Photostomias guernei is a species of barbeled dragonfish in the genus Photostomias. P. guernei is a scaleless, ray-finned fish found in deep oceans. The species has been documented in the Atlantic and Pacific oceans, and fully-grown members of the species can reach a maximum length of ~16 centimeters. It is defined by its deep-sea lifestyle and predatory existence. This fish possesses bioluminescent organs used to draw in prey and attract mates, exhibiting strong sexual dimorphism in morphology.
