  • Abstract. The sponge-dwelling shrimp Synalpheusregalis and several congeners exhibit monogynous, eusocial colony structures, and field data suggest that these social species may have a competitive advantage in crowded environments. We explored mechanisms of colony defense, a likely contributor to such a social advantage, by measuring responses of resident shrimp to conspecific and heterospecific intruders in experimental nests. To test for behavioral differentiation among classes of individuals… CONTINUE READING
