Dolphin spermatozoa are capable of penetrating zona intact bovine oocytes and producing hybrid embryos.
Dolphins sometimes try to mate with other animals, including human scuba divers and sea turtles. There are cases of a hybrid between a dolphin and a false killer whale (both are actually dolphins, but they're different species). This offspring is known as a wholphin (whale and a dolphin).
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).
Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
In fact, such human-animal hybrids are often referred to as “chimeras”.
We Have Very Similar Genetics
Throughout studies, geneticists have found that the human genome and the dolphin genome are basically the same. Texas A&M Scientist Dr. David Busbee explains, “It's just that there are a few chromosomal rearrangements that have changed the way the genetic material is put together.”
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.
The only other known animal to experience pleasure during sex is the female Japanese macaque, which has been observed orgasming - despite there being no direct reproductive benefits.
Gender Differences
Dolphins have no secondary sex characteristics. The only way to determine a dolphin's gender in the wild is to see a clear view of their genitals, or to observe an erection, act of intercourse, or a baby swimming close to an adult presumed to be a female.
Either way, they do. And sometimes they have babies. And now scientists have spotted one in the waters off Hawaii. At this stage the wholphin is thought to be the first product of a union between a rough-toothed dolphin and a melon-headed whale.
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.
Creatures big and small
Most animals that procreate through parthenogenesis are small invertebrates such as bees, wasps, ants, and aphids, which can alternate between sexual and asexual reproduction. Parthenogenesis has been observed in more than 80 vertebrate species, about half of which are fish or lizards.
Q: In the wild, how do dolphins copulate? A: It's very variable. Some species, like dusky dolphins, copulate belly to belly. Bottle nose dolphins seem to make a T-formation, where the male crosses the female exactly at her midline.
Different forms of self and partner genital stimulation have been observed in the animal kingdom. Oral sex has been observed throughout the animal kingdom, from dolphins to primates.
a) Dogs and cats are not like people when it comes to sex. They don't cycle the same way and there's no evidence, behaviorally or otherwise, that sexual activity brings them any specific pleasure akin to orgasm, for example.
Shark-dolphin hybrids are impossible. It's true that sharks and dolphins look similar in many ways, but that's because they are a product of convergent evolution, where two genetically distant animals who live similar lifestyles start to look and act in similar ways. But sharks are fish and dolphins are mammals.
The liger, offspring of a male lion and a tigress (a male tiger and a lioness produce a tigron), is just one of many examples of cross-species hybrids. Sheep can breed with goats, horses with donkeys, and chickens with peafowl. Indeed, many of our garden and crop plants were created by crossing different wild species.
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.
A dolphin's sound waves created for echolocation may be able to detect the presence of a fetus in a body. To do this, a dolphin must be familiar with the person so it can sense a change in the person. Trainers are a good example of people who report this type of pregnancy detection.
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.
Although figures vary from study to study, it's currently generally accepted that chimpanzees (Pan troglodytes) and their close relatives the bonobos (Pan paniscus) are both humans' closest-living relatives, with each species sharing around 98.7% of our DNA.
The chimpanzee and bonobo are humans' closest living relatives.
"Sea urchins don't look any more like humans than fruit flies, but about 70 percent of sea urchin genes have a human counterpart whereas only about 40 percent of fruit fly genes do."
