Lobtailing is the act of a whale or dolphin lifting its flukes out of the water and then bringing them down onto the surface of the water hard and fast in order to make a loud slap. Large whales tend to lobtail by positioning themselves vertically downwards into the water and then slapping the surface by bending the tail stock.
The killer whales regularly demonstrate their competence by chasing seals up shelving gravel beaches, up to the edge of the water. The pursuing whales are occasionally partially thrust out of the sea by a combination of their own impetus and retreating water, and have to wait for the next wave to re-float them and carry them back to sea.

Pilot whales emit echolocation clicks for foraging and whistles and burst pulses as social signals (e.g. to keep contact with members of their pod). With active behavior, vocalizations are more complex, while less-active behavior is accompanied by simple vocalizations. Differences have been found in the calls of the two species. [35]

Sperm whales have the largest brain mass of any animal on Earth, averaging 8,000 cm 3 (490 in 3) and 7.8 kg (17 lb) in mature males. [24] The brain to body mass ratio in some odontocetes, such as belugas and narwhals, is second only to humans. [25] In some whales, however, it is less than half that of humans: 0.9% versus 2.1%.
