This beautiful little creature is the glaucus atlanticus, also known as the blue dragon or blue ocean slug. They float upside down on the surface of the water where they are subject to winds and ocean currents and sometimes find themselves washed ashore. In San Diego, we witness the stranding of many pelagic animals, such as the recent not-to-often tuna crab "invasion" of our area beaches and annually, jellyfish.

This rare nudibranch is pelagic and there is some evidence that it occurs in temperate and tropical waters throughout the world's oceans. They live in warm temperate climates in the Southern Pacific, and in Circumtropical and Lusitanian environments off the western Atlantic coast.

This is an El Nino year, strange things can happen and if, and it is a longshot, you see these beautiful animals washed up on shore on a San Diego beach, do not handle them! They are highly toxic themselves, and also able to swallow the venomous nematocysts from the much larger Portuguese man o' war and store them, increasing their toxicity. Picking up a tiny blue dragon can result in a painful and even deadly sting with symptoms similar to those caused by the Portuguese man o' war.
