Hermit crabs are marine crustaceans that must inhabit empty gastropod shells for shelter and protection from predation, desiccation and osmotic stress. In New England, the hermit crab (Pagurus longicarpus) commonly occupies two different types of...
Geographic variation in phenotypic traits among conspecific populations is well documented. Some studies have revealed that prey species may be induced to develop a defensive morphology when exposed to a specific predator. Interestingly, few...
