I love dolphins. It is so great that they are aquatic mammals that live in so many places.
Plus they're really friendly! How do they communicate with each other?
Dolphins communicate with clicks. They belong to the Cetacea family.
That's amazing! What is echolocation?
It is the use of a biological sonar by several kinds of animals.
Do dolphins use echolocation?
in simpler form in other groups such as shrews, one genus of megachiropteran bats ("Rousettus") and two cave dwelling bird groups, the so-called cave swiftlets in the genus "Aerodramus" (formerly "Collocalia") and the unrelated Oilbird "Steatornis caripensis".
Early research.
The term "echolocation" was coined by the American zoologist Donald Griffin, whose work with Robert Galambos was the first to convincingly demonstrate its existence in bats in 1938. As Griffin described in his book, the 18th
Marine mammals use vocalisations in many different ways. Dolphins communicate via clicks and whistles, and whales use low frequency moans or pulse signals. Each signal varies in terms of frequency and different signals are used to communicate different aspects. In dolphins, echolocation is used in order to detect and characterize objects and whistles are used in sociable herds as identification and communication devices.
