Puzzling predators Some animals, such as the deep-sea shrimp, Acanthephyra purpurea, use their bioluminescence to distract or blind predators. The shrimp can actually vomit light into the face of its attacker and then back flip away into the darkness. In this image, which is a composite of flash photos of the animals and a still video frame of the luminescence, a deep-sea shrimp temporarily blinds a viperfish, Chauliodus danae.
