Velella Velella or “by-the-wind-sailor” washed ashore in the coastal section of Redwood National and State Parks. Examples ranged in color from clear to deep blue. A variety of sizes were noted with most being less than three inches in diameter. This image shows the semi-transparent Velella Velella on the sand with the breaking waves of the Pacific Ocean in the background and a slightly cloudy blue sky above.
