Residents of a community in Bauchi State have been left in shock after a woman was delivered of a baby with four legs.

It was gathered that the baby was born with a parasitic twin, a smaller and less-developed twin attached to the upper part of her abdomen or chest.

According to reports, the baby is set to undergo surgery to remove the extra limbs from the body.

A parasitic twin is an identical twin that has stopped developing during gestation but is physically attached to the fully developing twin.

The fully developed twin is also known as the dominant or autosite twin.

The parasitic twin never completes development.
