Black whales are almost at the top of the marine food chain. Black whales are top hunters who hunt sharks, especially great whites. Great white sharks like to eat seals. In the sea area with seals, there are usually many great white sharks. If killer whales appear nearby, great white sharks will flee quickly. According to oceanographers' research, a pair of killer whales settled near Voss Bay in South Africa, and the number of great white sharks nearby dropped sharply.

Sharks have the strongest bite force in the animal kingdom, and killer whales can bite off the liver of great white sharks with one bite. Black whales especially like the liver of great white sharks, which weighs 280 kilograms and is rich in fat and protein. Black whales know exactly where the liver is in sharks and often take it out with almost surgical accuracy.

Shark characteristics

Sharks are hard, muscular and spindle-shaped to varying degrees. The nose and mouth are pointed according to different species, such as mako shark and great white shark; There are also big and round ones, such as tiger sharks and wide-headed tiger sharks. The vertical tail (caudal fin) is generally crescent-shaped, and the upper part of most species caudal fin is much larger than the lower part. It is particularly sensitive to the smell of seawater, especially to the smell of blood.

Most sharks feed on marine animals such as fish. They sleep during the day and come out at night. Shark is a predator who is good at camouflage, because its upper body is dark and its lower body is bright, so it can sneak up on its prey with this protective color.
