Part of speech: noun

Definitions

1. An acoustic navigation strategy found in various species utilizes emitted sound waves for object detection, distance measurement, and size identification
2. A sound-based locating method employed by some animals helps them identify objects, gauge distances, and discern sizes or shapes in their surroundings
3. A natural sonar mechanism used by certain animals to navigate or find objects by emitting sound pulses and listening for echoes

Etymology: "Biosonar" is a compound built from "bio-", the combining form meaning "life" or "living things", taken from Greek "bios", and "sonar", a term for detecting objects underwater using sound. Sonar itself is an acronym, formed from "sound navigation and ranging", and it was coined during the Second World War to name the technology. Putting the two together describes the same principle in living creatures: an animal emits sound and reads the returning echoes to find its way or locate prey. The compound is a plain, transparent formation rather than a story of its own. Its interest lies in the logic of the blend, since the sonar half was a wartime technical term adopted into everyday scientific use, and the bio- prefix simply marks that the system belongs to a living body instead of a machine.

Synonyms: sonar, echolocation, bioacoustics, sound navigation, acoustic imaging
