00 Drawn by Zhenya Gay after Carl Chun THESE DEEP-SEA DWELLERS KEEP THEIR HEAD AND TAIL LIGHTS GLOWING ALWAYS No daylight penetrates half a mile below the ocean's surface to the haunts of the luminescent squid. Light organs, sprinkled over the body orarranged inrows around the eyes and along the tentacles, probably lure tiny victims within striking distance. Lenses, reflectors, and color screens enable some species toproject beams of colored lights. The drawings are about natural size.
