Anemonefish live in the tenticles of some sea anemones. The anemone’s stinging cells protect the fish from predators, but the anemonefish don’t get stung because they are covered in a protective slime!

Meat-eating flowers?

Named after flowers found on land, sea anemones are animals with a soft tube shaped body and a mouth surrounded by tentacles. These tentacles are packed with the same stinging cells as jellyfish and are used to catch their food. The Cockburn Sound anemone is found from Fremantle down to the Cockburn Sound inlet and it’s dangerous to humans- the densely packed stinging cells located in the spots on the tentacles causes burn-like stings and scars that can take months to heal.

Dinner time

Sea anemones eat small fish and other animals. Once captured, the food is passed by the tentacles into the sea anemone’s mouth. Any waste comes back out through their mouth, as sea anemones have one body opening – not two!

Body Base

Sea anemones may have a pointed base, or foot, for burying in the sand or a sucker like base to attach to rocks.

On the move

Sea anemones glide through the sand by moving the base of their body. Some sea anemones use their tentacles to walk or swim, while others float by folding their body base and trapping bubbles of air.

Its war!

Sea anemones compete for space and food. If an anemone grows too close to another, they will inflate their tentacles and release poison darts from their stinging cells.
