Sciartober Day 18: For the prompt: aquatic, some simple shapes and a quick rendering. These are by-the-wind sailors or Velellas, a jelly relative. Each individual is a hydrozoan colony. Most people know them from the ones that wash up on beaches, looking mostly clear, with a bit of brilliant blue. Kuratake brushpen and Sharpie fineline marker on Canson XL watercolor.
