Comprehension of sentences by bottlenosed dolphins
Cognition, 1984Abstract The ability of two bottlenosed dolphins (Tursiops truncatus) to understand imperative sentences expressed in artificial languages was studied. One dolphin (Phoenix) was tutored in an acoustic language whose words were computer-generated sounds presented through an underwater speaker.

Superalliance of bottlenose dolphins
Nature, 1999It is quite common to find several levels of nested male alliances in human political organization1, 2 but these are extremely rare in other species3. Yet we found that male bottlenose dolphins (Tursiops sp.) at Shark Bay, Western Australia, form two levels of alliance within a social network of more than 400 individuals.

Visual Problem-Solving in a Bottlenose Dolphin
Science, 1964A captive 8-year-old dolphin, well adapted to contact with human beings, was tested by the discrimination method for underwater perception of visual forms or patterns. The animal successfully discriminated 21 of the 25 pairs of stimuli presented. After having learned a particular combination, the dolphin was immediately able to respond to different but

A Stingray Spine in the Scapula of a Bottlenose Dolphin
Journal of Wildlife Diseases, 1997A stingray spine was found lodged in the scapula of a deceased 272 cm, male bottlenose dolphin (Tursiops truncatus) from South Carolina (USA) following skeletal preparation, nearly 6 mo after necropsy. No external puncture wound, internal bruising, or laceration of muscle tissue surrounding the scapula was evident during necropsy of the animal ...

In-air visual acuity of the bottlenose dolphin
Experimental Neurology, 1973Abstract Using the method of constant stimuli, horizontal black and white line gratings were presented to a bottlenose dolphin in a successive discrimination task. Over a constant viewing distance of 2.8 m, a minimal visual angle of 18 min of arc was obtained. This value is poorer than that reported for pinnipeds, but comparable to functions reported

A DNA vaccine against dolphin morbillivirus is immunogenic in bottlenose dolphins
Veterinary Immunology and Immunopathology, 2007The immunization of exotic species presents considerable challenges. Nevertheless, for facilities like zoos, animal parks, government facilities and non-profit conservation groups, the protection of valuable and endangered species from infectious disease is a growing concern.

Bisalbuminemia in a bottlenosed dolphin (Tursiops truncatus)
Experientia, 1979Bisalbuminemia was found in a female bottlenosed dolphin (Turiops truncatus) on routine examination. There is no association with disease.

Sounds Emitted by the Bottlenose Dolphin
Science, 1961The sonic emissions of the bottlenose dolphin are remarkably complex. Three classes of these sounds are discussed and presented graphically. The sine-type wave whistles range in frequency from about 4000 to 18,000 cycles per second. The clicks contain components of this same frequency range plus some components of higher frequencies.

PREGNANCY IS A DRAG FOR BOTTLENOSE DOLPHINS
Journal of Experimental Biology, 2011![Figure][1] Lumbering around during the final weeks before delivery is tough for any pregnant mum. Most females adjust their movements to compensate for the extreme physical changes that accompany the later stages of pregnancy.
