Unidentified Floating Objects have Washed ashore on Dee Why Beach
The UFOs or unidentified floating objects have washed up on the Dee Why beach in north of Sydney and it is difficult for locals to find out what they may be.
The beach has been transformed into a very strange landscape as the whole place is covered in green alien balls.
"They're actually a really unusual growth form of seaweed, because seaweeds mostly grow on the rocks but occasionally they get knocked off and rolled around in the ocean forming these beautiful little balls", said Professor
Alistair Poore from the School of Biological, Earth and Environmental Sciences at the University of NSW.
Adding to it, the Professor said that it is quite a strange phenomenon and it is only visible a few times around the world.
According to University of New South Wales in Sydney, the balls could be an unusual kind of living green algae. In Japan, these living organisms are identified as 'Marumo' and Cladophora ball or Lake Ball in English, and frequently found in freshwater lakes in the Northern Hemisphere. Experts say that they have been washed ashore by warmer weather and rough waves.
Thousands of these balls of about six centimeters emerged on the beach overnight. Surfers and beachgoers were shocked by the number of green, sponge-like spheres on the beach.
Jenny Zhang, local resident, said that about three days ago there were a few egg-shaped balls on the beach but now they have become much larger and can be seen everywhere on the beach.
According to scientists, the sponge-like spheres are seaweed that group together in the form of an egg to guard themselves from predators. It is not known that why the algae forms into balls but it is assumed that ball-shape helps guard the algae from hungry fish and another that it may help them roll back into the water and keep them away from drying out when they wash ashore.
