Behavioral responses to burial in the hermit crab, Pagurus samuelis: Implications for the fossil record
JA Shives, SG Dunbar - Journal of Experimental Marine Biology and …, 2010 - Elsevier
The intertidal hermit crab, Pagurus samuelis, was subjected to various treatments analyzed
to determine behavioral responses to the ecological stress of burial. Hermit crabs were
buried at varying depths (2, 4, and 6cm), and in two orientations (shell aperture up and
aperture down). Hermit crab weight, shell weight, shell shape, aperture orientation, and
depth of burial were analyzed to determine their influence on shell abandonment and
survival. We found a significant number of hermit crabs that abandoned their shells when …
