Description

Last night in Rhode Island, we counted over 100 crabs coming ashore to mate. We found many more males than females, and the males were mostly smaller (18-23cm wide) than the females (22-25cm wide). Many males tried to push others off the females, while the females lay half buried in the sand laying eggs.

Description from Wikipedia

Merostomata is the name given to a grouping of the extinct Eurypterida (sea scorpions) and the Xiphosura (horseshoe crabs). The term was originally used by James Dwight Dana to refer to Xiphosura only, but was emended by Henry Woodward to cover both groups.
