They have the largest olfactory bulb as compared to other sharks, capable of detecting substances as small as 1 part per 10 billion parts of water. Great white sharks have an acute sense of smell. These pulses also resemble the vibrations emitted by injured or sick prey. Sounds travel 4 ½ times faster in water than on land, and sharks are drawn to low-frequency pulses, in the range of 25 Hertz (Hz) to 100 Hz as far as 820 feet away. They also have an ear stone (otolith), which provides gravitational input to the position of their own body in the water, making them powerful navigators. Sharks have sensitive ears capable of detecting vibrations in the water. These are connected to hair-like structures that project out allowing them to feel vibrations in the water, helping them to locate prey. Like other fish, sharks have lateral line organs, called neuromasts. The size of great white sharks can be up to 21 feet in length, weighing up to 5,000 pounds, making them large and strong contenders. Their scale-covered, torpedo-shaped, muscular bodies powerfully navigate marine waters at speeds up to 35 miles per hour (mph). Great white sharks are efficient and powerful hunters and tend to be more active during dawn and dusk. The design of the shark allows it to efficiently seek out prey in marine waters. Shark Anatomy: In Seeking And Capturing Prey Humans may also look like natural prey, such as sea lions or seals.Īttacks on humans may also result from poor or lacking sources of food in the water. Sharks may be investigating a source through biting to see if it is desirable prey. They spend the majority of their time in the water searching for food. Great white sharks are apex predators, feeding on prey such as rays, fish, seals, sea lions, dolphins, penguins, small whales, and whale carcasses. Their powerful bodies and acute senses in the water make them experts in obtaining food. Characteristics That Make Great White Sharks DangerousĪs apex predators, the need to feed is the shark’s primary driving force in attacks. The majority of these attacks happen in nearshore, shallow waters where people are also spending recreational time. Wasp Nest: 7 Differences (ID Guide With Pictures)įatality rates from shark bites are about 7% in the United States, more than 20% in South Africa, and up to 60% in Australia. In cases where this species can be clearly identified, there have been over 55 counts of fatal and over 295 non-fatal incidents found globally. The great white shark is on record as having the highest number of unprovoked attacks on people. These are also coasts where people may be fishing, swimming, surfing, boating, and so on in these waters along with the shark’s prey. Sharks feed on the abundance of prey that live there. Great white sharks ( Carcharodon carcharias ) are large fish found in temperate, coastal waters such as near the United States, Japan, Australia, and Africa.
