What rare condition is referred to as the mermaid syndrome due to the legs being fused together at birth?

This is called "Sirenomelia". (Daryl Hannah had this when we were dating, and she made a movie )

P.S.: Hi Georgia!!!

Well aren't you a smarty!

LIMA, Peru (Reuters) - Ricardo Cerron is fed up with people staring or even laughing at his baby, dubbed Peru's "Little Mermaid" because of a rare birth defect in which her legs are joined together.

Cerron, a 24-year-old mechanic, was so desperate when his daughter was born with "mermaid syndrome" -- a condition called sirenomelia, which is nearly almost fatal -- that he appeared on television to appeal for help.
