A POSSIBLE new species of seahorse is among creatures gathered during a scientific expedition down into the extreme depths of the Great Barrier Reef.
Researchers gathered a pygmy seahorse, a tiny 5mm long fish that was found living on a piece of coral at a depth of about 100m, about 200km off Cairns.
The major ocean research expedition, which left Cairns more than a week ago, used advanced underwater technology such as a robotic remote operated vehicle to explore the "twilight zone" 30m to 150m below the sea’s surface. The seahorse will be sent to an expert in Canada to determine if it is a new species.
The expedition was a joint project between James Cook University, University of Queensland, University of Sydney and the Museum of Tropical Queensland.
