@Jennyncmg I wasn't photographing these for NatureMapr at the time. Strange, I thought most of the sightings I'm currently adding, were already added back in the year thay were taken. Some records are there but most aren't.

Shame there is not another photo of the upper side of the crab's cast off outer skeleton. It was a female as the abdomen flap is wide and rounded.
