Sorry, I don't have one but I don't think it would be too difficult to replicate. Use a cheap plastic skeleton for the upper portion then shape the lower body portion out of chicken wire and monster mud it all. If you wanted to make the entire mermaid more skeletal, like this picture, you could still use a skeleton upper body and arms but make the lower body with a thin white plastic, perhaps milk jugs? Just cut out simple rib shapes and a tail. Just a suggestion.
