It's very rare to see a horseshoe crab swimming because they hardly ever do. When they do swim, they swim upside down. The horseshoe crab has been around for 200 million years before the dinosaurs. They have 10 eyes, 10 claws, 7 pairs of legs, and blue blood. Their blood is highly valued in the medical industry and is worth $15,000 per quart. Fortunately, they are not endangered. They shed their exoskeleton regularly as they grow. . . #facehugger #itwantsyoutocomecloser #nope #strangerthanfictio
