Instead, they mostly use echolocation because they are usually only awake at night. This mechanism allows them to catch their prey in the dark and determine if there are any obstacles in their flight path. Dolphins also use echolocation to catch their prey, although how this works isn’t ...
Some porpoises appear to use rhythmic patterns of "echolocation" clicks as communicative signals. When a whale makes a low-frequency sound for communication, the sound may echo from the seafloor and possibly provide the whale with important information about its environment. Research on the evolution...
The results confirmed that sighted people are able to use self-generated echoes to navigate in a complex environment. The inter-individual variability and the quality of echolocation tasks seems to depend on how and how much the space is explored....
Discover what echolocation is, why it evolved and which animals use it, as well as exactly how bats, dolphins, whales and other animals use echolocation.
