Dolphins, cousins to whales, member of the family Delphinidae, and an animal that captures the heart of anyone who sees one. This powerhouse of a marine mammal can swim at speeds of up to thirty-five miles per hour and renowned for the fact that they can jump out of the water, a feat meant to both conserve energy and to get places quicker. When they swim, they are as graceful as a swan and as playful as a little child. Well, read on to find out more about these amazing creatures. When you see a dolphin, you are in awe, but what sort of questions do you ask? How do they swim so fast, what do they eat, where do they live? First, the anatomy of a dolphin. We’ll start with a dolphin’s teeth. Dolphins have eighty to one-hundred cone-shaped…show more content…

They are situated around where arms would be on a dolphin and these fins help the dolphin to steer in the water. The Dorsal Fin is attached to the top of the dolphin. This stabilizes the dolphin while it swims. Without it, the dolphin will roll upside down or do a barrel roll every time it pumps its tail up and down. The Flukes are the fins on the Dolphin’s tail. They provide the thrust needed to swim forward. It may seem weird, but the bones in a Dolphin’s Pectoral Fin look like they were originally hands, so that must mean that the dolphin is descended from land dwelling animals. When a dolphin looks for and finds food, one question might come up. How can dolphins find out where food is from so far away in cloudy water. The answer is the same as bats...Echolocation! Echolocation is a series of high frequency clicks that they send out from an organ in their head called the melon (not a honeydew or cantaloupe). The sounds travel through the water and when they hit against something solid, the sound bounces back as an echo. The dolphin then picks up the sound in its lower jaw. After the sound is picked up, it is sent to the Dolphin’s middle ear, then to the inner ear, and finally up to the
