Similar to Dahlia anemone, but it grows bigger, the base diameter may reach 20 cm. Furthermore, it lacks the warts on the cylinder wall. The up to 200 stout tentacles are longer and often arranged in multiples of ten. The color variations are pretty much the same, but the Urticina eques is often paler.
It can be found from below the intertidal zone and down to 400 meters. It seems to prefer hard, often rocky, substrate.
This species is common in northern Europe and entire coast of Norway. Registrations from the Pacific Ocean is probably incorrect.
