Differential coloration patterns in the intertidal crab Neohelice (=Chasmagnathus) granulata
Many crustaceans with spatial segregation may present differential body coloration depending on the habitat they inhabit. Since crustaceans are unable to synthesize carotenoids, individuals must acquire them from their diet, so diet changes can modify individual coloration. The burrowing crab Neohel...

Many crustaceans with spatial segregation may present differential body coloration depending on the habitat they inhabit.
