The poor pig, which is one of a litter of 11, has been described as looking like a cross between a human and something from the Alien movies
Farmer Laureano Escobar Arias said: 'I was shocked - it was a really terrifying experience. It looked like some kind of alien creature.'
However, local health officials have suggested that there are more earthly reasons for the pig's appearance.
We don't know for certain but it could have been caused by a genetic problem or by environmental pollution,' one commented.
A bit closer to home, pathologists are investigating a series of animal mutilations in Wales, with aliens once again the suspected culprits.
It is thought that the surgical-style injuries are too sophisticated for other animals to cause and once again bright lights were seen near the scene.
