Echolocation lets animals use sound as a guide in places where vision fails. They send out clicks, chirps, or taps and interpret the returning echoes to find prey, avoid danger, or move confidently in ...

Do you know which animal has the best hearing in the world? While humans stop at 20 kHz, this record-holder reaches 300 kHz ...

video: Neuroscientist Cindy Moss is investigating how animals use sensory information to guide their behavior. Her team at Johns Hopkins University's "Batlab" is currently focused on bat echolocation ...

Seba's short-tailed bat (Carollia perspicillata) lives in the subtropical and tropical forests of Central and South America, where it mostly feeds on pepper fruit. The animals spend their days in ...

Toothed whales use sound to find their way around, detect objects and catch fish. They can investigate their environment by making clicking sounds, and then decoding the “echoic return signal” created ...

Toothed whales – like dolphins and belugas – might live in the ocean, but they have some big things in common with cave-dwelling bats. They’re all mammals that live in dark places and use echolocation ...

Rescue Crew and Stranded Dolphins: IFAW personnel respond to common dolphins in Wellfleet, Mass., a global hotspot for mass strandings of dolphins. Partnerships and collaborations between researchers ...

It's now well-established that bats can develop a mental picture of their environment using echolocation. But we're still figuring out what that means—how bats take the echoes of their own ...

There's a vast world around us that animals can perceive — but humans can't. Pulitzer Prize-winning science writer Ed Yong uses the example of a dark room: Though it might seem that there would be ...

Bats live in a world of sounds. They use vocalizations both to communicate with their conspecifics and for navigation. For the latter, they emit sounds in the ultrasonic range, which echo and enable ...
