- Avoidance of Trawl: A behavior in which fish move out of the way of an incoming net, perhaps through bioluminescent signalling.
- Bioluminescence: Light produced by a living organism.
- Deep water fish: Fish who live more than 500m below the ocean surface in the Mesopelagic, Epipelagic, and Bathypelagic zones.
