A colony of sea squirts forms a colorful landscape, ample hiding place for an Eastern cleaner-clingfish 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.
Baring rows of serrated teeth, a great white shark is aptly called a killing machine.

Such a symbiotic relationship benefits both the shrimp and the fish.
In the early morning hours of September 1, 1985, oceanographer Robert Ballard and photographer
