Mermaid Syndrome (Sirenomelia)
A Peruvian baby dubbed the “Little Mermaid” because she was born with a rare condition in which her legs are fused. Nine-month-old Milagros Cerron – her name means miracles in Spanish – is one of only a handful of the estimated 1-in-60,000 to 100,000 people born with sirenomelia, or mermaid syndrome, to have lived more than a few hours, experts say.

From the waist up, Milagros smiles and babbles like any healthy infant. Below the waist, her stomach merges seamlessly into her legs, which are joined all the way to her heels. With her tiny feet splayed in a ‘V’, the impression of a mermaid’s forked tail is complete.
