Abstract: Interspecific competition is often difficult
to measure due to the lack of a definitive limiting
factor for the two (or more) species. The
gastropod shell inhabited by a hermit crab represents
a very discrete, definable portion of the
ecological needs of every animal. A hermit crab
must have protection for its soft abdomen or it
will rather quickly be eaten. In addition, the
ritualized shell fighting behavior patterns of
hermit crabs (Hazlett, 1966a, 1966b, 1967)
offer an easily observed specific behavioral parameter
which reflects the extent of interspecific
vs. intraspecific competition for this ecological
factor.
