© CatersWarning signs: The animal is commonly known as a variable neon slug due to its incredible colouring of neon green and bright orange
With its otherworldy two heads, you might be forgiven for thinking this two-headed neon slug is an alien lifeform - but it's actually just been discovered right here on earth.
Divers have revealed what they believe to be the first ever two-headed sea slug, and it's a pretty weird-looking creature.
The nudibranch - a soft-bodied, marine gastropod mollusk - was discovered by a diver and a team of film-makers at Kapalai, a sandbar off the coast of Sabah in eastern Malaysian Borneo.
They found that, as well as having two heads, the slug also possesses both female and male sex organs, as all nudibranchs are hermaphrodites.
This particular slug measured around 25mm long, but this species of psychedelic sea slug can grow up to 120mm.
The nudibranch is part of the species
nembrotha kubaryana, but is more commonly known as a variable neon slug due to its incredible colouring of neon green and bright orange which warns predators of their toxicity.
