Abstract Bioluminescence (light production) and fluorescence (re-emission of absorbed
radiation as light) are found in an unaccountably diverse array of marine organisms, where
their functions are largely unknown. Here we report a deep-sea siphonophore that twitches
glowing lures to attract fish. This is rare evidence of bioluminescence used for prey attraction
among nonvisual marine organisms. The lures also contain red fluorescent material that
shifts the wavelength of emitted light. The existence of a red-luminescent invertebrate ...
