Sirenomelia alternatively known as Mermaid Syndrome is a very rare congenital deformity in which the legs are fused together giving them the appearance of a mermaid’s tail.This condition is found in approximately one out of every 100000 live births (about as rare as conjoined twins) and is usually fatal within a day or two of birth because of complications associated with abnormal kidney and urinary bladder development and function.
