Bluebottle

Physalia utriculus

A Physalia utriculus, also known as the Pacific man-of-war or bluebottle – its shade of blue is one of the most beautiful things I have ever witnessed. Every summer bluebottles sting about 40,000 Australian beachgoers, but their design and colour is truly art in nature.
