A colony of sea squirts forms a colorful landscape, ample hiding place for an Eastern cleaner-clingfish (Cochleoceps orientalis) in the Tasman Sea off the coast of Australia. The tiny fish, which cleans parasites from the bodies of larger fish, fights strong currents by anchoring itself with a sucker disc on its abdomen.
