Bottlednosed Dolphins

Bottlenose dolphins are among the most vocal of the nonhuman animals and exhibit remarkable development of the sound production and auditory mechanisms. This can be seen in audition, which is shown in the animals highly refined echolocation ability, and in tightly organized schools in which they live that are made up by sound communication. In testing the communication skills of dolphins, extensive studies have been done on vocal mimicry, in which the animal imitates computer-generated sounds in order to test motor control in terms of cognitive ability. Language comprehension on the other hand has been tested through labeling of objects, which has proven to be successful regarding the association of sound and object stimulus. The biggest question in dolphin communication is whether or not the species is capable of intentional communicative acts. Though results from studies have been debatable, the key to understanding the extent to this ¡§language¡¨ is to determine whether they have a repertoire of grammatical rules that generate organized sequences. In determining this, the greatest accomplishment for both the scientist and all of humanity, would be to accomplish interspecies communication, creating a bridge between humans and animals which could open up a new understanding of the unknown world of wildlife. Most importantly, it is necessary to understand the incredible aptitude of dolphin communicative skills, and the impressive intelligence the animal possesses which allows for a great deal of intraspecies and interspecies communication (Schusterman, Thomas, & Wood, 1986). The acoustical reception and processing abilities of the bottlenosed dolphins have generally been shown to be among the most sophisticated of any animal so far examined (Popper, 1980 as cited by Schusterman et al. 1986).

In order to understand the complexity of these highly mechanized acoustic systems, it is necessary to learn the process for which the dolphin hears. In most
