What other animals can have twins?

Identical twins, although rare, do occur in other animal species, including horses, cattle, pigs, and even armadillos. In some of these species, the occurrence of identical twins often comes the concern of conjoined twins, most notably in cattle.

What animals have multiple babies?

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.

Which monkey always has twins?

What animal is your twin?

Do gorillas have twins?

How often are twins born? Of the more than 270 births that have occurred in the Karisoke gorilla groups over the last 50 years, only three have involved twins.

Can monkeys have twin babies?

Twins are extremely rare among many primates such as Old World monkeys, because each baby takes a lot of time, energy, and food to rear. Thus, scientists were pleasantly surprised to record the first instance of twins born to a wild group of stump-tailed macaques, in a hilly, forested area in central Thailand.

Can cats have twins?

It's actually rare for cats to give birth to identical twins, when they are lookalikes it's usually because they share the same mother and father. It's even quite possible for kittens in the same litter to be half brothers and sisters as mum may mate with more than one tom cat.

Are all armadillos twins?

“Uniquely among mammals, armadillos always have genetically identical quadruplets,” said CSHL computational biologist Jesse Gillis.

Which animal almost always gives birth to identical quadruplets?

Nine-banded armadillos almost always give birth to four identical quadruplets.

What mammal can have the most babies at once?

Humans have been known to give birth to up to eight babies at any one time, but that doesn't even bring us close to the biggest mammal litters. Probably the Tailless Tenrec (Tenrec ecaudatus) of Madagascar, although it depends how you measure it.

Can horses have twins?

Rare Case All Around

Treasure and her duo is a rare case. In horses, twin fetuses are uncommon. Carrying them to term is even more unusual, and birthing healthy twin foals is especially unlikely. “Twin pregnancies are extremely undesirable in horses, as they almost always have a bad outcome,” said Dr.
