Velella are stranded by the thousands at Pacific Beach, Washington in early spring. The Velella are washed into shore on warm spring tides. Their deep blue color is bleached away by the sun as they slowly decompose. Velella are a relative of the Portuguese man o’ war and are actually a community of organisms that function as one. They are also known as sea raft, by-the-wind sailors, purple sail, or little sail.

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.
