Sea Slug Census, a different kind of survey

The Blue Dragon is a master of disguise, using its blue colours to blend in with the sea and sky on it’s quest to consume the stings of blue bottles.

When it does, it holds onto the poison for protection, distributing it to the tips of its beautiful ‘wings’. While they don’t always sting, Blue Dragons can deliver a punch similar to that of a bluebottle.

Unlike other nudibranchs, the Blue Dragon swallows a bubble to so it can float on the surface of the sea and can end up on our beaches during prevailing onshore winds.

It’s one of the amazing creatures we’re chasing during the annual Sea Slug Census in April, a collaboration between the Atlas of Life and Southern Cross University.

Others include the slow moving sea hares who graze on algae covered rocks like cows in a paddock, and bubble shell snails who can’t hide inside their shell and rely on camouflage and speed to escape predators.
