Morphology
The specific name ‘coccinea’ means ‘scarlet’ and refers to the anemone's distinctive often reddish and orange-striped coloration both on the column and on its up to 80 tentacles. The anemone can grow to a size of 6 cm in diameter, but the anemone has a very flat appearance when retracted.
Ecology
This species attaches itself to rocks and shells, with the most common substrate in northern Europe being the shell of the horse mussel Modiolus modiolus, where, as a suspension feeder it consumes planktonic material. When there is an attack from one of its predators, such as a starfish, or an individual of the nudibranch species Aeolidia papillosa or Eubranchus exiguus, it can release the grip of its disc and float away. If it is successful in escaping, it will soon after attach to a new substrate.[1]
