10 cm

The Tube Anemone is found in New South Wales.

Habitat

Tube Anemones live in coastal waters, estuaries and soft seabeds.

Other behaviours and adaptations

The tentacles of the Tube Anemone reach out of the tube and capture small animals using stinging cells (nematocysts). The main body of the animal is not attached to the tube and can retract rapidly when threatened. Divers often see the anemone disappearing into the sediment as they approach for a closer look.
