Dolphins are not fish. They are mammals that live in the water. Dolphins are among the most intelligent animals on Earth. They also can be found in all oceans in the world, dolphins prefer coastal waters and bays. The sizes of dolphins vary greatly. The smallest dolphin is just about 50kg in weight and 1.2 meters in length while the largest one can weigh up to 8,200kg and is 10 meters long. Dolphins are carnivores and they eat mainly fish. A female dolphin gives birth to one calf every two years after a gestation period of eleven to twelve months. A dolphin can normally live from twenty-five to sixty-five years and some species of dolphins can even live longer. Dolphin populations are at risk due to the population of their habitat and accidental entrapment in fishing nets.
