Catch me if you can…🐋 Orcas (Orcinus orca) hunt by echolocation, a technique that uses sound waves and echoes to identify and locate prey. Once transmitted, these sounds then bounce back from fish and other prey, and give them important information about their next snack, such as size and proximity. Meet the animals striving to survive in our fragile frozen worlds. This is life on thin ice. ❄️ #FrozenPlanet2 Find out where to watch 👉 https://www.bbcearth.com/shows/frozen-planet-2 | BBC Earth
