Don't worry, the Khaleesi isn't nearby and you're not looking at a real life Pokemon either. The creature in the video is called a blue dragon, but it actually comes from the slug family. Glaucus Atlanticus, also known as the sea swallow or blue angel, is a rare little creature that occasionally washed up on to Australian shores, which is how Lucinda Fry found it in Broadbeach, Queensland.

The blue dragon is actually tiny – it grows to about 3 cm in length – but that doesn't make it look any less stunning. The creature floats about on the surface of the ocean, thanks to a gas-filled sac in its stomach, so the beautiful blue portion is actually its underside.

The blue underside blends in with the surface water allowing it to float along the ocean's surface, until it runs into a creature like the dangerous Portuguese Man O'War. Those jellyfish-like creatures are incredibly venomous but Glaucus Atlanticus is able to not only feed on them but also store the venom in its own tissues. As a result, humans handling a blue dragon could easily end up getting a powerful sting.

The animals mostly live in the open ocean, which is why they aren't often seen by humans on the coasts. They can occasionally wash up on beaches, however, and not only down under. The animals have even been found in the Bay of Bengal and have turned up on the shores of Andhra Pradesh and Tamil Nadu. Aspiring Khaleesis, however, should beware that trying to pick them up could result in a painful sting.
