Two-headed animals – Polycephaly

Animals with two, three or more heads

Mythological creatures, fighting for good or evil, were at least unusual in appearance. They were often a combination of several animals, had several tails, limbs, sometimes several heads. And we are going to write about multi-headed animals in this article. However, we will not only write about legendary creatures, but also about real cases of animals that were born with more than one head. We do not want to make a sensation out of it, so we will spare you detailed descriptions. However, we would like to make you aware that cases of polycephaly are real. Unfortunately, it does not only apply to animals, but also to humans. Two-headed animals (called bicephalic / dicephalic) and three-headed (tricephalic) animals are the only types of multi-headed creatures seen in the real world. They are formed by the same process as conjoined twins from monozygotic twin embryos.

In this article, we will describe the phenomenon called polycephaly. It is therefore a condition, in which one body has more than one head. There are other varieties, similar to polycephaly, but due to their specific characteristics, they have separate nomenclature. We are talking about, for example, Craniopagus parasiticus – a type of Siamese twins. However, we will not describe this phenomenon in humans, because these are rather unpleasant cases, and we are not lovers of peculiarities circuses.

The most common two-headed animals are reptiles – turtles and snakes. This phenomenon also occurs in mammals (cattle, pigs, cats, dogs), fish and birds. Therefore, it applies to almost all groups of animals.

Examples of two-headed animals


A two-headed turtle was found in a pet store in Florida (USA), which is also an animal protection organization. The store owner claimed it was brought by a man who saved the turtle’s eggs after hitting a female turtle with a car. The animal’s condition began to deteriorate, so he turned to Sean Casey, the store owner, for help. The reptile was cured and a shop became his home.

Usually, turtles which were born deformed, do not live long. Casey, however, claimed that this particular individual could live up to 100 years.

Each head had to be treated delicately and fed separately. If only one food was given or placed in front of the turtle, fighting ensued.

Ultimately, the animal was stolen from the store, and it is unknown what happened to it.
