Bats and echolocation – how does it work?
Echolocation is a fascinating process whereby animals are able to emit calls into their surrounding environment and listen for the returning echoes from objects around them. This process not only allows animals to navigate successfully in their environment but also allows successful the detection of prey.Bats are one of a few mammals who use echolocation. They usually reside in environments of total darkness so it is not surprising that these animals have adapted to successful avoid obstacles in their flight path. As bats are nocturnal (they are usually active at night), their echolocation gives them a great advantage in foraging for food as there are more prey available (many inspects are also nocturnal), there is less competition for food and there is also fewer predators who prey on bats.To use echolocation, bats have adapted to the processing of large amounts of information and rapid movement in response to this information. Researchers have been analysing the brains of bats to see...
