Bluewater divers silhouetted against the ocean surface. The safety diver (in the foreground) carries a short stick hanging down from his clip to push away curious sharks. The other diver swims with a collecting bag filled with jars to hold small animals. Another bag is clipped to the down-line below the trapeze. The lines on the right side of the photo are clipped to two other divers (not shown). Image courtesy of Larry Madin.
