Two-headed animals and three-headed animals are the only type of multi-headed creatures seen in the real world, and form by the same process as conjoined twins from monozygotic twin embryos. In humans, there are two forms of twinning that can lead to two heads being supported by a single torso. In dicephalus parapagus dipus, the two heads are side by side.

Survival to adulthood is rare, but does occur in some forms of dicephalus parapagus dipus. There are many occurrences of multi-headed animals in mythology.
