Niche construction and its consequences in terrestrial hermit crabs.
(A) Empty gastropod- vs. hermit-derived shell (left and right, respectively). Red arrows show opening diameter. (B) Poor fit of hermit inside gastropod-derived shell. (C) Precise fit of hermit inside hermit-derived shell. (D) Opening diameter (mean ± se) of gastropod- vs. hermit-derived shells, relative to diameter of hermit abdomens. (E) Percent survival after 24 h for hermits allocated to gastropod- vs. hermit-derived shells.
