Growing as tall as 30 cm (1 ft), the plumose anemone (Metridium senile) resembles an overzealous shag carpet coming out of a mushroom stem. Fragments of this stem can grow into new anemones.
Though it is most commonly found in either orange or white, it can also be yellow, red, brown, or gray. They typically live on pier pilings or shipwrecks, extending out into the current to allow their tentacles to capture prey. Large specimens may have as many as 1000 tentacles on a single head.
