Description
Characterized by their large tubular bodies, deeply embedded in holes and sediments with the aid of their mucus.

Fun Fact
Despite its name, the tube-dwelling anemone (order: Ceriantharia) is not a true anemone (order: Actiniaria)! Unlike true anemones, tube-dwelling anemones do not have a pedal disc that can attach to surfaces or allows it to move from one point to another.
