New Species Discovered On Aussie Reefs

Did you read the article on The Straits Times yesterday 20 Sep 08? Marine scientists said that they have discovered hundreds of new animal species on Ausse reefs (Great Barrier Reef and Ningaloo Reef). This is a wonderful achievement and I was thrilled with the pictures taken. When I was at Ninglaoo Reef in June 2008, this discovery was not known yet. Anway, I hope that when I next visit Ningaloo Reef, I have the opportunity to view some of the new species :)

I like this twisted nudibranch, (Chromodoris Elizabethina), on the reef face off Heron Island most. It is very bright and colourful.

About half of the 300 soft corals found are thought to be new discoveries, although they will only be given names and classified formally once the scientists have compared them against existing species. Unlike their hard-bodied cousins, soft corals do not build reefs but are nevertheless considered vital for the marine environment. These colourful animals can dominate some regions of the sea, covering up to 25 per cent of the ocean floor.

The latest discovery is a result of a four-year project centred on the extensive coral reefs of western and north-western Australia and is part of a larger effort to take a census of all marine life in the world, due to be finished in 2010. When complete, the census will be used as a "baseline" to try to quantify the rate at which species are becoming extinct in the marine environment. Coral reefs are considered to be the rainforests of the sea because of their rich biodiversity. It is estimated that something between one million and nine million species of marine creatures live in and around coral reefs, but scientists have little idea of the precise numbers.

Here is a dendronepthya soft coral

and a ctenophore or comb jellyfish

Hi Yi Xi,

Nice blog you have been updating to date.

Don't let this 'die' off.

Continue this good work and remember to use your voice to spread the voices of the reefs to your friends. =)
