TABLE 2 .
Overview of genomic features of the symbionts of three anglerfish specimens (two C. couesii and one M. johnsonii) compared to the genomes of symbionts from two flashlight fish (Anomalops katoptron and Photoblepharon palpebratus), two free-living, nonsymbiotic relatives, and a facultative symbiont of Euprymna scolopesa
