Superalliance of bottlenose dolphins [PDF]
Nature, 1999 It 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.

Congenital Scoliosis of a Bottlenose Dolphin [PDF]
Journal of Wildlife Diseases, 2011 There are many reports of cetaceans with deformed and twisted bodies. Skeletal pathology descriptions have shown changes to axial skeletons because of injury, trauma, or disease. We present a bottlenose dolphin (Tursiops truncatus) that shows characteristic patterns of congenital skeletal deformity, including malformed vertebrae, ribs, and sternum ...

Bioacoustics, 2020
Bottlenose dolphins make many different sounds that have been recorded and described by researchers for over 60 years. This species, Tursiops truncatus, is arguably the most studied marine mammal.

The Experience of Self in the Bottlenose Dolphin
Consciousness and Cognition, 1995Marten and Psarakos have presented some evidence which suggests that objective self-awareness and possibly representations of self may characterize the dolphins' experience of self. Their research demonstrates the possibility of similarities in the sense of self between primate species and dolphins, although whether dolphins have subjective self ...

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.

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

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

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.

Prosociality and reciprocity in bottlenose dolphins (Tursiops truncatus)
Animal Cognition, 2021Some moral behaviours, often regarded as reflecting high cognitive abilities (such as empathy, cooperation, targeted helping) are known to only be present in very few species, like great apes, elephants and cetaceans. Prosocial behaviours (producing a benefit for the recipient without necessarily involving a cost for the actor) have been mostly found ...

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 ...
