Triton in Greek-(Τρίτων, gen: Τρίτωνος) is a mythological Greek god, the messenger of the big sea. He is the son of Poseidon, god of the sea, and Amphitrite, goddess of the sea, whose herald he is. He is usually represented as a merman, having the upper body of a human and the tail of a fish, "sea-hued", according to Ovid "his shoulders barnacled with sea-shells".
Like his father, Poseidon, he carried a trident. However, Triton's special attribute was a twisted conch shell, on which he blew like a trumpet to calm or raise the waves. Its sound was so terrible, that when loudly blown, it put the giants to flight, who imagined it to be the roar of a dark wild beast.
According to Hesiod's Theogony, Triton dwelt with his parents in a golden palace in the depths of the sea; Homer places his seat in the waters off Aegae. The story of the Argonauts places his home on the coast of Libya. When the Argo was driven ashore in the Gulf of Syrtes Minor, the crew carried the vessel to the "Tritonian Lake", Lake Tritonis, whence Triton, the local deity euhemeristically rationalized by Diodorus Siculus as "then ruler over Libya", welcomed them with a guest-gift of a clod of earth and guided them through the lake's marshy outlet back to the Mediterranean. When the Argonauts were lost in the desert, he guided them to find the passage from the river back to the sea.
