Pin - Starfish
Beautiful pin for your jacket lapel. Starfish may well be the most unusual of the well-known creatures. This one is 2 inches in diameter and weighs 0.6 ounce.
They have no front or back: they can move in any direction without turning. Rather than using muscles to move their hundreds of tiny legs, starfish use a complex hydraulic system to move around or cling to rocks. If you've ever tried to pry a starfish off a rock, you know how effective its hydraulic system really is. Starfish don't have to make themselves symmetrical. They can rearrange their arms any way they please in order to wedge themselves into a small nook in the rocks.
