV sea biology program I once saw sharks attacking and demolishing a large grouper that they had caught in the open.
I still suspect that when the sharks are gone, there will be much less control (except cold water) on where Epimetheus lanceolatus operate and how big they grow. Your post describes several factors which illustrate my points about range and habitat: a giant grouper who has grown too big to leave a confined space, has a very big advantage in terms of the energy it must expend to eat any prey unlucky enough to enter the cage, basically none.
On the reef or a shipwreck, the grouper has the advantage of cover and a more local knowledge of its surroundings. If shark numbers dwindle in a particular area, it’s hard to imagine giant groupers significantly expanding their ranges without running into other giant groupers who will challenge them at risk of injury for both.
I can ’t imagine any animal looking at a flailing, 4 climbed creatures like an adult human and think it’s going to be easy to swallow them whole without a fight.
