OK, This may be nothing but this is spooky because for completely unrelated reasons I just subscribed to a machining youtube channel run by a former NAVY guy. Just this morning I watched one of his videos from a few months ago talking about casting brass plaques for submarines and the subject of DOLPHINS and their historical significance in the submarine services
>The insignia of the U.S. submarine service is a submarine flanked by two dolphins.
>Dolphins, attendants to the Poseidon, Greek god of the sea and patron deity to sailors, is sometimes referred to as the sailor's friend. They were also chosen to represent the Submarine Service because of the characteristic way in which dolphins dive and surface.
