A previously unknown species of freshwater sponge has been discovered in Wyndham after it was found attacking water treatment infrastructure. The new species, Corvospongilla moochalabrensis, was discovered in the Moochalabra Dam, where it takes its name, by Water Corporation staff when they were investigating an issue with treatment membranes at the Wyndham Water Treatment plant. The sponge had been damaging the treatment membranes that filter water at the plant so Water Corporation staff sent it off to WA Museum to be examined. After consulting and collaborating with experts in Germany and Italy, WA Museum was able to confirm that the sponge species was indeed new to science. Culture and the Arts Minister David Templeman said the discovery of a new species was very exciting. “It is a great addition to the State Collection and contributes to a greater understanding of Western Australia’s extraordinary biodiversity and to the global understanding of biodiversity in freshwater ecosystems,” he said. “I also hope this new species identification prompts people working in remote waterway environments to collect samples of unusual specimens for identification at the WA Museum.” Water Minister Dave Kelly said it was fascinating to think that the species had been evolving for millions of years and that only now had it been discovered. “It certainly is a sponge with good taste, as Wyndham’s water from Moochalabra Dam was voted the best tasting tap water in WA,” he said. “I’m really pleased that the sponge’s name reflects its Kimberley roots, and I commend all those involved from Water Corporation’s Wyndham and Water Quality teams and the WA Museum.” The discovery is the first time the Corvospongilla genus has ever been found in Australia as freshwater sponges are not commonly found on the continent, with only 27 other types of the fauna recorded in Australia.
