Organisms Physiology Essay

Organism Physiology is the method in which many diverse vitality organisms atomic number 18 considered to guide developed from earlier forms during the history of the earth that nookie be defined as Evolution. Several organisms ache evolved as a result of environmental changes within their habitats. Ex ample is a diagram of a giant star and details about how the whale has evolved physiologically and has become qualified to fit the environment. Kingdom Animalia, Phylum Cordata, Class Mammalia, Order Cetacea, Sub- battle array Odontoceti, Family Delphinidae, Genus Orcinus, Species Orca. Whales occupy all oceans and study seas, even some ar in larger river systems. They are real large sentient beings. They displace grow up to 100 ft. or more than in length. They can weigh up to 200 tons or more. Whales constitute in families called pods. These pods falsify in numbers and consist of family members and family friends.Whales live in these families their whole life. Group li ving is safer when other whales or sharks attack. It besides makes it easier to find forage. Whales are always migrating. They travel to find diet, breed and give way newborn. Whales do not have eyelids. They rely on thick saponaceous tears to protect their eyes. Whales hear from little holes behind their eyes. They talk to from each one other by making high pitched weightys comparable whistles, clicks, squeaks, rattles, and groans. Whales know all oceans and the seven seas some also inhabit larger river systems. They are extremely social organism and use communication for the function of hunting, defense, and reproduction. In general a dolphins live pods of up to a dozen individuals. mahimahi pods can emerge temporally forming a super pod the uphill pods may exceed thousands of dolphins. Attachments in pods are not set tack is regular. On the other hand, whales can generate great social bonds they leave behind re of import with wounded or individuals in poor health, e ven assisting other whales to breathe by bringing them to the surface if required. Whales arewidely classed as predators, but their food ranges from microscopic plankton to very large fish.Males are called bulls females, cows. The young are called calves. Because of their environment, whales are conscious breathers they decide when to breathe. All mammals sleep, including whales, but they cannot afford to fall into an unconscious(p) state for too long, since they need to be conscious in order to breathe. Whales also communicate with each other using lyrical sounds. creation so large and powerful these sounds are also extremely audible depending on the species. The most dangerous predator for the whale is mankind and temper change. Man slaughters whales for their meat, fat, and for being in the same location where they fish. There studies at this time being done to evaluate the influence of pollution in the water and the effects on whales. Whales are threatened by mode change an d global warming. As the Antartic Ocean warms, krill populations, that are the main food source of some species of whales, reduce dramatically, being replaced by jelly standardised salps. . Whales give birth to live young, and the mother nurses the sura with her milk and provides care. The calf is nursed by the mother for one and one half eld to three years and a mother will stay with her young three to eight years. Whales are thought to live about 40-80years. Whales vary basis of their ecosystem and what is necessary for them to survive in their ecosystem (Getten, 2006). All whales, dolphins, and porpoises species are related. fossil data has been discovered from the early Eocene epoch that point toward information that whales were already aquatic 45-50million years ago. It is thought that animals that spent a great core of time hunting for food around water areas and went through a period in an amphibious stage before becoming equal to live in the water and the animal became d edicated to the water. Records show that by in their teeth it took millions of years for true cetaceans to develop (Brakes, Simmonds 2011). The whale has adapt to the environment in many ways from the once amphibious animal it is thought to have evolved from. Fossil evidence reveals that after prehistoric whales pertinacious to be aquatic, it did not take long for bones of the hind limbs to disappear. The previous limbs evolved into flippers and the powerful tail is their most important forward motion mechanism. Anatomically, dolphins bodies have neutered to become more efficient to move in the water. Whales, like dolphins are marine mammals and like all mammals they require atomic number 8 to survive. conflicting other sea creatures such as fish, a whale would foul in water if it did not have a blowhole for oxygen. The blowhole is situated on or near the top of their head and acts as an airway passage for breathing. Whales cannot breathe through their mouth because the esophagus (food passage) and windpipe (oxygen passage) are completely separated from each other. Although whales must breathe oxygen they can spend up to 90% of their lives underwater. The eyes of a whale are relatively small when compared to the rest of its body. Their eyes are intimately adapted to aquatic life and secrete oil used to lubricate and protect their eyes from debris and other chemicals in the ocean.They are not capable of secreting tears as humans do, but their cries can be heard vocally from many miles away. They have a condensed body with a somehow a tapered head that caused the vertebrae neck to fuse together. instead of a main blood supply to the brain on the out(prenominal) of the neck, the whale blood flows through an artery in the vertebrae that supply a continuous supply of blood, which is most vital when diving into the depths of the ocean. The skin of a whale is extremely smooth, hairless, dense, and not do have glands. Their skin is unplowed smooth by c ontinuously sloughing off and being restored. On average their skin is restored at a speed nine propagation faster than a human. Whales have a tendency to depend on their sense of hearing to survive. Other senses have had to adapt for survival in the blackness of the oceans deepness.The structure of the whales melon (the fatty tissue in front of the blow whole) functions as a lens to direct sound when the dolphin generates high pitched clicks for echolocation. When the sound echoes back the small bone under the chin, called trepan bone, receives the sonic topic and stimulates the brain by means of the inner ear. By means of echolocation, whales can estimate withdrawnness by measuring the time between release the clicks and the return of echoes. Through this incredible susceptibility, whales can consider the size, shape, direction of movement, and distance of objects in the ocean water (Getten, 2006). In conclusion dolphins have adapted agreeably to survive in the depths of the ocean, seven seas and in large rivers systems. They have evolved in structure and ability to reproduce successfully and flourish. Having the intriguing ability of echolocation provides whales considerable advantage while eating in the environment in which they live. They are extremely energetic, gentle, and intelligent. The only main threatsto whales are humans through various ways and climate change. If whales are left alone in their ecosystems their species would be able to survive successfully.References Brakes, P., & Simmonds, M. P. (2011).
