This is the velella (Velella Velella), a small free floating hydrozoan. It's currently the only known species in the genus. They're also known as sea-rafts or by-the-wind-sailors, for the obvious reason that it uses the the "sail" you can see in this image for locomotion. Because of this, they are often found washed up on beaches.
Red Sea #Anemonefish: The louder the fish and anemone, the more I'm attracted to them. Fish have been in my drawing (& coloring) repertoire since I was about 5. Which might explain why I like the bright colors found in tropical seas,
