Polycephaly is the condition of having more than one head.
Two-headed animals (called bicephalic or dicephalic) and three-headed (tricephalic) 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.
While two headed snakes are rare, they do occur in both the wild and in captivity at a rate of about 1 in 10,000 births.
Most wild polycephalic snakes do not live long, but some captive individuals do. A two-headed black rat snake with separate throats and stomachs survived for 20 years.
Why does this seem to happen to snakes so often compared to other animals? I mean, you don’t see this happen to dogs or cats very often but snake embryos seem almost eager to mix it up every once in a while and pull a two-for-one deal in the head department.
The consensus seems to be that polycephaly occurs more often in reptiles than other animals, but the why of it, as far as I could find out, is relatively unknown. Polycephalic animals appear so infrequently and they survive for such a short time that scientists just have not been able to study them sufficiently. If anyone can find more information about why it happens more often in reptiles, feel free to chime in. In the meantime, enjoy these two-headed lizards and turtles:
Can you imagine the arguments!
One thought real quick: two-headed dinosaurs
oh my god i will lose my fuckin mind the day that fossil is found
@magicturtle two headed dinosaurs seems like something you’d be down for.
Franco has home in the southern part of Switzerland, in a cosy village close to Lugano Lake.
He is one of the most appreciated photojournalist specialized in underwater subjects and stories.
Franco began to dive in the 1981, in the Lake of Lugano. At the
beginning, he dived the fresh waters nearest home, especially lakes and
rivers, where the water is clearer and he was able to improve his
photographic technique.
Then he travelled everywhere he could, documenting wildlife and human
relationship with nature in environments from the Equator to the Poles.
Franco dived in all the oceans of our Earth : Pacific Ocean, Atlantic,
Indian, Arctic, Antarctic, Mediteranean Sea, Red Sea, improving his
skill as photographer and his love for wildlife and conservation of
biodiversity, flora and fauna.
