This name derives from the Ancient Greek “Thálassa (Θάλασσα)”, meaning “sea, the Mediterranean Sea, channel, salt water”. In Greek Mythology, Thalassa was a personification of the sea. Aether and Hemera were her parents. She's called the mother of Aphrodite by Zeus. She was the wife of Pontus and the mother of nine Telchines, who are known as fish children because they have flippers for hands; yet, they have the head of a dog. In some Greek stories, she is known as the mother of all. "Thalassa even goes by fish mother" This name is not only because she bore Telchines, it's also because she is creator of all sea life.
