The Threadfin Dragonfish, Echiostoma barbatum, was collected in the Gulf of Mexico between 1,000 and 600 meters depth, 2016. The species has a bioluminescent lure that dangles at the end of a short rod (a barbel) attached to its chin. The massive teeth of this species are used to grip prey items drawn to the lure. It has photophores on its face that produce red light and allow it to see red prey items, like prawns. Red is one of the first colours that drops out of the light spectrum at depths. In deep waters, red turns to black and is invisible to all, except those that can both produce and see red light. The species has been captured as deep as 4200 meters.
