Colonies of Cellarinella watersi generally occur in groups of tens to hundreds on continental shelf waters. The Cellarinellids are, all but one, endemic to Antarctica and form great ‘forests’ over parts of the seabed, particularly deeper than 100m. The colonies are thin plates a few mm thick with growth lines obvious representing each years growth. If pieces break off in currents they grow rootlets and re-erect themselves to form new colonies, growing from the fragment. They feed on phytoplankton for about 4/5 months over the summer period when they appear ‘hairy’ underwater from all the tentacles protracting.
