Triton was the son of Poseidon. In the film Jason and the Argonauts, Triton helps protect Jason from two cliffs caving in, under Hera's command, after the blind prophet gave Jason a necklace resembling the sea God. Triton was a fish-tailed sea god who could still the waves with the blow of a conch-shell trumpet. Triton was also described as the god of the giant, Libyan, salt-lake Tritonis. When the Argonauts were in danger he assisted them in finding passage from the lake back to the sea. Trtion was depicted in Greek vase painting as fish-tailed merman, sometimes bearded.
