 | | The humpback dolphin has an unusual diving posture, first lifting its beak out of the water and arching its back, and then pausing before dipping below the surface or flipping its tail to dive (2). |
 | | Despite this sluggishness, many aerial displays are seen; including breaching, when the dolphin leaps out of the water, lob tailing (slapping the surface of the water with the tail) and spyhopping, when the dolphin raises its head vertically out of the water and then sinks below the surface quietly (6). |
 | | Indo-Pacific humpback dolphins are at risk from factors that also threaten all other cetaceans, such as entanglement in fishing nets, pollution and the depletion of fish stocks worldwide (6). |
