Understanding their feeding habits is essential to gaining insights into their behavior and potential risks they may pose to humans. Sharks have a diverse diet, reflecting their adaptability and position as top predators in their respective habitats.

There are three main categories of shark feeding habits: carnivorous, filter-feeding, and scavenging. Carnivorous sharks primarily prey on other fish, seals, sea lions, turtles, and even other sharks. Their strong jaws and teeth enable them to tear through flesh and bone, making them efficient hunters. Filter-feeding sharks, like the whale shark, consume large quantities of plankton by swimming with their mouth open, filtering the tiny organisms through specialized gill rakers. Scavenging sharks, such as the tiger shark, are opportunistic feeders that consume a wide range of prey, including carrion, garbage, and even human waste.

It is important to note that while sharks are renowned for their hunting abilities, unprovoked shark attacks on humans are exceedingly rare. Sharks are primarily interested in their natural prey and typically do not see humans as potential sources of food.
