Has a fishman ever had a devil fruit power? What's a female fishman called? Have they been shown? Ambphibianmen

[Warmmedown]

There must be a fable in One Piece's universe about a fishman who ate a DF and then had to leave Fishman Island.

Also I swear they're amphibian men. Do they have lungs?

There are already two fishmen that have consumed Devil Fruits. Vander Decken and Jack.

 

[Symbiote]

There are female fishmen. Don't remember her name but Hachi tried to impress one with his Takoyaki stand.
