Medium ones about the size of a golf ball may molt every four to six months and stay buried for about one to three months. The smaller hermit crabs may molt as often every month or even every few weeks for the tiniest ones, and may stay buried to do it for only a couple of weeks or months.
Most horseshoe crabs will not even make it to the larval stage before being eaten. If the egg survives, the larval horseshoe crab will hatch from the egg after about 2 weeks or more. The larva looks like a very tiny version of an adult horseshoe crab without a tail. Larval horseshoe crabs travel into the ocean water and settle on the sandy bottom of the tidal flats for a year or more.
