“…These include the herding of fish into balls while individual animals take turns feeding (Similä & Fugarte, 1993), the intentional stranding of dolphins to catch fish they have chased onto a bank (Hoese, 1971;DuffyEchevarria, Connor & Aubin, 2008), the intentional stranding of killer whales to capture sea lion pups (Guinet & Bouvier, 1995), the use of air bubbles to confuse, encircle, and trap prey (Fertl & Wilson, 1997), and dolphins' placement of sponges onto their rostrums prior to searching the ocean floor for prey, most likely to prevent injury to their rostrums (Smolker et al 1997). Killer whales cooperate to dislodge seals and penguins from ice floes (Visser et al, 2008), and also cooperate to force large schools of herring to the surface, which makes it easier for the whales to consume the fish (Nottestad, Ferno & Axelsen, 2002). Dolphins also cooperate with humans to increase the foraging success of both species.…”

The nature and extent of dolphin intelligence has long intrigued humans. Unequivocal answers to the question "how intelligent are dolphins?" have proven evasive due to both the existing myriad views of intelligence and the ambiguity of much spontaneous dolphin behavior. In this paper, we focus on one aspect of intelligence, namely the ability to plan one's behavior in a meaningful way. The generalized ability to create novel and appropriate behavioral plans when confronted with new problems has obvious evolutionary advantages, but has been found in relatively few species. The studies reported in this paper demonstrate planning behaviors in bottlenose dolphins (Tursiops truncatus) in conditions quite different from those that occur during dolphin foraging and mating (two areas in which wild dolphins may engage in planning). The dolphins' ability to plan their behaviors in these novel contexts provides additional evidence that generalized planning ability is not unique to humans, and demonstrate that human-like language is not required for generalized planning skills. These findings also suggest that in addition to species niche specific cognitive abilities, generalized cognitive abilities may play an important role in the evolutionary success of some species.

“…Así, la orca tipo A sería un predador generalista (Pitman et al 2011), lo cual concuerda con las observaciones anteriores para Chile. La orca tipo B se alimentaría preferentemente de focas y lobos marinos aunque ballenas minkes y pingüinos también son parte de la dieta en aguas antárticas (Pitman & Ensor, 2003;Visser et al 2008;Pitman & Durbam, 2010, mientras que la tipo C consumiría principalmente bacalao antártico (Dissostichus mawsoni) (Pitman & Ensor, 2003). Se desconoce la dieta de la orca tipo D, pero se ha sugerido que podría incluir peces (Pitman et al 2011).…”

“…(Connor 1995a). In many cases, individuals may enhance the by-product benefits they receive by coordinating their behaviour with others, as in fish driving by cormorants (Bartholomew 1942) or killer whales that cooperate to create waves that wash seals off ice flows (Smith et al 1981;Visser et al 2008).…”

Players in Axelrod and Hamilton's model of cooperation were not only in a Prisoner's Dilemma, but by definition, they were also trapped in a dyad. But animals are rarely so restricted and even the option to interact with third parties allows individuals to escape from the Prisoner's Dilemma into a much more interesting and varied world of cooperation, from the apparently rare 'parcelling' to the widespread phenomenon of market effects. Our understanding of by-product mutualism, pseudo-reciprocity and the snowdrift game is also enriched by thinking 'beyond the dyad'. The concepts of by-product mutualism and pseudo-reciprocity force us to think again about our basic definitions of cooperative behaviour (behaviour by a single individual) and cooperation (the outcome of an interaction between two or more individuals). Reciprocity is surprisingly rare outside of humans, even among large-brained 'intelligent' birds and mammals. Are humans unique in having extensive cooperative interactions among non-kin and an integrated cognitive system for mediating reciprocity? Perhaps, but our best chance for finding a similar phenomenon may be in delphinids, which also live in large societies with extensive cooperative interactions among nonrelatives. A system of nested male alliances in bottlenose dolphins illustrates the potential and difficulties of finding a complex system of cooperation close to our own.
