Project Noah is a tool to explore and document wildlife and a platform to harness the power of citizen scientists everywhere.
These seem to be a darker color phase than the males I spotted previously:
CDF of the Galapagos: Are these females or juveniles?
Yes, these guys are fascinating. I worked on them half a century ago. For some info look at http://www.darwinfoundation.org/datazone... or http://www.ncbi.nlm.nih.gov/pubmed/55977.... My basic paper is long - and in German, though.
beauty ! nice shot dear
Thank you for the info! These crabs were really neat to observe and photograph. One of my favorite animals from my Galapagos trip!
I would guess this is a female, because I don't see bristles on the front walking legs and ther claws are relatively small. But it also could be a half grown male. The only way to be sure, as with all crabs, would be to look at the abdomen, which is narrow in males and wide in females.
