Male
Probably the Tailless Tenrec (Tenrec ecaudatus) of Madagascar, although it depends how you measure it. Mammals can have very variable litter sizes, but as a rule, the maximum litter size is the number of nipples, and the average litter size about half that.
The moment a male hippocampus whitei, also known as a White's Seahorse, gave birth to around 100 offspring has been caught on camera at Sea Life Sydney Aquarium. The babies of this endangered species, similar in size to a grain of rice, emerged from their father's pouch.
Some mammals, such as mice, produce several babies at once. Others, such as elephants and humans, usually only have one baby at a time. Most unborn baby mammals get their food and oxygen from their mother's blood through a spongy organ called the placenta.
Top Mammal Baby-Makers
Sheep and goats produce 1 to 3 offspring per gestation on average and can produce two litters per year. Both species sometimes give birth to quadruplets and on rare occasions even more. Pygmy and Nigerian dwarf goats are especially likely to produce more than 3 kids per gestation.
Also knows as Platypus frogs, the female amphibian, after external fertilization by the male, would swallow its eggs, brood its young in its stomach and gave birth through its mouth.
Animals that reproduce asexually include planarians, many annelid worms including polychaetes and some oligochaetes, turbellarians and sea stars. Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation, such as gemmae in liverworts.
Seahorses and their close relatives, sea dragons, are the only species in which the male gets pregnant and gives birth. Male seahorses and sea dragons get pregnant and bear young—a unique adaptation in the animal kingdom. Seahorses are members of the pipefish family.
Women can reproduce for about half of their lifetime and can only give birth about once every year or so. So it makes sense that women can only have a fraction as many children as men. One study estimated a woman can have around 15 pregnancies in a lifetime.
Of course, scientifically it's not possible for a human to have sex with an animal and give birth to a hybrid creature, not matter how many demons are involved. Genetics just don't work like that.
With the exception of opossums and kangaroos, giant panda newborns are the smallest mammal babies compared with their mother's size.
Arctic Foxes hold an interesting record. They have the largest litters of any wild mammal in the world. While the average is 11 puppies, litters with 22 puppies have been recorded in Russia.
It depends on the animal. While the combination of long labor times, big infant heads, and narrow maternal hips is often cited as a particular challenge for human mothers, some other mammals face difficulties that may be just as painful.
The platypus (Ornithorhynchus anatinus) has a puzzling array of features. Not only does it have that iconic duck bill, it lays eggs like a bird or reptile but feeds milk to its young like a mammal.
Monotremes are a unique group of mammals that lay eggs instead of giving birth to live young. Found only in Australia and New Guinea, monotremes are a fascinating example of the diversity of life on our planet. There are only three species of monotremes: the platypus and two species of echidnas.
Genghis Khan is known as one of the greatest warriors in the history of the world, but that is not the only thing he is known for. He is also known for being the man who had the most kids in the world.
Danish astronomer Peder Horrebow and his wife Anne Margrethe Rossing had a total of 20 children. One of their sons, Christian Horrebow, born 1718, continued his father's astronomical studies.
Mariam Nabatanzi Babirye (born December 25, 1980) also known as Maama Uganda or Mother Uganda is the most fertile woman in the world. She has given birth to a total number of 44 children, 38 of whom are alive. As of April 2023, her eldest children are 28 years and the youngest are 6 years old.
The spiny dogfish shark can carry young for about two years, while basking sharks can do so for as long as three years. The frilled shark can wait 3.5 years before giving birth.
How many babies were born during the longest recorded human pregnancy? The longest recorded human pregnancy was 375 days, or just over 12 and a half months, according to Guinness World Records. During this pregnancy, a woman named Beulah Hunter gave birth to a healthy baby girl in 1945.
Slugs, starfish, and other creatures also switch gender when it works to their advantage. However, the cues that trigger the change vary from species to species.
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.
It's a phenomenon known as parthenogenesis, or more colloquially as virgin birth. SARAH ZHANG: So these were two females who each had a son where there was no father. GODOY: Without any sperm, wow. That's, like, amazing.
