a sea lion is a mammal that lives in the sea. After mating, sea lions have a long gestation period, nearly a year. Sea lions can only produce one pup per litter. Newborn small sea lions are relatively large, body length can even be close to 1 meter, weight can reach 20 kilograms or more.
Because sea lions are mammals, they have a period of lactation after giving birth, during which the mother sea lion will always take care of the baby sea lion and feed it breast milk. Sea lion breast milk contains more nutrients, especially fat, than human breast milk contains a lot more fat. Therefore, during lactation, the growth rate of young sea lions is very fast.
Sea lions need to reach the right age to breed, that is, they must be sexually mature before they can breed. Specifically, the age of sexual maturity of sea lions is 3-5 years old, precocious sea lions mature at about 3 years old, and late-maturing sea lions generally have the ability to reproduce at about 5 years old. After sea lions become sexually mature, they will breed in the appropriate breeding season, specifically from May to August. During this period, a male sea lion and a number of female sea lions will form a group to breed and mate.
