Dolphins give birth to a single baby; the baby is usually born tail first (unlike most mammals) to minimise the risk of drowning. The birth can take a couple of hours. The newborn dolphin is fully dependent on his or her mother and suckles thick paste-like milk from her nipples until he or she is able to catch fish.
Calving. Calves are born in the water. Deliveries are usually tail-first, but head-first deliveries are also seen. The umbilical cord snaps during delivery. Sometimes an assisting dolphin may stay close to the new mother and calf.
Dolphins give birth to live young and do not lay eggs. They can get pregnant on average every two to four years once they're mature, although some species can have 5-7 years between births. Dolphin calves tend to stay close to their mothers for a few years before venturing off on their own.
In fact, marine mammals carry their babies in the same way as we do, in an amniotic sac inside the mother's womb. Indeed, whales and dolphins have internal fecundation, carry their babies, and give birth to live young.
After birth
In order to feed the newborn dolphin the mother will provide her child with a thick paste-like milk through her nipples, which her child will suckle from until it is able to hunt on its own. Because dolphin milk is thick it minimizes the possibility of the milk dissolving in the water.
Dolphin calves can swim from the moment they are born. When baby dolphins are born, they must immediately swim to the surface to take their first breath of air. But how do they know how to swim so soon? The answer is amazing: they learn to swim while they're gestating in their mothers' wombs!
Dolphins appear to have a special affection for pregnant women. They have been known to swim up to an expecting woman and make buzzing sounds near her stomach. This is thought to be because dolphins might be able to detect a pregnant woman's developing fetus by using echolocation.
Dolphins are rapists.
A group of dolphins will “kidnap” a female dolphin and take turns aggressively raping her. The rape can go on for weeks, during which the males in the pod smack the female with their tails, threaten her with aggressive movements and noises, and even chase her down if she tries to swim away.
Pregnancy. Recent research indicates that bottlenose dolphin pregnancy lasts about 12 months (Wells 1987). During this time, there is very little room in the uterus for a baby to develop. As a result, and to make birth easier, the tail fluke and dorsal are cartilaginous and are folded over in the uterus.
Dolphins mate via internal fertilization which involves males hooking onto the females to ensure reproductive success underwater. Wild dolphins produce one calf every 3 to 5 years, which is a long time compared to other animals. Female pregnancy, or the gestation period, can last approximately a year.
Abstract. The testes of sexually mature dolphins produce large quantities of sperm. Sperm are expelled in copious amounts of seminal fluid through repeated ejaculations that can occur within a short period of time.

Dr Motha, 43, has spent 20 years researching childbirth, and believes that dolphins can help a woman deliver with almost no pain by passing an underwater sonar messages of support. And Sarah agrees: "Giving birth in the Red Sea with the dolphins was the most wonderful experience of my life," she says.
Dolphins are not monogamous animals and do not typically mate for life. Atlantic bottlenose dolphins live in what are called fission-fusion societies, where pods are constantly changing in size and numbers. Some believe bonds between males are the strongest and most enduring in bottlenose dolphin societies.
The actual act of mating only lasts a few seconds, but there is lots of foreplay. Some foreplay is rather aggressive on the part of the male. Gangs of two or three male bottlenose dolphins will bond together to isolate a single female from her pod. The males will forcibly mate with her, sometimes for weeks at a time.
The science makes one fact undeniably clear: wild dolphins of some species are noted for seeking out social encounters with humans. The phenomenon of lone sociable dolphins – for whom human contact appears to substitute for the company of their own kind – is documented extensively in the scientific literature.
A wholphin (portmanteau of whale + dolphin) is an extremely rare cetacean hybrid born from a mating of a female common bottlenose dolphin (Tursiops truncatus) with a male false killer whale (Pseudorca crassidens).
It is sensationalized information that the animals become aggressive towards pregnant individuals - it is simply untrue. Dolphins' echolocation gives them the ability to detect if a woman is pregnant in the water, and the ability to see the baby and heartbeat.
“The clitoris of dolphins has well-developed erectile spaces, is highly sensitive to tactile stimulation, and is likely functional,” the study notes. The animals do experience pleasure when having sex, due to their “large” clitorises.
Is it ok to swim if I have my period? Yes. Absolutely. Dolphins do not have a sense of smell, nor are they attracted to blood in the water like sharks.
Calves are born between 39 and 53 inches long, and weigh between 22 to 44 pounds of pure underwater adorableness. How long does a baby bottlenose dolphin stay with its mother? Calves stay under mama's watchful eye between 3-6 years, learning how to hunt, avoid danger and navigate their territory.
Herman 's experiment is one of several recent studies providing evidence that dolphins are capable of self-awareness, an attribute previously attributed only to humans and great apes.
That being said, mother dolphins or “cows” are known to be extremely attached to their young and typically only will have one calf in a lifetime.
