Bright & Beautiful Bioluminescence

bi·o·lu·mi·nes·cence Noun /ˌbīōˌlo͞oməˈnesəns/
1. The biochemical emission of light by living organisms.

Stauroteuthis feeds on small crustaceans that are attracted to  light. Once the unsuspecting critter is close, the octopus grabs it and  traps it within a mucus web produced by glands on its arms. In the first study (pdf) to document Stauroteuthis'  bioluminescence, Duke University's Sonke Johnsen and colleagues  observed that, when disturbed, the octopus splayed out its arms and  exposed all its flashing photophores in an attempt to scare off unwanted  guests.
