Sensing sound allows bats, dolphins, and even some humans to navigate where they cannot see.
propel that noise into fatty structures at the front of their heads, called melons. These, in turn, efficiently transmit vibrations in seawater. The waves bounce off prey or other objects, but the whales don’t rely on external ears to hear the echo . Instead, the vibrations are channeled via their jawbones, where sound is received by fat-filled cavities so thin that light can pass through them. The cavities are near the whales’ inner ears, which sense the echoing clicks.
To supplement their senses as they explore their forest and grassy meadow habitats, they might use a coarse form of echolocation, which, a mammalogist at the University of Lisbon in Portugal, calls “echo-orientation” or “echo-navigation.” This ability could “give them a hint that there is an obstacle coming,” she says, such as a fallen branch detected by the shrews’ twitters. Their bird-like sounds are faint, but audible to humans.
