It comes just months after pictures of a similarly-deformed piglet were taken in the village of El Galpon, in the north-western Argentine province of Salta.
The latest image was snapped by the Murillo family who have a pig-rearing business in the coastal city of Los Mochis in Mexico’s north-western state of Sinaloa.
The farmers said they were shocked when they discovered the newborn piglet and decided to share an image of the animal online, where netizens started widely sharing it.
It was also published in several local news outlets. The Murillos said that they had never seen anything like it and they thought that two piglets had actually somehow fused together in their mother’s womb.
The little black-spotted creature, which only had one head but two bodies, was very weak and reportedly died just minutes after being born.
This incident is just the last in a string of similar cases where deformed animals are being born in farms across Latin America.
In Argentina, local media coined the term the ‘Spider-Pig’ for a similar piglet that had also been born with eight legs.
Experts quoted in reports believed the deformities were due to an excessive use of pesticides used on genetically-modified food fed to farm animals.
Animal rights activists believe it is due to the industrial chemicals that the farmers are said to have used on their land or possibly the side-effect of intensive farming techniques.
