Is A Crab An Endolithic Biome

Symbiotic endolithic microbes alter host morphology and .

Endolithic bio‐erosion appears to ameliorate radiative heating on mussels and thus reduce subaerial heat stress on mussels. Infestation is highest in the upper intertidal where mussels spend the longest time exposed to the sun. The high mortality rate of non‐infested mussels during heatwave events suggests that erosion may be a pre .

Postmortem changes in strength of gastropod shells .

Calliostoma ligatum shells inhabited by hermit crabs were weaker than shells inhabited by snails collected at the same locality. When shells of C. ligatum were loaded repetitively to 80% of their predicted failure load, hermit crab-inhabited shells showed an immediate drop in shell strength followed by a progressive further loss of shell strength over the next 18 days.

One result of this is the development of endolithic and chasmolithic communities, which are completely confined to the north faces of suitable rocks (Friedmann 1982). Mosses and lichens that grow in mesic areas where meltwater is the main supply may face very high light levels when active.

Of course you wouldn't take a spiral shell that already had a living hermit crab in it, but by taking empty spiral shells from the beach you are depriving those same hermit crabs of their next home. As hermit crabs grow, they must move into ever larger shells. If a hermit crab can't find a larger shell, it will die of exposure or predation.
