PNAS Cover for Euprymna paper

Cover information from PNAS:

Pictured is an adult Hawaiian bobtail squid, Euprymna scolopes, which has distinct symbiotic organs. Mahdi Belcaid et al. analyzed the genome of E. scolopes and found that two of the cephalopod's symbiotic organs—a light organ to protect it from predation and an accessory nidamental gland found only in females—evolved independently of each other. The findings suggest that multiple symbiotic organs can evolve through different pathways within a single host. See the article by Belcaid et al. on pages 3030–3035.
