More about this crab on the wildfacts sheets on wildsingapore.  I came across this pair of mismatched moon crabs, I'm not really sure what is going on here. Mating? Moulting? Before I could take a closer look, the pair (still clinging to one another) paddled off with the next wave.  For a high res version of this photo, please review the details on about using my photos.
