Male mating tactics in the horseshoe crab, Limulus polyphemus
Article Abstract:
Male horseshoe crabs mating behavior is affected by condition dependent factors. Males returning to the beach in an unattached position are darker in color and are more likely to have their eyes and prosomas encrusted with epibionts than males arriving attached to females. Attached males are either younger than the unattached crabs or have moulted recently. When attached males were forcibly detached and released in the sea, they were more likely to return to their partners than originally unattached crabs.

Female behaviour, sexual competition and mate guarding in the blue crab, Callinectes sapidus
Article Abstract:
A study was conducted to study sexual competition and mate guarding in the blue crab, Callinectes sapidus. Data were evaluated and analyzed for normality using the Kolmogorov-Smirnov test while the descriptions of courtship were utilized to define the repertoire of behaviors. Results showed that the changes in female behavior are consistent with the female's need to avoid the costs of guarding. They also indicated that female blue crabs influence how pre-copulatory mate guarding happens.

Why do male crab spiders drink nectar?
Article Abstract:
The selective advantage of increased longevity for male reproductive success may lead to the evolution of nectar feeding in crab spiders. The use of nectar as an energy source is suggested. Study on Misumenoides formosipes show that they were more susceptible to dehydration than females because of their low mass and large surface-to-volume ratio. Fluid that males lost through evaporation is replaced by drinking nectar, but dew and rainwater were more important sources of fluid.
