Nearly every part of a shark is edible, from the thick muscle fillets to the fins, skin, cartilage, and even the liver. That said, not every part is equally appealing or easy to prepare. Shark meat requires specific handling because of its unique body chemistry, and some parts carry real health concerns worth knowing about before you buy or catch one.
Muscle Meat: The Main Cut
The loin fillets and steaks cut from a shark’s body are the part most people eat. Shark meat is dense and firm, closer in texture to swordfish or even beef than to typical flaky fish. A 100-gram raw serving of blacktip shark delivers about 21 grams of protein and 5 grams of fat at just 130 calories, with zero carbohydrates. It’s also a strong source of selenium, packing 36.5 micrograms per serving.
In U.S. markets, the three species you’ll most commonly find are mako, thresher, and blacktip. Mako is the most sought-after for its mild, slightly sweet flavor and steak-like firmness, making it a natural fit for grilling. Thresher and blacktip are also solid choices with a clean taste. All three hold up well to high heat, marinades, and bold seasonings, which is why grilled shark steaks are such a popular preparation.
Why Shark Meat Needs Special Preparation
Sharks don’t urinate the way other fish do. Instead, they retain urea in their blood and tissues to maintain the right salt balance in their bodies. When a shark dies, that urea breaks down into ammonia, which is why improperly handled shark meat can smell and taste harsh. This is the single biggest barrier to enjoying shark, and it’s entirely solvable.
Soaking the meat in a weak acid solution like citrus juice or vinegar can remove up to 90% of the urea. Many cooks also soak fillets in milk or saltwater brine for a few hours before cooking. The key is to start this process as soon after the catch as possible. If the meat already has a strong ammonia odor, it’s likely too far gone. Fresh, properly handled shark meat should smell clean and mild, like any other ocean fish.
Shark Fins
Shark fins have been used in Chinese cuisine for over a thousand years, dating back to the Song Dynasty around 900 AD. Shark fin soup became a symbol of wealth and celebration, traditionally served at weddings and banquets. The fins themselves contribute almost no flavor. Their role is textural: once prepared, the cartilage fibers soften into thin, gelatinous noodle-like strands that give the soup its signature body. The actual taste comes from the broth, typically a rich chicken or pork stock.
Preparing fins from scratch is labor-intensive. Dried fins must be soaked and cleaned over several days before they’re ready to cook. More importantly, shark finning (the practice of slicing off fins and discarding the rest of the shark at sea) is banned in the United States and many other countries. Several shark species now require CITES trade documentation for their fins to be legally imported. If you’re buying fins, sourcing matters both legally and ethically. Some cooks use fins from sharks they’ve caught whole and processed themselves, like blacktip sharks, as a way to use the entire animal.
Skin and Cartilage
Shark skin is edible once the tough, sandpaper-like outer layer of tiny tooth-shaped scales (called denticles) is removed. In some cuisines, particularly in Japan and parts of Southeast Asia, the skin is dried, rehydrated, and added to dishes for its chewy, gelatinous texture. It can also be fried into crispy chips. The cartilage that makes up a shark’s skeleton (sharks have no true bones) is sometimes dried and ground into powder, sold as a dietary supplement, though the health claims around shark cartilage supplements remain poorly supported.
Liver
A shark’s liver is enormous, sometimes making up a quarter of its total body weight. It’s rich in an oil called squalene, which is widely sold as a health supplement in capsule form and used in cosmetics. Shark liver oil also contains high concentrations of vitamin A. In some coastal communities, the liver is eaten directly or rendered into oil for cooking.
There’s a caveat, though. Research on hamsters found that both squalene and shark liver oil raised cholesterol levels when consumed regularly, suggesting some caution is warranted if you’re taking these supplements long-term. The liver also tends to accumulate environmental contaminants at higher concentrations than muscle meat, so it’s not something to eat in large quantities.
Hákarl: The Fermented Exception
One of the most unusual ways to eat shark comes from Iceland, where Greenland shark is fermented into a dish called hákarl. Greenland shark flesh is toxic when fresh because of extremely high levels of trimethylamine oxide (TMAO) and urea. The traditional fermentation process neutralizes these compounds. Fresh shark meat is buried or placed in containers and fermented for seven to eight weeks, during which TMAO levels drop below detectable limits within about five weeks and the pH rises from around 6 to 9. The meat is then hung to dry for another five weeks.
The result is intensely pungent, with a strong ammonia smell that catches most first-timers off guard. Hákarl is typically eaten in small cubes and is considered an acquired taste even among Icelanders. It’s a striking example of how fermentation can transform an otherwise inedible species into food.
Mercury Is the Biggest Health Concern
Sharks sit at the top of the ocean food chain, which means mercury accumulates in their tissues over a lifetime of eating smaller fish. FDA testing of 356 shark samples found an average mercury concentration of 0.979 parts per million, with some individual samples reaching as high as 4.54 ppm. That average is among the highest of any commercial seafood. For comparison, most fish that are considered low-mercury options come in under 0.1 ppm.
This doesn’t mean you can never eat shark, but it does mean frequency matters. Pregnant women, nursing mothers, and young children are generally advised to avoid shark entirely. For other adults, treating shark as an occasional meal rather than a weekly staple keeps exposure in a reasonable range. The mercury content is consistent across all edible parts, though organs like the liver may concentrate additional toxins.
Legal Restrictions to Know
Not all sharks are legal to harvest or sell. In the U.S., oceanic whitetip sharks and a Caribbean population of scalloped hammerheads are listed as threatened, and fishermen can only keep them in limited circumstances. Several other species require specific trade permits under CITES, the international agreement that regulates wildlife trade. Shark finning is federally banned in U.S. waters, meaning any legally landed shark must come to shore with its fins still attached. Individual states have additional rules: some ban the sale or possession of shark fins altogether, regardless of how the shark was caught.
If you’re buying shark at a fish market or restaurant, commercially sold species like mako, thresher, and blacktip are the ones most commonly available through legal, managed fisheries. Knowing what species you’re eating is worth the effort, both for safety and for staying on the right side of the law.
