Inferring the mating system in the burrowing shrimp Lepidophthalmus bocourti (Decapoda, Axiidea, Callichiridae) from the social structure and sexual dimorphism

Burrow use and sexual dimorphism as indicators of the mating system in the symbiotic pea crab Austinixa patagoniensis (Rathbun 1918) (Decapoda, Brachyura, Pinnotheridae)

“…Lastly, we conduct a sexual selection analysis to verify if male chelipeds are selected to weaponry and develop one cheliped stronger than other (Hernáez et al, 2021). We predicted that if the major cheliped is sexually selected, the major cheliped would have a steeper scaling value (greater values of slope, β) when compared to the minor cheliped scaling value.…”
