A species of sea slug, or nudibranch, makes an exotic addition to the coral reefs off Heron Island on Australia's Great Barrier Reef.

(See stunning photos of nudibranchs from National Geographic magazine.)

Results from a recent survey announced in September 2008 suggest that a large proportion of the animals living on Australia's reefs have yet to be scientifically described, making the true effects of threats to coral ecosystems harder to define.

"Corals face threats ranging from ocean acidification, pollution, and warming to overfishing and starfish outbreaks," said Ian Poiner, of the Australian Institute of Marine Science.

"Only by establishing a baseline of biodiversity and following through with later censuses can people know the impact of those threats and find clues to mitigate them."
