Two-headed prawn shocks Qld aquarium staff

Two heads are better than one - except when you're eating a prawn.

Drawing comparisons to the infamous three-eyed fish in The Simpsons, a two-headed prawn has been discovered by shocked staff members at Townsville's Reef HQ Great Barrier Reef Aquarium.

Aquarist Laura Colton says she originally assumed the soon-to-be fish food was two prawns stuck together.

Hundreds of people have shared the photo on social media.

Concerns that it may have been a mutated, nuclear powered superprawn were soon allayed by Professor Dean Jerry of James Cook University.

He explained it was far more likely to be a rare natural development such as Siamese twins.

Those braving the winter winds for Christmas in July parties may be thinking twice about ordering a prawn cocktail.
