Cloning is Bad! :: essays research papers
&65279The coela hoboth is an amazing creature full of mystery and raise discoveries. It was once thoughtto be extinct for more than360 milllion years agone until one was caught in1938.Its scientific name is Latimeria chalumnae .An adult coelacanth can grow at least to 180 cm in space and weigh 98 kg and each fish has a feature pattern of pinkish white blotches that enables scientists to separate one individual from an other.The coelacanth has several very recognizable anatomical features.The skull is in two part with an intra cranial joint which lets it go an up and down movement betwixt them. A strong pair of muscles beneath the skull-base lowers the front half of the skull, big(a) the coelacanth a powerful bite .The eyes and olfactory organs are in the front part of the skull, and tiny brain and privileged ear are in the rear.In the middle of the snout is a Brobdingnagian pit filled with a jelly- worry sac that opens to the outside through tether pores.This sac is called the rostral organ .It may be used to detect asthenic electric currents and help the coelacanth to find hidden prey.The finsCoelacanths belong to a group of bony lobe-finned fishes and have 8 fins (2 dorsals, 2 pectorals, 2 pelvics, 1 anal and 1 caudal). The first dorsal fin of the coelacanth is ofttimes like that of other fishes and can be folded down or erected. The other fins have a well-developed, muscular, limb-like basal lobe projecting from the body wall, and a flush of unbranched rays like a fan attached to the outer expiry of the base. The fleshy scale -covered lobe can be bent or rotated so that each fin can work like a paddle or sculling oar. The tailhas three divisions a characteristic small projecting middle lobe between the longer upper and lower lobes of the fin.The skeletonMost of the skeleton is made of cartilage. In place of the vertebral column, a large notochord extends from the skull to the tip of the caudal fin. The notochord is a thick-walled cartilaginous electron tube filled with oil-like fluid which is under slight pressure it is tough and stretch and does the job of a backbone, since no complete vertebrae are developed nearly it.The scalesThe body is covered with hard scales with small toothy-like growths called denticles on the outer move up which protect the coelacanth from the rocks and predators.The swimbladder
