Is there an animal that is born pregnant?

The primary animal born pregnant is the aphid, a tiny insect that reproduces via parthenogenesis, where developing embryos inside the mother contain their own embryos, creating "telescoping generations" or "Russian doll" pregnancies where babies are born pregnant with their own babies. Other animals like axolotls can reach sexual maturity very young, while marsupials like swamp wallabies can have multiple pregnancies (embryos in diapause) at once, though not born pregnant in the aphid's sense.

Can human sperm get any animal pregnant?

No, human sperm cannot fertilize eggs of other animals to create viable offspring due to significant genetic differences, though in lab settings, human sperm can sometimes penetrate zona-free hamster eggs (a test for sperm function) because of shared molecular recognition systems like Izumo1 and Juno, but actual successful human-animal hybrids are not possible with current understanding and technology, despite historical attempts like the "humanzee".
 

Why can't female seahorses give birth?

Scientist think the reason the males give birth instead of the females is because seahorse babies are often eaten by prey and so having the male give birth allows the female to create more eggs to be fertilized without having to wait to give birth herself. Sharing the labor ensures survival of the species.

In the animal kingdom, the frilled shark holds the record, with gestation potentially lasting up to 42 months (3.5 years), though some accounts suggest even longer brooding periods for certain cephalopods. 

What animals are asexual?

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 mosses and liverworts.

Is there an animal that is pregnant for 3 years?

Yes, some animals have pregnancies that last around or even exceed three years, with the Frilled Shark holding the record at up to 3.5 years, while Black Alpine Salamanders can gestate for 2 to 3 years, adapted to cold, mountainous environments. These extended periods are due to slow metabolism, deep-sea living, or harsh conditions, allowing for the development of well-formed young.
 

What animal has the shortest pregnancy?

The shortest pregnancy in mammals belongs to the stripe-faced dunnart, an Australian marsupial with an 11-day gestation, closely followed by the opossum (Virginia/Water) at 12-13 days, both giving birth to embryonic young that develop in a pouch. Other very short pregnancies include the hamster (around 16 days) and rat (around 22 days) for non-marsupials, though marsupials generally have the shortest pregnancies due to giving birth to underdeveloped young.
