Land slugs drew the short straw when it came to looks. Meanwhile, their sea-dwelling counterparts come in all shapes and colours, and the Phyllodesmium poindimiei is just one psychedelic example.

Also known as Spun of Light, this otherworldly friend is an aeolid nudibranch Gastropod belonging to the family Facelinidae that feeds on a type of coral called Alcyonacea. To non-slug specialists, it may as well be an adorable alien - but rest assured, the Phyllodesmium poindimiei isn’t a space-faring slug but a coral-dwelling creature found near the coasts of Australia, Hawaii and the Indo-Pacific region. The long, pink outgrowths on its back are called cerata - they help the sea slug defend itself and carry out important metabolic processes.
