It looks like an aquatic version of Johnny Rotten in his punk heyday after a heavy night on the tiles.

But that spiky green quiff isn't gelled hair - it's growing algae.

And the creature sporting the spectacular coiffure is the Mary River Turtle, one of the most unusual reptiles of its type on the planet.

Ugly/cute!
