Dolphin

The dolphin is the wood duck of pelagic fishes, so spectacularly colorful that it seems impossible is 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 smimmering waves of color accros its body, almost as if its skin were embedded with moving lights.
In fact, biologists say 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. th 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 turn an ugly, blotchy gray-silver or dull-yellow.
Dolphin are found in the Atlantic, Pasific and Indian oceans, anywhere that the water remains at the 70 degrees or warmer throughout the winter. In U.S. water 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 water throughtout the summer as well.
The dolphin in unique among pelagic fishes in that the mature males have a distinctly different shape than the females; the forehead of an adult "bull" in high and blunt, while the "cow" has a more typical streamlined forehead. ( the male look just like famales until they approach adulthood.) There are no reports of the male using this head as a battering ram in mating battles, but it's pretty clearly a secondary sexual characteristic.
Dolphin reportedly can reach speeds up 50 mph, and sometimes run down flyingfish in the air, though more commonly they race along just under the sunface, watching a flyer and eating it the second it touches down. The also eat lots of squid, small bonito and other pelagic bait.

Lumba-lumbaLumba-lumba adalah bebek kayu Ikan Pelagis, begitu spektakuler warna-warni bahwa hal itu sepertinya mustahil adalah bisa telah berevolusi oleh kecelakaan. Punggung dan kepala yang berwarna-warni, bercahaya neon biru dan chartreuse hijau. Sisi dan perut adalah emas, ditaburi dengan bintik-bintik biru cerah, dan, seperti beberapa pelagics lain, ikan memiliki kemampuan untuk "cahaya" dengan gelombang smimmering warna accros tubuhnya, hampir seolah-olah kulit tertanam dengan bergerak lampu.Bahkan, ahli biologi mengatakan ikan warna adalah hasil tidak hanya pigmen, tetapi struktur mikroskopis di kulit yang ikan dapat memanipulasi untuk mengubah warnanya. perubahan warna th bisa telah berevolusi untuk pemijahan pilihan, atau mungkin sebagai kamuflase ketika didekati oleh predator, dengan banyak makhluk bawah. Dalam setiap kasus, spektakuler warna daun hidup tidak diragukan lagi ketika lumba-lumba meninggal; kulit hampir seketika belok jelek, jerawat abu-abu-perak atau membosankan-kuning.Lumba-lumba ditemukan di Atlantic, diAmerika dan India lautan, di mana saja yang air tetap pada 70 derajat atau lebih hangat sepanjang musim dingin. Di US air mereka bermigrasi secara musiman, menyusul umpan ke utara sepanjang pesisir Atlantik ke Virginia dan seterusnya di musim semi, kembali menuju kunci di musim dingin, tetapi nomor bagus tetap di Florida air throughtout musim panas juga.The dolphin in unique among pelagic fishes in that the mature males have a distinctly different shape than the females; the forehead of an adult "bull" in high and blunt, while the "cow" has a more typical streamlined forehead.
