 This shark is caught sporadically, but in large numbers at a time, suggesting they may travel in schools.If so, their photophores may also allow individual sharks in a group to keep sight of and coordinate with their cohorts.Green lanternsharks feed mainly on squid and octopus, and are frequently found with cephalopod eyes and beaks in their stomachs so large that the sharks would have had to distend their jaws considerably to swallow them.
