Nine species of midwater cephalopods, fish, and shrimp, examined ina shipboard aquarium, adjusted the intensity oftheir luminescence to match the intensity of the overhead light. Most animals tested could regulate this ventral countershading luminescence in response to a wide range of light inten sities. A black anglerfish, Cryptopsaras couesi, also produced a faint later glow, indicating that bioluminescence may be important in lateral countershading in some species. Our observations indi cate that ventral countershading is effective to depths of 750-775 m during the day off Hawaii. We suggest that the concealment strategy of ventral bioluminescent countershading is limited to depths greater than 350-400 m, largely because of the high visual acuity of predators and the high cost of producing countershading luminescence at lesser depths. 14 pp., 4 figs, gr. 8.
