Despite their scary reputation, sharks rarely ever attack humans and would much rather feed on fish and marine mammals. Only about a dozen of the more than species of sharks have been involved in attacks on humans. Sharks evolved millions of years before humans existed and therefore humans are not part of their normal diets. Sharks are opportunistic feeders, but most sharks primarily feed on smaller fish and invertebrates. Some of the larger shark species prey on seals, sea lions, and other marine mammals. Sharks have been known to attack humans when they are confused or curious. If a shark sees a human splashing in the water, it may try to investigate, leading to an accidental attack. Still, sharks have more to fear from humans than we do of them. Humans hunt sharks for their meat, internal organs, skin, and fins in order to make products such as shark fin soup, lubricants, and leather. Sharks are a valuable part of marine ecosystems, but overfishing threatens some shark populations. NOAA Fisheries conducts research on shark habitats, migratory patterns, and population change in order to understand how to best protect and maintain a stable shark population.

Unlike bony fish, sharks have no bones — their skeleton is made of cartilage, which is a tough, fibrous substance, not nearly as hard as bone. What Do Sharks Eat? Maybe you like fish, too, or pizza. The young are nourished by the yolk of their egg and by fluids secreted by glands in the walls of the oviduct. Sharks even eat other sharks. Only about a dozen of the more than species of sharks have been involved in attacks on humans. Normally, sharks eat alone. Hunting habits of sharks help to the survival of the fittest or the most adapted to the environment because sharks often make older, weaker or sick individuals their favorite target.
Asking what do sharks eat is a little like asking what do dogs eat. It depends on the species. A Great Dane won’t have the same exact diet as a Chihuahua. The size and breed can affect dietary preferences. A Great White Shark won’t eat the same things as a Dwarf Lanternfish, which is a truly massive seven inches in length. Generally speaking, a shark will eat most any fish smaller than itself. They tend to eat whenever food is available regardless of being hungry and go into a feeding frenzy at the scent of blood in the water. Sharks have the ability to sense electromagnetic fields produced by their prey.
