0 a process in which animals, for example bats (= small animals with wings that fly at night), find their way in the dark by producing sound waves that echo (= are heard again) when they are reflected off an object:
Dolphins locate underwater creatures using echolocation.
Future efforts that focus on developing an echolocation call library and surveying these guilds remotely could be valuable in expanding our knowledge of this guild.
These are broad groups that can be divided further by echolocation design and foraging strategy.
In the domain of vision, two main classes of such sensory substitution devices have been constructed: echolocation devices and tactile visual substitution devices.
The feeding behaviour of insectivorous bats: echolocation, foraging strategies, and resource partitioning.
We recorded the echolocation calls of passing bats for 10 min per 30-min sampling interval.
The camera-like eye is a classic example, but so are such features as hearing, echolocation and a sense of smell.
Echolocation devices provide auditory signals which depend on the direction, distance, size, and surface texture of nearby objects, but they provide no detailed shape information.
The eye provides the premier example, although just the same arguments could be put forward for any of the other sensory systems, such as olfaction, audition, echolocation and electro-reception.
