This work suggests that in snapping shrimp species that are less cooperative, female - female conflict within the colony has selected for queens that retain weapons at a significant cost to fecundity. (sciencedaily.com)
In queens of snapping shrimp species that are weakly eusocial, the researchers found strong trade - offs between fighting claw mass and egg number. (sciencedaily.com)
To find out, Bornbusch and colleagues determined fighting claw mass and egg number of 353 egg - bearing females from 221 colonies of six eusocial snapping shrimp species in the Caribbean. (sciencedaily.com)
