Welcome to another edition of “Did You Know?”!!!
Did you know there are instances where rats have their tails all tangled up together and cannot separate? The entanglement can be quite permanent and the rats are forced to live joined at the tails. This situation is called a “rat king“. Some people don’t believe such a thing could happen but there are instances in which the remains of a rat king have been found. Though rare, specimens have found their way to museums for display. X-rays of some rat king remains have shown breaks in the tails where the rats were knotted up.
The interesting thing is, there is very little historical evidence of anyone seeing a rat king while all the rats were alive.
