Their ability to tolerate freshwater is rooted in salt retention. Sharks must retain salt inside their bodies. Without it, their cells will rupture and cause bloating and death. Given this requirement, most sharks cannot enter fresh water, because their internal salt levels would become diluted. What happens if you put a shark in freshwater? In […]

If you don’t take care of a shark once it’s aboard, the meat can stink. Properly handled, however, shark meat is white, firm, and surprisingly juicy. It tolerates a little overcooking the way codfish will not. Shark is firm, but not as dense as swordfish or sturgeon, and it is more tightly flaked than most […]

In many ways, shark meat is similar to other large ocean fish like swordfish or marlin. It’s a firm, white fish with meaty flesh. But it differs from other large seafood in one key respect, and that is the presence of a chemical called urea. Is shark a fish or meat? The top predators of […]

Think alligator and chicken. Depending on who is doing the dining, shark meat tastes like chicken — or roadkill. It’s meaty and mild — but has to be soaked well before it’s eaten because sharks urinate through their skin. Does shark meat taste like fish?

Shark meat is popular in Asia, where it is often consumed dried, smoked, or salted. What type of meat is shark? In many ways, […]

Sharks do eat bones. A shark’s powerful stomach acid can dissolve smaller bones like those in a fish. Others, like the bones of a mammal, may be regurgitated or digested, depending on the size. Can sharks bite through bone? The jaws of a great white shark can inflict a bone-crunching bite of up to 1.8 […]

1. Sharks do not have bones. Sharks use their gills to filter oxygen from the water. They are a special type of fish known as “elasmobranchs”, which translates into fish made of cartilaginous tissues—the clear gristly stuff that your ears and nose tip are made of. What makes sharks so interesting? Sharks are older than […]

Grey reef sharks hang out with the same “friends” in the same spot for years, a four-year study at the remote Palmyra Atoll in the Pacific Ocean has revealed. “We don’t think of sharks as social animals, but they do have social groups,” says Yannis Papastamatiou at Florida International University in Miami. Are sharks friends […]

Buoyancy: Cartilage is lightweight and thus much more buoyant than bones. Unlike bony fish, sharks do not need swim bladders to maintain neutral buoyancy. This is because their skeleton is made of cartilage. Since they don’t need to expel extra energy to stay afloat, there is more energy available for propulsion. What advantages do sharks […]

Cartilaginous skeleton Sharks, rays, skates, and chimaeras (also know as rat fishes) all have cartilaginous skeletons. Cartilage is less dense than bone, allowing sharks to move quickly through the water without using too much energy. Do sharks have cartilage instead of bones? So far, scientists have sequenced the genomes of eight bony fish and two […]

Zebra shark loves belly rubs, on The Feed! Do sharks like tummy rubs? As one Redditor noted, “no matter who or what you are, you can’t pass up a good belly rub.” This affectionate little interaction goes on for well over a minute before the shark drifts off and the diver picks up right where […]

Their research indicates, for example, that ceramic magnets are fairly reliable shark repellents, while super-strong rare earth magnets are not. Can magnets keep sharks away? Magnets repel sharks, studies show, by interfering with their ability to sense electrical fields. A recent study shows that magnets placed on the nets can repel sharks and rays from […]

“Sharks have an auditory system much like ours, with an inner ear canal that can interpret sounds,” Wynne said. Because sharks have been successfully hunted and attacked by killer whales, Wynne’s idea is to use the sounds of killer whales mixed with high frequencies (below 500 hertz) to scare sharks away. What sound do sharks […]

Sharks live in most ocean habitats They can be found in beautiful, tropical coral reefs, to the deep sea, and even under the Arctic sea ice. Where do most sharks commonly live? ocean habitatThey are found in just about every kind of ocean habitat, including the deep sea, open ocean, coral reefs, and under the […]

No. Sharks are attracted to blood, but they won’t attack you because you are on your period. A shark can detect any bodily fluid in the water. Do sharks react to human blood? Sharks are attracted to human blood They can also detect blood in the water from miles away. Contrary to popular belief, however, […]

Do Sharks go Crazy When They Smell Blood? No. This is just another example of misconceptions built by the dramatic movies about sharks losing their minds and attacking humans just because they smell a drop of blood. This fact is backed up by an experiment by Skylar Thomas from the White Shark Studio Company. Do […]

It has traditionally been believed that sharks are repelled by the smell of a dead shark; however, modern research has had mixed results. The Pardachirus marmoratus fish (finless sole, Red Sea Moses sole) repels sharks through its secretions. What scents do sharks hate? Shark Repellent In the ensuing years, researchers found that sharks were repelled […]

The largest thresher shark ever recorded was 24.9 feet (7.6 m) long, and the heaviest weighed more than 750 pounds (340 kg), according to the Florida Museum of Natural History (opens in new tab). What is the largest white shark ever caught? The biggest great white shark ever recorded is a female shark affectionately named […]

Fish fingers (British English) or fish sticks (American English) are a processed food made using a whitefish, such as cod, hake, haddock, shark or pollock, which has been battered or breaded. They are commonly available in the frozen food section of supermarkets. Are fish fingers 100% fish? Cod Fillet Fish Fingers, Lightly Fried. 100% Cod […]

MYTH: If a shark’s fin is cut off, it will just grow back. Sharks cannot actually grow back fins that are cut off. (But some other fish can.) This biological fact is even more troublesome in light of the growing shark fin trade — especially in Asia, where the fins are a key ingredient in […]
