In males, the body size at which the allometric shift in cheliped size (CW, 64.
The allometric status of each studied variable are shown: carapace length (CL), length of the propodus of the major cheliped (ChL), width of the abdomen at the level of the junction between the fourth and fifth somite (AW), length of the left pleopod (PL), length of the merus of the left first walking leg (1 L), and length of the merus of the left second walking leg (2L).
The first immature or juvenile phase and the second prepubertal phase are separated by a prepubertal critical molt, after which the level of allometry of the chelipeds and gonopods (modified pleopods) in males and the abdomen in females increase substantially (Hartnoll 1965, Hartnoll 1974, Hartnoll 1978, Allunno-Bruscia & Sainte-Marie 1998).
Leurocyclus tuberculosus, Mithrax tortugae), males and females exhibit only 2 distinct postlarval ontogenetic phases distinguished by the level of allometry and relative size of the abdomen and chelipeds in females and males, respectively (Baron et al.
In brachyuran crabs, including spider crabs from the Mithrax-Mithraculus species complex, the first pair of pereopods bear large chelipeds that serve as weapons during interand intrasexual interactions (Hartnoll 1965).

opilio with large cheliped and large body size are at a competitive advantage over smaller males when courting (Comeau and Conan, 1992; Sainte-Marie et al.
