The clicks are emitted from the melon of the dolphin in a narrow beam. A special fat in the melon called lipid helps to focus the clicks into a beam.

Key to the echolocation calls of British bats This key is based on the typical echolocation calls as heard on a heterodyne bat detector. Some additional points relating to sonograms are included, but these are of use only with a frequency division or time expansion detector The echolocation calls of the Atiu Swiftlet resemble those of other Aerodramus spp. in their short durations (1-3 msec), peak frequencies (6-7 kHz) and broad bandwidths (3-10 kHz) but are emitted as distinct single pulses rather than the double or multiple clicks typical of most swiftlets.

Some species’ songs can be heard for miles under the water. Baleen whales emit low-frequency songs, whereas toothed whales emit whistles and clicks and use these sounds for echolocation. Most species of bats rely on echolocation to help them find prey. This is why it is no problem at all for them to be able to find prey in complete darkness.Uc7225t remote
