Blue bottles are also known as a Portuguese man-of war, named for its resemblance to a class of warships that was developed in Portugal beginning in the 15th century with the caravel, a light agile sailing ship.
The Purple Sailor Jellyfish (Velella velella) is a free-floating hydrozoan that lives on the surface of the ocean. They are usually deep blue in color with a small ridge on their back. This ridge acts as a sail that propels them over the surface of the sea. Under certain wind conditions, they can end up dying by the thousand on beaches. The velella is carnivorous and feeds on plankton which it catches with tentacles that hang down in the water. This velella was photographed on the Pacific Ocean beach at Rockaway Beach, Oregon, USA.
