The mottled anemone (Urticina crassicornis; formerly, Tealia crassicornis), also known as painted anemone or Christmas anemone, is a large and common intertidal and subtidal sea anemone. Its habitat includes a large portion of the coastal areas of the northern hemisphere, mainly polar regions, and it lives a solitary life for up to 80 years of age. Mottled anemones are similar to Dahlia anemones (U. felina) and both are commonly referred to as northern red anemones.
