Great whites use their speed and coloring to help them hunt. They search for prey at the surface of the ocean while swimming below. Once they spot a target, they use a burst of speed to bump their prey while simultaneously biting it. They have several rows of teeth that can number into the thousands. As teeth fall out, they are rapidly replaced by those in the row behind them. These sharp, serrated teeth can be devastating. A single, large bite can be fatal.
The great white is at the top of the food chain and has few threats in the ocean. Only orcas and larger sharks can pose a risk. The only other risk to the great white shark is human interaction. They are sometimes caught by accident in fishing nets or intentionally sought out by sport fisherman. Their jaws and fins are sold for considerable amounts of money
Great whites, like many other sharks, have rows of teeth behind the main ones, allowing any that break off to be rapidly replaced. Their teeth are unattached to the jaw and are retractable, like a cat’s claws, moving into place when the jaw is opened. Their teeth also rotate on their own axis (outward when the jaw is opened, inward when closed). The teeth are linked to pressure and tension-sensing nerve cells. This arrangement seems to give their teeth high tactile sensitivity. A great white’s teeth are serrated and when the shark bites it will shake its head side to side and the teeth will act as a saw and tear off large chunks of flesh. Great whites often swallow their own broken off teeth along with chunks of their prey’s flesh. These teeth frequently cause damage to the great white’s digestive tract. However great whites often feed on stingrays and swallow the ‘sting’ as well, the barbed sting often getting stuck in the shark’s guts. There are anecdotal reports of the sting working its way out through the shark’s side. Correspondingly, a tooth causes the shark no major harm.
Hunting And Diet Of A Great White Shark
Highly adapted predators, their mouths are lined with up to 300 serrated, triangular teeth arranged in several rows, and they have an exceptional sense of smell to detect prey. They even have organs that can sense the tiny electromagnetic fields generated by animals. Their prey includes other sharks, crustaceans, molluscs, and sea birds. Larger whtie sharks will also prey on sea lions, seals, and small toothed whales like orcas. The species has even been seen feeding on dead whales.
Of the 100-plus annual shark attacks worldwide, a third to a half are attributed to great white sharks. Most of these, however, are not fatal. Research finds that great whites, which are naturally curious, often “sample bite” then release their human target. It’s not a terribly comforting distinction, but it does indicate that humans are not actually on the great white’s menu. Fatal attacks, experts say, are typically cases of mistaken identity: Swimmers and surfers can look a lot like their favorite prey—seals—when seen from below.
Newborn white sharks feed on fishes and other sharks. As they reach adulthood, their prey includes sea turtles, seals, sea lions, porpoises, dolphins, and small whales. Prey is usually hunted by ambush, where the shark will attempt to rush the animal by surprise and inflict a sudden and massive fatal bite. Often this initial rush is so strong that the intense impact may send the prey out of the water or will send the shark into the air if it misses the target. The sharks will retire and wait for the prey to quickly die, giving rise to the terms bite and spit or bite and wait for this method of attack. White sharks are also opportunistic scavengers and will feed on the carcasses of whales and basking sharks; however, they are not indiscriminate.

Population And Conservation
There is no reliable population data for the great white shark, but scientists agree that their number are decreasing precipitously. Overfishing and getting accidentally caught in fishing nets are their two biggest threats. The species is classified as vulnerable—one step away from endangered—by the International Union for the Conservation of Nature.
