GEORGE TOWN: Raw animal waste pouring into the sea from mainland Valdor will potentially cause destructive jellyfish blooms that create “dead zones” in the sea around Penang, a marine biologist says. Jellyfish can increase and gather in such large numbers that they crowd out all other sea life, said Datuk Prof Dr Aileen Tan. “This will deplete the oxygen until fish cannot thrive, but jellyfish need very little oxygen,” she said. Marine life: A pail containing an Australian spotted jellyfish and box jellyfish of the Morbakka genus caught in the sea off Batu Ferringhi. Researchers comb the sea during neap tides with special netting and trap hundreds of jellyfish each time, including the deadly box jellyfish.
