"Claw waving display changes with receiver distance in fiddler crabs, "Post-larval development and sexual dimorphism of the spider crab, "Larval Release Rhythms of Decapod Crustaceans: An Overview", "Diel and tidal cycles regulate larval dynamics in salt marshes and mangrove forests", New South Wales Department of Primary Industries, "Systema Brachyurorum: Part I. These groups can have hundreds or even thousands of crabs in them. Regulating the amount of crab caught each season helps to control their numbers and make sure that crab continue to be around in the future.
