Justin Marshall (neuroscientist)

Nicholas Justin Marshall FAA (born 1962) is a British-Australian neuroscientist-ecologist whose research focuses on decoding how animals use colour to communicate.

Marshall attended high school in Cambridge and studied a Bachelor of Science in zoology, graduating with 1st class honors from the University of Sussex, UK in 1985.

[4] He showed that mantis shrimp and cuttlefish can reflect and detect circular polarised light,[5][6] which is closely linked to covert communication.

He has made discoveries in colour vision in several other animal groups, such as marine and freshwater fish, cephalopods, birds, lizards and crabs.

His research student Wen-Sung Chung was the first person in the world[9] to see a giant squid in its natural habitat in July 2012, via a video cameras set up by Japanese broadcaster NHK.
