I. What kind of food do killer whales eat
1. The food of killer whales includes fish, other cetaceans, fin-footed, sea otters, birds, reptiles and cephalopods. Of the 362 stomachs of the killer whales collected in the Antarctic, 217 contained fish, 75 contained minke whale residues, 35 contained fin-footed and 35 contained cephalopods.
2. Killer whales have very well-developed brains and strong bodies, and with these advantages, these highly intelligent animals can chase down and kill many of the ocean's top predators, and some members of the killer whale family have menus that list at least nine shark delicacies, including the great white and mackerel sharks, which are feared by many animals.
2. What food does a great white shark eat
1. The great white shark's favorite predator is fish, turtles, seabirds, sea lions, as well as walruses and seals of a similar weight to its own, and even giant baleen whales on the verge of death, and occasionally eats dolphins, whale carcasses, and other sharks, in addition to devouring many other things such as sea otters, and dead fish floating on the surface of the sea.
2, the great white shark has extremely sensitive sense of smell and touch, can smell 1 kilometer away from being diluted into the original 1/500 concentration of blood odor, to 69 kilometers per hour speed to rush to, but also can detect biological muscle contraction of the tiny electric current, so as to judge the prey size and movement. Great white sharks, meanwhile, are so adept at hunting that they often resort to surprise attacks in order to effectively capture their prey.
Three, killer whales vs great white sharks who is powerful
1, body type comparison: killer whales are 8 to 10 meters long, weighing 9 tons or so, the upper and lower jaws of each tooth column has 10 to 12 conical teeth, long, thin mouth, sharp teeth, ferocious character, predator, good at prey. Great white shark is the largest predatory fish, body length up to 6.5 meters, weighing 3200 kilograms, the tail is crescent-shaped, teeth large and serrated edge, triangular, teeth 10cm long, belonging to the large aggressive shark.
2, predatory skills: killer whales will use their tails to drive sharks out of the water, in the whole process does not need to contact the body with sharks, but the use of the tail generated by the upward force to create a vortex, the sharks will be placed on the water current formed when it moves. Once the prey is out of the water, it turns its body while extending its tail out of the water. Great white sharks specialize in hunting and generally use surprise attacks in order to effectively capture their prey. First in the water under the ambush, after confirming the prey will be from the bottom to the top of the attack on the prey, general attack, the first hit will make the prey seriously injured, the great white sharks will then stop the attack, until the prey died of blood loss, and then enjoy the food.
3, teamwork: killer whales sometimes hunt in groups, using ultrasonic communication and contact from the rumble (the dolphin family to make echo-location parts, will focus the sound), and develop tactics, the combined efforts of the school of fish into a large ball, and then take turns to eat. Great white sharks are also not lone hunters but social pack animals, when gathered together, some look assertive and some look timid, and will cooperate with each other when feeding, for example, one will take the initiative to attract the seal's attention while the other attacks the seal from behind.
4, it can be seen that the killer whale vs great white shark who is powerful is obvious, once recorded, there are killer whales in the sea generally do not have great white sharks, and some people in the body of a great white shark equipped with a locator, and then found a killer whale in the vicinity of the great white sharks immediately dived into several hundred meters deep water, antelope on the cheetah's fear of the degree of the cheetah will not be so deep, and there are killer whales predation of great white sharks in the documentary, and the killer whale predation of great white sharks. Killer whales can kill great white sharks, great white sharks can't kill killer whales, killer whales don't often attack great white sharks also just because they are not interested in the meat of great white sharks.
