We all know elephants have the biggest ears. However, scientists tried to find which animal has the biggest ears for its body size. A natural history museum found out. It is the long-eared jerboa. The jerboa is a rodent. It lives in the deserts of China. It is nocturnal. This means it is active at night, but sleeps in the day.
A zoologist said the jerboa's body is 10 centimetres long. Its ears are up to 5cm long. This is 50 per cent as long as its body. Elephant's ears are 17 per cent of its body length. Jerboas live in very hot places. Their large ears release heat from their body. This helps them to keep cool.
