Beautiful And Rare "Blue Dragon" Washes Ashore In Australia

Looks more like a Pokemon than a real animal, right? But the 'blue dragon" is quite real. It's actually named Glaucus atlanticus and is a small sea slug found in in tropical and temperate waters throughout the world. One recently washed ashore in Queensland, Australia, and the little critter has gone viral.

As popular as this nudibranch is, no one ever mentions that this sea slug (like other sea slugs) is a total badass. Why, you ask? It eats incredibly venomous animals like the Portuguese Man o' War. The sting is agonizingly painful to a human and to most animals, but poses no problem to Glaucus atlanticus, which is immune. After the sea slug has consumed the Portuguese Man o' War it "selects" the most venomous cells for its own use. The slug then incorporates these cells into its own tissues, and uses them as a defense mechanism. It also concentrates the venom, making it far more venomous than the animal it "stole" the cells from.


Came across this odd critter at Broadbeach today. It's a Glaucus Atlanticus.
