brief introduction
Black whale is a kind of mammal, belonging to the genus Black whale of Dolphinidae. Adults weigh 6600 kilograms, with an average body length of 6-9 meters; The head is slightly round, and the beak is not obvious or has no beak; The body is black and white; There are oval white eye spots at the back and upper parts of the eyes; The maxilla and mandible each have 10- 12 conical teeth; Males are longer than females and weigh twice as much as females.
The black whale has a big head, black and white, and is regarded as a tiger, hence its name. Black whales are distributed in the waters near Liaoning, Shandong, Zhejiang and Taiwan Province provinces in China, as well as in the oceans all over the world, and are common in high latitudes and coastal waters. Black whale is a marine species with no fixed habitat. They mainly chase their favorite fish or other marine animals, usually 5-20 fish gather in groups.
There are also groups that reach 100 or above. In addition to eating big fish, killer whales often chase seals, seals, walruses, dolphins and other marine animals in groups, and even attack large baleen whales. Female killer whales give birth to 1 cub every five years, and can give birth to 5 cubs in their lifetime. The life expectancy of men is 50-60 years, and that of women is 80-90 years.
Black whale is a highly socialized animal, which can form a family and is the most stable family in the animal kingdom, with complex social behavior, hunting skills and voice communication.
In the ocean, killer whales are "marine killers", ranging from fish, squid and turtles to sea lions, seals and even fin whales and sperm whales. Therefore, killer whales are also called "killer whales". The pollution of marine environment and the killing of killer whales for aquarium trade have seriously threatened the survival of killer whales, which have been listed as the second-class protected wild animals in China.
