Derceto is the goddess of fertility, but is a mermaid. Being able to breathe on land and water is yet a privilege that a fertility goddess such as her should take advantage of. She is like many other fertility goddesses, but she has a mermaid appearance.
Derceto adores all animals, and doves often come to her aid. She likes to take small naps around the sea beds and around shallow lakes to be near and connected with the forests and streams.
