| Abstract | Despite its common name, the green crab Carcinus maenas (Linnaeus, 1758) ranges from green through orange to red coloration on the ventral surface. In the literature, crabs have been lumped into two color groups, green and red (Reid et al., 1997). For the rest of this paper, green crabs will refer to any C. maenas, while green phase and red phase will refer to individuals of each color category. In male crabs, the red coloration, which develops during prolonged intermolt, is associated with several ecological and physiological changes in the crabs (see Reid et al., 1997; Styrishave & Andersen, 2000 for reviews). Red phase crabs are more common in subtidal habitats than in intertidal or estuarine, in both European (Crothers, 1968; McGaw & Naylor, 1992a; Hunter & Naylor, 1993; Reid et al., 1997) and New England (McKnight et al., 2000) populations, in a large part due to their narrower physiological tolerances when compared to green phase crabs (Reid & Aldrich, 1989; McGaw & Naylor, 1992a, b). Red phase individuals have thicker carapaces, more robust chela muscles, and are stronger than similar-sized green phase individuals (Kaiser et al., 1990). These size and strength differences result in higher mating success for red phase males when compared to green phase males, in both eld and laboratory experiments (Reid et al., 1997). A trade-off exists between mating success and physiological tolerance. Reid et al. (1997) suggest that the color phases are part of an evolutionary stable |
