Dolphins are one of the fascinating creatures in the World. They are one of the friendliest creatures as well. With their joy attitude, they are incredible acrobatic skills, simply Mother Nature’s finest creations. All species of Dolphins inhabit all types of aquatic environments. They live in coastal beaches, Oceans, estuarine and even freshwater. They can also thrive in temperatures less than zero decree Celsius to more than 30 degree Celsius. Dolphins don’t have a sense of smell; they make up for it with their other senses. They can hear frequencies ten times that of a human. They have also a good sense of touch.
Fishes breathe through gills, but Dolphins breathe air using their lungs that’s why Dolphins are mammals not fish. Dolphins give live birth to their offspring. Depending on the species of Dolphin’s, they have a gestation period of around 9 to 17 months. They can also feel baby’s heartbeat. Dolphins do not have external nipples; their nipples are enclosed within mammary slits. The nipple is exposed at the gape of the calf’s jaw for feeding. There is no actual meeting season for dolphin. They mate 365 days a year. Often dolphins rest motionless at the surface of the water, breathing regularly. They may swim very slowly and steadily, close to the surface. In shallow water, dolphins sometimes sleep on the seabed rising regularly to the surface to breath.
Dolphins are mammals; they live in pods and are very cleaver. They have large brains with two hemispheres, which are able to sleep at different times. A Dolphin has a three chambered stomach, similar to an ungulate, pointing further to its evolution from a terrestrial ancestor. They do not chew their food; the mastication of their meal is taken care of in their first or fore stomach. While land mammals breathe and eat through their mouths, unlike dolphins, which have separate holes for different purposes.
