Hermit crabs are crustaceans with soft abdomens. Hermit crabs protect their abdomens from predators by salvaging empty seashell (gastropods) and occupying them. The species diversity of seashells used by two species of hermit crab (P. pubescens and P. bernhardus) was sampled at three sites (T1, T2, T3) in northern Norway. These data are presented as species accumulation curves in the figure to the right. A. Have researchers adequately sampled each species of hermit crab to fully characterize the diversity of shells they use? P. pubescens – Yes or No (circle one) Why? P. bernhardus – Yes or No (circle one) Why? B. Do the species differ in the diversity of the seashells they use? Explain.
