Why are there dead horseshoe crabs on the beach?
The shells are molts. Horseshoe crabs grow by molting. As a Horseshoe Crab matures and increases in size, it will shed its old exoskeleton (outer shell or skeleton) and form a new, bigger one, leaving its old shell behind on the bottom of the bay. It’s surprisingly easy to mistake a molt for a dead Horseshoe Crab.
How often do horseshoe crabs molt?
