Giant statue sighting in Hamburg

Am I the only one who finds this sculpture a bit odd?...I mean,Its a giant sculpture of a woman spreading her legs in the middle of nowhere...And if its a mermaid as everyone is calling it..why does it/she/whatever have legs?

'mermaid' sculpture created by Oliver Voss on Alster lake in Hamburg in the late evening August 3, 2011. The four-metre-high sculpture dubbed "Riesen-Nixe" (grand mermaid) or "Badenixe" (bathing beauty)
