Dolphins are not fish. They are mammals that live in the water. Dolphins are among the most intelligent animals on Earth. Although they can be found in all the oceans in the world, dolphins prefer coastal waters and bays. The size of dolphins varies greatly. The smallest dolphin is just about 50 kg in weight and 1.2 m in length while the largest one can weigh up to 8,200 kg and is 10 m long. Dolphins are carnivores and they eat mainly fish. A female dolphin gives birth to one calf every 2 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 pollution of their habitat and accidental entrapment in fishing net.
