“These hermit crabs at low tide are ordinarily stranded all over the sandy beach. But if this 
happens during the hours of sunshine, they move into the shadow of the vegetation the shore offers. 
It is peculiar that only a few places are selected to which a great number of them come apparently for the 
same reasons. The photograph shows one of these heaps of hermit crabs benefited by the shadow of the 
tall and partly overhanging shore grass.”’ (H. L.)
