A mother has given birth to a baby with a human tail.
Fascinating pictures published in a medical journal show how the appendage had a ball-shaped mass on the end.
All babies develop an embryonic tail in the womb between four to eight weeks after gestation, but this is normally reabsorbed back into the body.
But in extremely rare cases, this doesn’t happen and the tail can continue growing.
By the time he was born, the tail had grown to a whopping 12cm, and developed a 4cm diameter ball at its tip.
Doctors who examined the baby noted the tail contained no parts made of cartilage and bone, meaning it was a rare example of a true human tail.
