Hunting methods and eating habits
1, feeding habits: killer whales passing by prefer to eat seals, walruses and so on. Marine killer whales prefer sharks and resident killer whales prefer salmon.
2. Hunting: Sometimes killer whales hunt in groups, and use the ultrasonic waves emitted by the ridge (the part used by the dolphin family for echolocation, which will concentrate the sounds into a beam) to communicate with each other and plan tactics. Qi Xin will work together to concentrate the fish into a big ball, and then take turns to drill in and feed them.
3. Food: The killer whale's food includes fish, other whales, pteropods, sea otters, birds, reptiles and cephalopods. Of the 362 killer whale stomachs collected in Antarctica, 2 17 contained fish, 75 contained the remains of minke whales, 35 contained pteropods and 35 contained cephalopods.
habitat
Killer whales live mainly in polar and temperate waters. Japan's Beihai and Iceland, which are widely distributed all over the world, seem to have no obvious restrictions on factors such as water temperature and water depth.
