 Scientists on Thursday released results of a landmark1 study to record the diversity of life in and around Australia’s reefs. The scientists from the Census2 of Marine3 Life have reported finding hundreds of new species of marine life off two islands on the Great Barrier Reef as well as Ningaloo Reef off the western coast of Australia.

Among the most interesting observations are ctenophores, commonly known as comb jellies or pelagic gelatinous invertebrates4, that give off light through bio-luminescence.

Squat5 lobsters6, which are not lobsters at all and are more closely related to hermit7 crabs8.

Pistol shrimp9, which use their large claw to create a sound-pressure wave strong enough to kill small fish.

Star fish and brilliantly colored mollusks. All living together, and some are building hidden habitats on top of the ruins of others.

In surveying the coral on the reefs, researchers also deploy10 new methods that will helpstandardize measurements of coral reefs worldwide. Of the nearly 300 species of soft coral survey, the Census of Marine Life scientists say that up to one half is thought to be new species. Experts say the coral are not reef builders, but they do cover up to 25% of some areas at the study site and provide important habitat for other species. Despite the high distribution of soft coral around the world, it still remains11 one of the most poorly-understood groups.

Doctor Ian Poiner, CEO of one of the organizations that's participating in the expedition, reports that the only way to fully12 understand the implications of the threats posed to coral is to establish a baseline of bio-diversity and follow up with later censuses13. Expeditions to the three sites will be repeated yearly over the course of the next three years in order to continue the census and to study the effects of the climate change and other processes over time.
