ekolokation
Ekolokation, often called echolocation in English, is a biological sonar system used by certain animals to determine the location, distance, size, and texture of objects around them by emitting sounds and listening for their echoes. The best-known users are bats and toothed whales (such as dolphins and sperm whales), but a few terrestrial species, including some shrews and tenrecs, also employ echolocation.
The mechanism involves producing acoustic signals and interpreting returning echoes. Emitted sounds are typically ultrasonic in
In bats, echolocation is highly adaptive: callers may switch between searching and hunting modes, adjusting frequency,
Echolocation has evolved independently in several lineages and plays a crucial role in nocturnal foraging and
