Blue blubber jellyfish

'Wallpaper of blue blubber jellyfish' wash up on Queensland beach

There was no sand in sight at Deception Bay at the weekend when thousands of jellyfish stranded themselves, in what is known as a bloom.

Marine biologist Dr Lisa-Ann Gershwin, who specialises in jellyfish, said the bloom was one of the biggest she had seen in her 25 years of research.

"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.

"We see jellyfish bloom, but not like this, this is jaw dropping."

Dr Gershwin described the sight as "a wallpaper of jellyfish".
