Pinocchio Terribillis is classified as a Euarchontoglires of unknown order, meaning while everyone is positive the species is a supraprimate is doesn't really fit in with other members of that clade -- primates, treeshrews, lagomorphs, and rodents.
Paleopinotologists have found fossilized remains of Pinocchio Imnasis Nares, a widely accepted ancestor of modern Pinocchio, everywhere Homo Sapiens and Neanderthal are also found. This suggests a co-evolution of the species.
Of the many strange qualities they possess, the strangest is that species has always walked upright and moved with an odd jerky and swaying motion, almost as if they were held aloft by unseen strings. This is thought to be a deceptive adaptation to confuse predators by making their motion unpredictable.
Their flesh is an inflexible fibrous material without interior bones and a thin exoskeleton similar to the excretions of the shellac beetle. This exoskeleton overs their entire body except for their noses, which need to expand and contract, which is another amazing trait of these creatures.
It's not known why they evolved the ability to grow their noses by up to 1000% in length. It has been suggested it was a primary characteristic in sexual selection, but since all three genders possess the trait that argument was the source of much controversy until the discovery of the Pilton Pinocchio.
That specimen, having been swallowed whole by a saber tooth tiger, its nose grew to such lengths it shattered the predator's ribs from the inside out. Suggesting that the nose is similar to puff fish spines and the psychedelic ooze produced by some species of reptiles.
There are many folk tales about Pinocchio that are known to stem from ignorance and superstition. They do not spring forth from wood. They often seek shelter from predators within trees because their fibrous nature permits them to move through them as we do through water. Stories of carving Pinocchio out of wood are misrepresentations of fact. The Pinocchio was no doubt merely hiding when discovered.
They are also excellent mimics, surpassing Ravens and Parrots, and often imitate the play of species they observed to avoid attracting attention to themselves. Herds of Pinocchio have been seen to be 'playing' at being donkeys or small boys. As they mature, their mimic can become extremely sophisticated and permit them to pass as human children. Again, this is thought to be an evolutionary adaptation to better avoid predators, since human communities are more successful at elimination external threats to their communities safety, than herds of Pinnochio are.
There is still a lot more to learn about this amazing species, and many learnings and current thinkings may not persist through the rigors of scientific inquiry.
