Fluorescent Coral Communication

Justin Marshall of the University of Queensland studies how animals—from parakeets to reef fish—use color for communication. These fluorescent corals are of particular interest as part of the reef fish environment, an environment Marshall is studying in the Great Barrier Reef.  He studies how fish and coral communicate and signal with colors beyond the light spectrum visible to humans, a study that is shedding light into how reefs are being affected by global warming.
