Docile and slow-moving, zebra sharks are not dangerous to humans and can be easily approached underwater. However, they have bitten divers who pull on their tails or attempt to ride them. Are zebra sharks aggressive? Adult zebra sharks are non-aggressive, and have few predators other than larger shark species that may be lucky enough to […]

Far from being solitary animals, as they have been historically seen, sharks can actually form complex social network that are typically seen in mammals but rarely observed in fish, new research has found. Are sharks lonely? SHARKS ARE LONERS Sharks don’t have to rely on each other to survive. However, some species of sharks cooperate […]

Nurse sharks tend to swim near the bottom of their chosen areas, are slow-moving and are relatively harmless to humans. Unlike their more carnivorous and curious cousins, they prefer to stay on their regular diet. They have very strong jaws to crush and eat shellfish but their preference is fish, shrimp, and squid. Is the […]

Sharks do not circle in the water before they attack, it is simply their way of trying to form an image of what they are confronting in the water. According to my own numerous observations this motion is a sign of pure curiosity and not an incentive to circle its prey and feed. What to […]

Use single barbless circle hooks. If your hooks are not barbless, flatten the barb with a pair of pliers. Use a hook remover for throat hooked sharks. If the shark has swallowed the hook, do not attempt to pull it out – this will cause serious damage and compromise the survival of the shark. How […]

Jensen admitted the diver did receive criticism from the shark diving community–not for removing the hook, but for the color of his gloves. A diver successfully removes a hook from a lemon shark’s mouth, though shark scientists say the hook may naturally rust and fall out. What happens to hooks left in sharks? Many sharks […]

Although the shark will undoubtedly swim away as fast as possible when you release it, catch and release is harmful to sharks. Biologists have evidence of this. They have documented cases where sharks will swim away and die within a matter of minutes after fishermen release them. Do sharks live after catch and release? After […]

Leave fish in the water if possible. If that isn’t possible, minimize the time the fish is out of the water (just long enough to take photos and measure the fish). If possible, keep the fish from thrashing without using a net. If a net is required, use a rubber-mesh landing net instead of abrasive […]

In a study to determine the physiological effects of stress due to line fishing, scientists found that most sharks showed high levels of lactic acid in their blood, and that hammerhead sharks were most sensitive and had a higher mortality rate after release. Do sharks ever get scared? They’re apex predators that have existed for […]

It is prejudice. Sharks do not circle in the water before they attack, it is simply their way of trying to form an image of what they are confronting in the water. According to my own numerous observations this motion is a sign of pure curiosity and not an incentive to circle its prey and […]

According to new research from the Hawai’i Institute of Marine Biology at the University of Hawai’i Mānoa, fishhooks embedded in a shark’s skin or mouth can remain for several years and lead to major health problems, including internal bleeding and necrosis. What happens if a shark swallows a hook? If the shark has swallowed the […]

They do eat other species of sharks, however, and they are known for embryonic cannibalism, a kind of gestational gladiatorial combat where the toughest hatchling devours its siblings while still in the womb. Can a shark eat a shark? “A lot of species of sharks eat other species of sharks and within a species you […]

“The fact of the matter is there’s a decent chance you can get bitten, and the reality is sharks are pretty tough critters, so a hook in the mouth isn’t a problem for them. It will eventually rust out on its own, so poses no danger to the shark.” Can a shark survive with a […]

Shark muscle, blood and digestive tracks have been sampled, and they were found to contain pathogens including several kinds of Vibrio, E. coli, C. botulinum, and a dozen other disease-causing microorganisms I had never heard of but seem to result in extremely unpleasant symptoms. Why do sharks not get ill? It has puzzled researchers for […]
