0 an intelligent animal that lives in the sea, breathes air, and looks like a large, smooth, grey fish -- delfin
The latter seems to be a feature of dolphins and other cetaceans (exploited in oceanaria shows, where two performers leap and dive together).
There was no program for the labeling of shrimp products which are turtle friendly, as is the case with dolphin friendly tuna.
Thus, the dolphin developed a broad concept of imitation.
The extremely divergent nature of these features from that of other mammalian brains continues to be the centerpoint of active debate about dolphin intelligence.
It may be premature to restrict the phenomenon of culture to humans, after reflecting on the brain and behavioural evidence for social evolution in dolphins.
We have suggested several aspects of the natural history of whales and dolphins that may have promoted the evolution of these complex cultures.
If dolphins are capable of collaborative learning, based on experimental evidence of social cognition, cultural learning may prove not to be a uniquely human phenomenon.
Research on a broader range of species has been limited by an availability bias favoring the bottlenose dolphin.
