Elephants are the largest land animals on Earth, with males measuring up to 3 meters and females up to 2.5 meters. They can weigh up to 7,500 kilos and live 60-70 years. Elephants are known for their intelligence and have a sophisticated sense of smell and hearing. They live in herds in Africa and Asia and feed on grass, plants, and up to 270 kg of food per day. However, they are endangered due to poaching for their tusks.
