Tube Anemones [Cerianthidae]

Description

Cerianthidae, commonly known as tube anemones, are a family of ceriantharians characterized by living in soft sediment environments from which they project. They are notable for their long, tube-shaped bodies encased in a secreted tube made of a fibrous proteinaceous material, distinct from the calcium carbonate tubes created by some polychaete worms. These anemones have two sets of tentacles, with the outer set being long and used for feeding, and the inner set shorter, surrounding the mouth. Tube anemones are often colorful, displaying vibrant patterns and hues. They feed on small organisms, such as plankton, which are captured with the stinging cells on their tentacles. Cerianthidae differ from other anemone families primarily in their habitat and physical form, particularly the presence of the tube which provides protection from predators and environmental conditions.
