Behaviour
Short-finned Pilot Whales are very sociable and are rarely seen alone. They are found in groups of ten to thirty, though some pods are as large as sixty. They are sometimes seen logging and will allow boats to get quite close. They rarely breach, but may be seen lobtailing (slapping their flukes on the water surface) and spyhopping (poking their heads above the surface). Before diving, they arch their tails and raise them above the surface. When coming to the surface to breathe, adults tend to show only the top of their head, whereas calves will throw their entire head out of the water. Adults occasionally porpoise (lift most of the body out of the water) when swimming particularly quickly.
They are known as the 'Cheetahs of the Deep' for the high speed pursuits of squids at depths of hundreds of metres.

Famous quotes containing the word behaviour:
“I look on it as no trifling effort of female strength to withstand the artful and ardent solicitations of a man that is thoroughly master of our hearts. Should we in the conflict come off victorious, it hardly pays us for the pain we suffer from the experiment ... and I still persist in it that such a behaviour in any man I love would rob me of that most pleasing thought, namely, the obligation I have to him for not making such a trial.”
—Sarah Fielding (1710–1768)
“The quality of moral behaviour varies in inverse ratio to the number of human beings involved.”
—Aldous Huxley (1894–1963)
“I cannot be much pleased without an appearance of truth; at least of possibility—I wish the history to be natural though the sentiments are refined; and the characters to be probable, though their behaviour is excelling.”
—Frances Burney (1752–1840)
