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.
The moment a Goliath grouper eating a shark was captured on camera as shocked fishermen look on. The skeletal structure of large Goliath groupers cannot adequately support their weight out of the water without some type of damage,” the Florida Fish and Wildlife Conservation Commission (FCC) stated on its website.
“If a large Goliath is brought onboard a vessel or out of the water, it is likely to sustain some form of internal injury and therefore be considered harvested.” In another incident years ago, a grouper was spotted eating a blacktop shark.
(Break.com)The predator was identified as an Atlantic Goliath grouper, which can weigh as much as 790 pounds and can grow up to 8.2 feet in length. The fishermen hooked the shark off the coast of Bonita Springs, Florida, several years ago before the grouper took over.
As Business Insider noted, Goliath groupers are known to stalk and ambush divers. “They were once so overfished in the southeastern United States, they were considered for listing under the Endangered Species Act,” according to NOAA.
They’re found in shallow tropical waters near coral reefs, and its range extends from the Florida Keys to the Gulf of Mexico. In the eastern Atlantic Ocean, Goliath grouper are found off the coast of Africa from the Congo to Senegal,” says NOAA.
“Threats to the species include commercial and recreational fishing, harmful algal blooms (red tide), and habitat loss,” says the NOAA website. Black owns Crazy Lure Bait & Tackle Shop in Cape Coral, Florida.
A group of fishermen is able to witness a 500-pound grouper ’s “rare” meal during a fishing trip off the coast of Everglades City, Fla., last week. Captain Jimmy Wheeler with Everglades Fishing Company watched as someone in his group caught a 3-foot shark.
They must be immediately returned to the ocean (unharmed) if they are accidentally caught on a fishing line.

Though the amount of mercury in fish greatly varies depending on the type of fish, their size, weight, and age, it is still noteworthy to learn how these pollutants may pose potential health risks among us as consumers if we eat too much of it. So as my wife and I were doing some research in hopes of promoting a solid diet and healthier lifestyle (and because she is pregnant right now), here is the list of those saltwater fish species that could do more harm than good to you and your health if eaten out of moderation.
Strong Angler Cameron Parsons with a nice king fish FDA warns children, pregnant women and lactating moms to NOT eat any king mackerel due to their very high mercury content. Eliminating these fish species in your diet can definitely reduce your chances of getting exposed to the harmful effects of mercury and other existing contaminants.
Health advocates encourage children as well as pregnant and nursing mothers to only consume three to six-ounce portions of white tuna in a month. According to a CNN report, this type of fish has extremely high levels of metal mercury that can eventually cause coordination loss, blindness and even death, depending on the amount or portion ingested.
Scientists believed that such increased mercury content was due to the accumulation of certain contaminants in their body as they eat lots of smaller fish. “What we found for our 124 sharks that we sampled was that about one-third of them came in with mercury levels that were over the Food and Drug Administration’s action level of one part per million,” Robert Hunter, director of Mote Marine Laboratory’s Center for Shark Research in Sarasota, said in a statement.
The cobra is a delicious saltwater fish that sadly can soak up a lot of mercury. Strong Angler Tina Corrode with what’s left of her swordfish you like catching daytime or nighttime swordfish, you might want to be careful how much of it you eat.
Although most people throw back jacks and refer to them as a “junk fish”, but for those of you that do eat them, be careful! Greater Amber jack South Atlantic grouper (i.e. gag, scamp, red and snowy) Tile fish (also called golden or white snapper) Banded Rudder fish.
One thing that most of the articles failed to mention was the role that selenium plays in fish. Needless to say, it’s basically what you know (i.e. lowering your mercury risk exposure) that can really help you keep a healthy mind and body.
It’s a bit extreme, but that type of trip still doesn’t seem as crazy as fishing the middle of Tampa Bay for gag grouper and sharks in a kayak. Erik Stevens, who guides anglers from a Hobin PA17T 17-foot catamaran style kayak.
The system is mimicked to how a penguin moves through the water, and two people doing it together is easy, smooth, steady and comfortable.” Stevens’ gag grouper trips range from eight get of water on flats edges all the way to the middle of the bay.
If the wind is going predominately one direction, he’ll arrange a start and pickup going all the way across the bay. During the trip he’s fishing channel edges and hard bottom with heavy tackle.
Heavy spinning gear is Stevens’ preferred grouper tackle, with 40-60 pound rated rods and 8500 or bigger series reels that he trolls big lipped diving plugs on with heavy braided line. These fish are big and mean and pull hard so you better hold on tight.
This past week Stevens was able to put fellow kayak enthusiast Pamela With on four gag grouper, including one keeper sized fish, in just 45 minutes of fishing. The biggest fish we hooked was eaten to his head by a shark.
