Show I . Tropical Fish Submarine color photography has given additional evidence for the theory the-ory that the gayly colored fishes of troplcnl reefs wear their gay colors so that they may more easily fade Into, their environment. They escape larger, fish which prey upon them while at the same time becoming hnrd to be seen by the littler fish upon which they In turn feed. Photographs taken near the sea bottom in these shallow waters have shown the natural background back-ground of corals, sponges, sea-anemones and other marine growths to be brilliantly colored. The gaudy fish merely conform to their background, and their gay colors are another instance in-stance of natural camouflage. |
