My Organism Physiology Paper As of today, there are so many organisms throughout this world that has survive the adapting to ever-changing environments. Organisms are living things such as animals, a plant or humans that can function on our own. Organisms are parts of the body that works together to help the numerous processes of life. It is very important for a living organism to adapt to the world and the changing around them, therefore the organism can be able to survive. The organism that chose to do were the dolphins. Dolphins, were helpless on land millions of years ago. Dolphins are said to be one of the inspired mammals who friendly and fun- spirited
approach has made them preferred mammals of all time and they also known for their speed and pleasing manners. It is said that researchers believes dolphins evolved from land to water because of the changing atmospheres of what happened millions of years ago. During the period, the dolphins became living being of the sea to correspond with their habitations. At first, scientists was thinking that they were land creatures.
Dolphins has lung like humans do and also come out the water for air unlike other fish do. Dolphins differs with other fish in so many ways. For example, other fish lay their eggs and the dolphins lives real births. Dolphins are warm blooded mammal that breastfeed the babies and they even had hair at some time of their lives. Dolphins can save energy by swimming beside ships that is also called bow-riding and be inherent in a group sets of five to hundreds of years. Scientists also thinks that dolphins developed echolocation to locate their kills and frequently hunt together by encircling a school of dolphins. It is also rumored that dolphins originated from the Mesonychids, a creature which existed 55 million years ago, but however on the contrary, the dolphin’s skeletal construction is like a human hand, completed with a ball and socket joint. Scientists also thinks that dolphins developed from native ancestors depending on DNA, molecular, and genetic
research. While looking at the diagram of the dolphin, I learned that they has a blow hole that let them to inhale once they emerge from the water for air. The dolphins blow hole is a specific single nose which is located on top of the dolphins head and the dolphins might clear and refill its lungs in under a 5th of a second. When the dolphins inhale, the air leaves the blow hole at rapidity of speed more than 100 miles per hour. Adapting to life underwater, the dolphins has imaginary vision in and out of the sea. Whenever light passes from air to water, it modifies speed. The dolphins produce an optical impact or refraction which modifies their eyes to see clearer. Daylight helps the dolphins see during the day and under water at night. When dolphins first began to learn how to swim, they also learn how to look and find foods.
While other animals use their legs to keep down other mammals, dolphin has to learn how to capture the food with the other dolphins which is also called a “food ball” surrounds the other fish to make a circle to enable them to catch the fish. I also learned by looking at the diagram, the main teeth of a dolphin has to adapt too. When a sharp teeth was compared to a dolphins teeth, the dolphin’s teeth were smaller with a cone shaped teeth. Dolphins has a specific gastrointestinal system which is has 3 chambered abdomens. Dolphins cannot chew their food, but instead the crushing and grinding of the mammal goes to the first or forefront abdomen, the huge majority of digestion is in the primary or second abdomen chamber and the final part of the abdomen goes to their digestion before the materials emptying inside the abdominal area. Dolphins interact with sounds or whistles to inform others that food is around or if a threat is nearby. Dolphins also has 2 kidneys like all of mammals but they are more modified
kidneys. In conclusion, today dolphins are well- adjusted to the modern life in the water. Scientists has studied for many years of what we currently understand today about dolphins from the land several millions of years ago. Dolphins are the most well liked mammals in the world. Dolphins are in information linked to whales as porpoises but physically different from whales. Dolphins are somewhat unconscious in contrast to human since they also sleep with one eye open. This provides that the knowledge of the existence of mammals.
