Many whales and dolphins have markings that are individually unique. These are easily distinguished in photographs. Read More…
Playlist shuffle: the daily acoustic repertoire of bottlenose dolphins
As mentioned on the previous post , bottlenose dolphins rely on sound production for orientation, feeding and communication with con-specifics. It is therefore of great importance to study their vocalization repertoire as it can provide important information on their habitat use and responses to human induced stress. Acoustic monitoring using hydrophones (underwater microphones) to record the different vocalizations naturally produced by dolphins is particularly important in coastal habitats, where dolphins may be affected by boat traffic noise and coastal construction.
Sound travels 4 TIMES FASTER in water than air and most whales and dolphins rely on sound to communicate and find food.
Bottlenose dolphins can develop individually distinctive SIGNATURE WHISTLES in the first year of life. Somewhat like a NAME, these whistles are used to help dolphins stay in contact and address each other.
Bottlenose dolphins also use ECHOLOCATION CLICKS to find and track their prey.
Small groups join together and split up frequently. This is called a FISSION-FUSION SOCIETY.
Some individual dolphins consistently associate with each other- much like friends
