Research on the cognitive capacities of dolphins and other cetaceans (whales and porpoises) has importance for the study of comparative cognition, particularly with other large-brained social mammals, such as primates. One of the areas in which cetaceans can be compared with primates is that of object manipulation and physical causality, for which there is an abundant body of literature in primates. The authors supplemented qualitative observations with statistical methods to examine playful…

Current cognitive studies on cetaceans

Some recent cognitive studies, including those on tool use, object play, self-recognition, theory of mind, and complex social systems (which require higher cognitive ability), are reviewed to compare the cognitive abilities of cetaceans to those of other members of the “cognitive triangle,” including primates and corvids.

Cognitive enrichment for bottlenose dolphins (Tursiops truncatus): evaluation of a novel underwater maze device.

The UMD is a safe and practical device for captive dolphins, and it now requires further testing on other dolphins, particularly females, to in order to examine whether the sex differences observed are a general phenomenon.

Object manipulation and play behavior in bottlenose dolphins (Tursiops truncatus) under human care

Analysis of bottlenose dolphin interactions with man-made objects introduced to their habitat as part of an environmental enrichment program shows that young dolphins displayed more playful actions towards the introduced objects than their older conspecifics.

Play Behavior in Two Captive Bottlenose Dolphin Calves (Tursiops Truncatus): Ethogram, Ontogeny, and Individual Differences

This research presented the first peer-reviewed description of a play ethogram in bottlenose dolphin calves whose behaviors were grouped into three hierarchical levels: two categories: solitary and social play; four subcategories: locomotor, object, bubble play, and in the presence of humans, and 35 entries.

The Marine Mammal Captivity Issue: Time for a Paradigm Shift

The time is ripe for the “captivity industry” and cetacean advocates and scientists to come together to create a paradigm shift in how the authors relate to cetACEans from exploitation to one of recognizing their need to be in their natural environment.

Cetaceans and Primates: Convergence in Intelligence and

St striking differences in cortical organization in the brains of cetaceans and primates along with shared cognitive capacities such as self-awareness, culture, and symbolic concept comprehension, tells us that cetACEans represent an alternative evolutionary pathway to complex intelligence on this planet.

Developing welfare parameters for bottlenose dolphins (Tursiops truncatus) under human care

Welfare science is now an established discipline which enables objective measurements of animal welfare to be made. Bottlenose dolphins (Tursiops truncatus) are a common cetacean species kept in

Bottlenose dolphins (Tursiops truncatus) moan as low in frequency as baleen whales.

The data suggest that moans are signals of anticipating physical satiation provided by humans, i.e., feeding or petting, and verification of moans in other populations and experimental investigation of the properties of moan production and perception are required.

Assessing the effectiveness of environmental enrichment in bottlenose dolphins (Tursiops truncatus).

It is demonstrated that dolphins do not treat all objects provided to them as "toys", and behavioral changes in the animals subsequent to the introduction of objects do not necessarily indicate an enrichment effect of the objects; rather, the motivation for the dolphins' behaviors toward the objects must be investigated.

Communicative and other cognitive characteristics of bottlenose dolphins

The uncertain response in the bottlenosed dolphin (Tursiops truncatus).

Human and dolphin uncertain responses seem to be interesting cognitive analogs and may depend on cognitive or controlled decisional mechanisms, and the capacity to monitor ongoing cognition, and use uncertainty appropriately, would be a valuable adaptation for animal minds.

Imitative Behaviour By Indian Ocean Bottlenose Dolphins (t uRsiops Aduncus) in Captivity

It is proposed that the tendency to imitate may be genetically programmed in delphinids to operate in the selection of compatible sexual partners, in the reinforcement of social bonds and in the strengthening of group cohesiveness.

Evidence of self-awareness in the bottlenose dolphin (Tursiops truncatus).

This chapter reports on the results of a series of studies utilizing a mirror to assess whether dolphins recognize contingent representations of themselves or use the mirror to examine an area of the body not otherwise visible that has been marked with a highly salient substance.

Ring bubbles of dolphins.

How dolphins create and play with three types of air-filled vortices, one of which is the ejection of bubbles which, after some practice on the part of the dolphin, turn into toroidal vortex ring bubbles by the mechanism of baroclinic torque.

Results show that the encephalization level of Homo sapiens is still extraordinary relative to that of nonhuman species, but a subset of delphinid odontocetes are significantly more highly encephalized than the most highlyEncephalized anthropoid primates and narrow the gap in encephalizations between humans and nonhumans substantially.

Animal play : evolutionary, comparative, and ecological perspectives

The evolutionary origins of play revisited, and glimpses into the structure and function of mammalian playfulness in the Macropodoidea, are explored.

Can we Communicate with Other Species on this Planet

Preliminary discussions of the possibility of communication with extraterrestrials requires a careful examination of (1) our own species specific or anthropocentric biases regarding the subject, (2)

Social tradition and the use of tool‐composites by wild chimpanzees

Use of more than one kind of tool for a single task, a tool‐composite, by wild chimpanzees (Pan troglydytes) demonstrates high intelligence and motor control which requires foresight, understanding of relations among tools and task, and behavioral coordination.
