During spring and summer in the Salish Sea, we often encounter thousands of these little floating hydroids. Commonly known as \u2018by-the-wind sailor\u2019, \u2018sea raft\u2019 or by their scientific name, \u2018Velella velella\u2019, each little \u2018boat\u2019 is actually thousands of individual polyps that are the preliminary stage of a small jellyfish. Each raft has a rigid \u2018sail\u2019 structure that acts as an airfoil that tends to sail downwind at a small angle \u2013 no tacking has been invented yet, so bad navigation is frequent. Sometimes things really go wrong and they all end up on shore, stranded in rotting beach piles that dogs love to roll in. As I mentioned, each of these, boat and sail, is a carnivorous colony of hydroids with stinging tentacles that hang down beneath the raft. These are used to sting passing plankton that the tentacles then pass over to the waiting central mouth that distributes food to polyps by small connecting tubes.<\/p>\n

 <\/p>\n

While each \u2018raft\u2019 is somewhat like a coral reef, these colonies of polyps are the first phase of a two-part life. There are different types of polyps in each \u2018boat\u2019, just like bee colonies. Some are feeders with reproductive parts, some are protective. The reproducers become thousands of tiny jellyfish over several weeks. For some reason, these young don\u2019t seem to get captured by the hanging deathtraps beneath the raft. Like a coral colony, the polyps need a water environment but have figured out how to do that by simply living on the surface while clinging to bottom of a raft of their own making. The sail helps distribute them ocean-wide so they don\u2019t need a shallow reef to cling to. I guess you might say they take their reef with them. Next time you see these floating by, gently pick one up and carefully view the underside where the real action is.<\/p>\n
