Pagurus bernhardus forgaing within the sand. Hermit crabs are limited by their shell size. Makes sense right? The bigger the she, the bigger the individual is able to grow. Hermit crabs display high levels of cannibalism and will often feed on individuals that are moulting. In order to moult the individual must leave its shell and gulp in water to expand the exoskeleton. A lot of moulting is controlled by specific hormones. Measuring these can indicate environmental stressor s and give indications as to the overall health of an individual
This is a one of many photos taken by the talented @nordic_diver and I've been lucky enough to showcase them on my IG.
