Surfers and early morning walkers were stunned to find thousands of 'alien eggs' on a Sydney beach this weekend.

Locals in Dee Why, on the city's North Shore, reported seeing a large number of the strange objects which had washed ashore overnight.

But rather than the green spheres being something from another planet, scientists explained they were a type of sponge-like seaweed that forms egg shapes possibly to protect themselves from predators.

Associate Professor Alistair Poore from the School of Biological, Earth and Environmental Sciences at the University of NSW said the balls were probably a rare type of living green algae, which has only been seen a handful of times around the world.

'I’ve seen similar things - sometimes dead sea grass can roll around and form balls like underwater tumbleweeds but that’s made of dead material and these look to be living,' he told The Manly Daily.
