Dead on beach
Observed different age crabs. Found 6 molts but saw 5 others that were in the muck that prevented collection. Numerous crab trails in the sand. Observed fewer crabs than on June 29, 2016- counted 400 crabs
We counted 179 of these. 55 were single, the rest were mating. 51 makes, 4 females of the singles.
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.
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.
