Pin Tortuga Plated

Plated Turtle Pin, made of rhodium-plated steel with a size of 18 mm

The most important feature of the turtle skeleton is that a large part of its vertebral column is welded to the dorsal part of the shell. The skeleton makes breathing impossible by movement of the rib cage; It is carried out mainly by the contraction of modified abdominal muscles that function analogously to the diaphragm of mammals and by pumping movements of the pharynx.2 The skull presents great characteristics of primitivism. Although they lack teeth, they have a horny beak that covers their jaw, similar to the beak of birds.
