The mysterious blue sphere filled the coast of Australia

Hundreds of moss-green strange strange objects have drifted to Australia's beaches these days. People here call strange objects 'alien eggs', while scientists consider it to be an algae.

Over the past days, hundreds of unknown, blue and soft spherical objects have drifted into Dee Why beach, making local people always wonder whether this is a strange creature egg or just It is simply a Japanese algae.

The spheres are green moss, velvet-like surface

Dee Why Beach Rescue Patrol member Rae-Maree Hutton said she witnessed these strange objects as she walked on the beach early in the morning.

'I did not dare touch them with my hands because I did not know if they were injecting, but I tried to lightly touch my toes, finding them quite soft, like a sponge,' Hutton said.

Jenny Zhang - a Narraweena resident - said she walked on this beach every day but had never seen anything similar.

Hundreds of "strange eggs" drifted off the coast of Australia

'Three days ago, the Australian beach appeared a few small eggs, but today, the objects washed up on the beach more and more and they were bigger than before. I tried to go online to search for information about them but found nothing. They are similar to moss balls in Japan but not made of moss, possibly seaweed , 'Ms. Zhang said.

Associate Professor Alistair Poore - Department of Biology, Earth and Environmental Science at the University of New South Wales - said it is likely that the spheres are still green algae.

'They are quite interesting. I have seen the same thing, the sometimes dead seaweed rolled into a shape like a ball under water. However, those spheres are made of dead plants, but here, it seems these creatures are alive. '

Researcher Alistair thinks it could be a form of aegagropilious - a type of moss bridge found in Japan, where living algae clump together to form a sphere (not containing stones).

Expert Alan Millar from the Royal Australian Botanic Garden Center said it is possible that spheres of seaweed are affected by the weather plus the impact of strong waves.
