Dolphins Reproduction

Do you want to know about a dolphin’s reproduction process? On this section of Dolphinaris Encyclopedia, you can learn about dolphins mating behavior.

Sexual maturity

Dolphin’s reproduction maturity is variable among bottlenose dolphins. On average, males reach sexual maturity at about 11. Females reach sexual maturity at about 5-7. The genitals are concealed in both males and females, but they can be sexed if you are able to catch a glimpse of their belly. Both sexes have a naval and genital slit, but the females also have a mammary slit on either side of the genital slit.

Mating activity

Females seem to be sexually receptive during a large part of the year and are generally responsible for initiating courtship and breeding behavior. There is no breeding season for dolphins. They breed 365 days a year. Just before mating, a male rubs and nuzzles a female. He may also exhibit an "S-curve" posture, in which he lifts his head up and points his tail flukes down.
