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.

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.
