in which Sc ecosystem is a horseshoe crab found
Horseshoe crabs are a keystone species within the Delaware Bay ecosystem. Description: Horseshoe crabs look like prehistoric crabs. They have a hard exoskeleton, ten walking legs under the shell, spines on the abdomen and a long tail.ost 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.
