Compared to all my other critters, Gigantor took the longest time to prepare to the point that I would feel really impatient and anxious: "What if the substrate is not moist enough? Are the conditions perfect for molting? What if he molts overnight and one of the large crabs eat him in all his naked glory?" You know, the usual crab enthusiast questions.
Anyway, I also noticed that Gigantor (as well as the other crabs except PP), would burrow themselves halfway and would stay that way for several minutes. I don't know why, but I noticed that since June rolled in they've been doing that pretty regularly.
This is what I meant:
He looks like he's checking out the sand or airing out his shellWell anyway, finally after a few days/weeks of burrowing and resurfacing, Gigantor finally molted last night:
And of course, ye old exoskeleton:
Only Hercules left! He should be molting pretty soon :)
