eli5 Why do pigs have that strange tail, why it is not straight?
In: Biology
Pigtails like other tails move through muscle tension. This indicates the mood of the animal in addition to being useful for things like balance or gripping etc. Like dogs, pigs will reflect their emotional state through their tails. A curled tail often indicates a content pig. A hanging tail can indicate low mood and health issues. The tail curls on its own and no curling is needed. Farmers absolutely do not do that. What farmers do is dock the tails of pigs so other pigs wont bite at them. Distressed pigs tend to lash out and hanging tails are just within striking distance.
