Triton Himself

Triton is a merman in Greek mythology, He's the messenger god of the deep sea and a trumpeter of the sea, but he is also the son of Poseidon and Amphitrite. He has a conch shell which he used as a trumpet in order to tame the waves to his volition. Gradually, his name Triton started being used to describe a class of creatures similar to mermaids and of either sex, who served as followers of other sea deities. The Triton's were considered to be the trumpeters of the sea. Sometimes, they were also considered the equivalent of satyrs in marine environments. 

Triton had great power that could move whole lands and calm seas.

As he was a son of Poseidon and Amphitrite he was still living with them in a golden palace in the depths of the sea. In the mythical lake Tritonis, near the Mediterranean coast of Libya. He was represented as man in his upper parts, terminating in a dolphin's tail; but his special attribute is a twisted sea-shell, on which he blows, sometimes violently, sometimes gently, to either raise or calm the billows. In time there grew up the notion of a large number of Tritons, all represented as beings of double form and sometimes with the fore feet of a horse as well as a human body and a fish's tail called Centaurs.
