Anemones: More information

Description: Shaped overall like shallow bowls with ultra-thick bottoms attached to the substrate, sea anemones may look more like flowers than like animals—especially the ones that are green.  Pointed “petals” around the top rim are stinger-armed tentacles that frame the central disc, the mouth of the animal.  The floor of the central disc is smooth with a doughnut-shaped lump in the middle, while the outside of the body, below the tentacles, is usually a darker green and rough, and is often flecked with bits of shell.  Many of the intertidal sea anemones you are likely to see in Oregon are olive to bright green (some species have splashes of other colors).  Depending on species, age, and environment, some of our tidepool sea anemones can grow up to 10” across (about the size of a dinner plate!).
