- The Seahorse in the HCMM Crest
The sea-horse is an emblem of safe travel, particularly by sea. The heraldic sea-horse, however, does not resemble the natural seahorse at all. It is an imaginary creature with the head, chest and forelegs of a horse, webbed feet like a frog in place of its hooves and a scaled body that flows into the large powerful tail of a fish, which if properly drawn, circles around itself in a coil. The mane may or may not be scalloped. It is a popular symbol found quite regularly in heraldry.
