A ceriantharian, also known as tube-dwelling anemone, filmed during Dive 5. In contrast to sea anemones, ceriantharians have two rings of tentacles with different tentacle lengths. The outer and longer ring of tentacles is used to capture food particles from the water column, while the inner and shorter ring of tentacles is used to move captured food particles towards the mouth.
