Hermit Crab Equipment
"So, I never really thought I'd study penis size, but I sort of stumbled on this topic." Mark Laidre, a biologist at Dartmouth College. Laidre travels to Costa Rica to study hermit crabs, a species called Coenobita compressus. These land crabs do some interior remodeling of their adopted shells: they extensively hollow them out, removing struts called spiral columella, to give themselves some extra elbow room. The renovation renders the shells more precious to their owners - and to other covetous crustaceans as well.
