The organ has been hypothesized to serve the obvious purpose of luring prey in dark, deep-sea environments, but also serves to call males' attention to the females to facilitate mating. Thus, males never mature without attaching to a female, and die if they cannot find one. Males would be expected to shrink to reduce metabolic costs in resource-poor environments and would develop highly specialized female-finding abilities. Anderson, M. Eric, and Leslie, Robin W. 2001. It is battled in one of the underground, side-scrolling areas of the Dungeon, with a bumpy ground that Link must use the Roc's Feather to traverse.

The source of luminescence is symbiotic bacteria that dwell in and around the esca, enclosed in a cup-shaped reflector containing crystals, probably consisting of guanine.
