ECHOLOCATION IN DOLPHINS WITH A DOLPHIN-BAT COMPARISON
Bioacoustics, 1997ABSTRACT Dolphins possess a highly sophisticated auditory system and a keen capability for echolocation. Signals are emitted in the form of high intensity, short duration, broadband exponentially decaying pulses. The frequency spectra of echolocation signals used by many dolphins are dependent on the output intensity of the signals and not on any fine ...

Culture in whales and dolphins
Behavioral and Brain Sciences, 2001Studies of animal culture have not normally included a consideration of cetaceans. However, with several long-term field studies now maturing, this situation should change. Animal culture is generally studied by either investigating transmission mechanisms experimentally, or observing patterns of behavioural variation in wild populations that cannot be

Fibreoptic gastroscopy in dolphins
Veterinary Record, 1978Diseases of the upper gastrointestinal tract, including ulceration, infection, parasitism and the effects of ingested foreign bodies are common in captive dolphins. Using a fibreoptic colonoscope, techniques were devised for examination of the oesophagus and stomach and the removal of foreign bodies.

Acoustic reflectivity of a dolphin
The Journal of the Acoustical Society of America, 1996Backscatter measurements were made on a stationary Atlantic bottlenosed dolphin under controlled conditions. Three sets of measurements were made: (1) broadside aspect target strength as a function of frequency from 23 to 80 kHz; (2) relative target strength as a function of the polar angle about the animal using a short click signal having a peak ...
