About Dolphin
Dolphin Animals - photo wallpapers; Megawallpapers.org:The dolphin is the wood duck of pelagic fishes, so spectacularly colorful that it seems impossible it could have evolved by accident. The back and head are iridescent, glowing neon blue and chartreuse green. The sides and belly are gold, sprinkled with bright blue spots. And, like some other pelagics, the fish has the ability to "light up" with shimmering waves of color across its body, almost as if its skin were embedded with moving lights. In fact, biologists say the fish's color is the result not only of pigment, but of microscopic structures in the skin, which the fish can manipulate to change its color. The color changes could have evolved for spawning selection, or perhaps as a camouflage when approached by predators, as with many bottom creatures. In any case, the spectacular color in life leaves no doubt when a dolphin dies; the skin almost instantly turns an ugly, blotchy gray-silver or dull yellow. Dolphin are found in the Atlantic, Pacific and Indian oceans, anywhere that the water remains at 70 degrees or warmer throughout the winter. In U.S. waters they migrate seasonally, following bait northward along the Atlantic coast to Virginia and beyond in spring, back toward the Keys in winter, but good numbers remain in Florida waters throughout the summer as well.
