There is no prophet who lives in water. Prophets are human beings, and humans need air to breathe and cannot survive underwater.
However, some stories and myths feature figures associated with water, such as:
- Poseidon: In Greek mythology, Poseidon is the god of the sea, earthquakes, and horses.
- Neptunus: In Roman mythology, Neptunus is the god of the sea, freshwater, and horses.
These figures are not prophets, but they are powerful beings in their respective mythologies.
