77 Harold E. Edgerton and Jacques-Yves Cousteau Deep-diving Cameras Record Teeming Life Far Below Surface To Cousteau, all past efforts to photograph the sea's inhabitants re semble those of a balloonist lowering a camera through the earth's cloud cover and shooting pictures at random. Such a census taker would be lucky to de velop, on one print out of 5,000, the image of some passing bird or animal. The ocean's habitable area is many times that of man's estate; yet the bathyscaphe's first, tentative explora tions have revealed even at great depths a startling richness of marine life, from a thick, unceasing "soup" of micro organisms to groups of sharks, crabs, squids, and shrimps. The thin, wirelike creature above has never been identified; apparently it swims too fast to be netted. Odd streamered siphonophore at right, pos ing for its first picture undersea, is a cluster of dozens of marine animals. Six-foot shark (below) with white protruding eyes is first ever photo graphed below 2,000 feet. In complete darkness at such depths, fish apparently use their eyes only to pick up the phosphorescent glow of their prey.
