Melbourne (Staff Report): A beach in Australia's Brisbane was taken over by an army of jellyfish , becoming cynosure for passers-by.

It happened at Deception Bay, Brisbane where an army of blue blubber jellyfish (Catostylus mosaicus) were spotted on the beach by a number of people.

The animals were not actually taking over the beach but appeared as a result of a natural phenomenon known as a bloom.

Dr Lisa-Ann Gershwin, a marine biologist, said, ‘Jellyfish bloom is part of their lifecycle and if the winds blow just right and if the water level falls with the tide, then they get stranded.’

The bloom usually lasts a week before the tide comes in and takes the animals back into the water, said the marine biologist.
