Green balls on Sonora beach are made of marine algae

The “aliens’ eggs” that showed up on a Sonora beach last weekend are nothing more than balls of harmless marine algae, according to local officials.

The eggs term appeared among social media users after no one could say initially what precisely the green balls were, apart from the fact they looked like either avocados, coconuts or balls with a velvet surface.

Thousands of them appeared on the beach at Huatabampito in southern Sonora, located about 350 kilometers south of the state capital, Hermosillo.

The municipal ecology and tourism director explained that expert studies indicated that the balls were made up of marine algae that posed no threat to humans or the environment.

Medarbo Nieblas Márquez said the balls form offshore in rough seas.

A similar phenomenon was seen in Sydney, Australia, in 2014.
