SpeciesEdit
Anyone know what these are? The article says "tube worm," the categories say "plant," and my own experience coupled with their body structure says they're a polyp of some Cnidarian. They have leaf-like structures, but no plant is fully-aquatic that I'm aware of (things like kelp are classified as Protists, not Plants). Any ideas?
