Dolphins can breed in the suitable breeding season. First of all, it should be clear that although dolphins live in water like fish, they are not fish, so it can not be considered that the reproductive mode of fish oviposition is also suitable for dolphins. Dolphin is a kind of mammal, the way of reproduction with other mammals have a lot of similarities, they are viviparous way to reproduce.
In the specific breeding time, the female dolphin will mate with the male dolphin first. After mating, dolphins wait a long time to give birth, about 11 months, sometimes longer than human pregnancy. As mammals, dolphins also need to suckle. After the lactation period, the calf stays with the female until it has learned predation and other important survival skills before leaving the mother.
As mentioned above, dolphins are not fish, so the reproductive mode of fish oviparous is not the reproductive mode of dolphins. As a mammal, dolphins use viviparous reproduction. Dolphin pregnancy is relatively long, similar to human pregnancy, sometimes even longer than human pregnancy. After pregnancy, dolphins will give birth to small dolphins directly, the tail of small dolphins will be exposed first, different from the human head first. After that, they will go through the process of breast-feeding. The calf stays with its mother for a long time, and in the process, other dolphins in the group will also protect the newborn calf.
