Sexual dimorphism in Periclimenes paivai, symbiotic with the jellyfish Lychnorhiza lucerna. a Size frequency distribution (CL) in male and female shrimps. b Relative growth of the length of the propodus of the major cheliped as a function of carapace length. c Relative growth of the width of the pleuron of the second abdominal segment as a function of carapace width. Linear regression equations obtained after log–log transformation of the data are shown for each sex in Table 1
