Most sea anemones spend their life attached to a surface, although many can detach themselves if conditions become unfavourable. New Zealand’s largest sea anemone, the wandering anemone (Phlyctenactis tuberculosa), is an exception. It has opted for a more mobile existence drifting among dense seaweed. Its bladder-like extensions keep it buoyant. This one, attached to a brown seaweed, is in its contracted state. Māori call this animal hūmenga.
