One Kind Of Octopus Lights Up Like A Christmas Tree
Bioluminescence is a characteristic of a few marine animals, in which they can light themselves up, seemingly at will. They contain particles called photophores, which emit light, almost like when the lights on a Christmas tree are turned on and off.
The bioluminescent octopus has been seen off the coast of Maine, in the northeastern United States. Scientists believe that by lighting up the underside of its tentacles, it can fool prey so that they swim straight into its mouth.
