Triton (the moon) and tritons (the gastropods) are named after…Triton, a Greek sea god who was the son of Poseidon (king of the sea) and his wife Amphitrite (herself a daughter of the ocean titans Nereus and Doris).  Triton was portrayed as a mighty merman who carries a musical conch with which he calms the seas…or whips them into a frenzy.

Triton lived with his parents in a golden palace beneath the waves (according to Hesiod).  He has a few cameo appearances in classical mythology (most notably in the story of Jason and the Argonauts) but he is generally overshadowed by his mighty father.  In late antiquity and the Renaissance, Triton came to be a sort of progenitor of mermaids and mermen (a role which he occupies in Disney’s “animated film The Little Mermaid”).

Geologists know that oceans and seas are indeed ever-changing and protean.  Whenever I think of Triton, I imagine how the oceans of the world will be entirely different in a few hundred million years (just as today’s oceans are no longer the Tethys or the Panthalassic Ocean).  Neptune’s reign will end and the oceans and seas will change–and yet they will really be the same great world-sea as they have been since the beginning.
