Echolocation: Bats and whales behave in surprisingly similar ways


echolocation batSperm whales weigh up to 50 tons, and the smallest bat barely reaches a gram. Nevertheless, the two species share the same success story: They both have developed the ability to use echolocation — a biological sonar — for hunting. Now researchers show that the biosonar of toothed whales and bats share surprisingly many similarities — even though they live in very different environments and vary extremely in size.
