Mister Mac Little did I realize when I posted this that it would generate such “critical” acclaim. I will leave it up to historians to decide which is which. One caveat: Like all good Naval Yarns that are passed along, this one probably has some elements of truth to it and some conjecture. But there is a part of me that will always be a part of a very unique family known as Submariners. I am proud of the American flag and I am a humble servant of the Risen Lord. I can’t speak for all submariners, but it is certainly true for me. I have heard many times that once you wear the dolphins, they are forever emblazoned into your heart. Submariners have a quirky sense of humor which can either be endearing or annoying depending on who is on the receiving end of their brand of humor. I’ve always had a sneaking suspicion that the name fish came from a smartass Submariner who was making a snarky comparison to the men who were fishy enough to volunteer to be locked up in a steel tube that submerges for extended periods of time.

They also have blowholes and must return to the surface for air. That’s interesting in some ways since a dolphin is a mammal and not a fish.ĭolphins of course are mammals because they have all of the major characteristics of mammals they breathe through lungs, they are warm-blooded, they produce milk for their offspring and they have hair. The common name for the insigne is Dolphins although in my time, they were also known as “Fish”. I have seen many stories over the years about the origin of the insigne but this article from the Navy’s All Hands Magazine seems to sum it up nicely. Officers wear a gold version and enlisted wear a silver version. It is likely that more (or fewer) differences between dolphins and porpoises will be revealed as researchers continue to investigate these intriguing sentinels of the sea.One way to distinguish a United States Navy Submariner from any other sailor is to see the dolphins predominantly displayed on his or her uniform. Both have large, complex brains and a structure in their foreheads, called the melon, with which they generate sonar (sound waves) to navigate their underwater world. Scientists are pretty sure that porpoises do not do this, and some think this may be due to structural differences in the porpoise’s blowhole.ĭolphins and porpoises have many similarities, one of which is their extreme intelligence. Dolphins make whistling sounds through their blowholes to communicate with one another underwater. Generally speaking, dolphin bodies are leaner, and porpoises’ are portly.ĭolphins are also more talkative than porpoises.

The dolphin’s hooked or curved dorsal fin (the one in the middle of the animal’s back) also differs from the porpoise’s triangular dorsal fin. Dolphins tend to have prominent, elongated “beaks” and cone-shaped teeth, while porpoises have smaller mouths and spade-shaped teeth. So what’s the difference? It essentially comes down to their faces (who can forget Flipper’s famous “grin”?), their fins, and their figures. The dorsal fin is small and triangle-shaped. The harbor porpoise has small pointed flippers and no beak.
