The Portuguese man-of-war is not a jellyfish, but is related to them. They are quite amazing, both in form and function. It is made up of a colony of genetically-identical creatures that take different forms to make up the “organs” of the colony. Photographer Aaron Ansarov has been photographing Portugese man-of-wars for two years to capture their ethereal beauty. You can read more about the animals and see more of Ansarov's pictures at National Geographic. -via Nag on the Lake
