Chemosensation in the Daily Life of Crabs (original) (raw)

The goals of this paper are twofold. One is to provide a means to access the literature that reports most aspects of crustacean chemoreception. The intent is not to provide a review or to assign credit for original discoveries. Several references appear in the literature section that are not cited in the text. These references are in important areas that are rapidly growing but not discussed here due to lack of space. The second goal is to outline my perspective on how chemicals affect the daily lives of crabs. I have taken liberty with the term crab and have included information from studies on true crabs, lobsters, shrimp, crayfish and hermit crabs. The message is that chemosensory input, when placed in the context of the environmental and physiological status of crabs, is a means of modulating daily activity. CHEMOACTIVE COMPOUNDS
