“This indicates that they do learn from each other, which is not a surprise really, but it does also seem that they exhibit elements of what in humans we would call ‘cultural’ behaviour”
“These are things that groups develop and are passed between individuals and that come to define those groups, such as language or dancing; and it would seem that among the Port River dolphins we may have an incipient tail-walking culture.”
