Bottle Nosed Dolphins Lab Report
Introduction:
Every species on this earth has the ability to sense and to survive; and in their own unique way, they communicate with the world around them. Mammals, overall, are able to communicate using vocal signals, body gestures, and chemical signals; more precisely, within the great depths of the seas, there are mammals that are able to use other ways to communicate such as sonar and song. Mammals such as the Orca, Bottle-Nosed Dolphins as well as many other species of dolphins, and different types of Whales are able to use their voices under water to detect and “speak” to other conspecifics. This range can reach distances over miles and miles away, and can also be influenced by the distance at which these different species are from …show more content…
Synchronized hydrophones were used to record the whitsles of the dolphins and their range seemed to be lower than estimated.
Another experiment tests whether or not killer whale predation affects the vocalization of different types of dolphins. Whistles, which can propagate over several kilometers, may be necessary to retain group cohesion. This type of long distance communication may also serve as a dinner bell to any killer whales in the area, and our results show that these dolphins were less likely to be vocal in the presence of killer whales (Rankin, Archer, and Barlow, 2013).
For the final experiment with the divergence of signatures in song communication between whale groups done by Rudiger and Volker in 2011, the signal signatures were classified based on spectrographic contour and stereotypy. The final results indicate that there is indeed difference between the communication signals of one group from another group. Each whale family has their own cultural aspects of song and communication that they
