Behaviour
The sand tiger shark is an active night feeder. It is the only shark known to gulp air and store it in the shark's stomach, allowing the shark to maintain near-neutral buoyancy which helps it to hunt motionlessly and quietly so as not to alert its prey. The sand tiger shark has been observed to gather in hunting groups with other sand tiger sharks when preying upon large schools of fish. The sand tiger shark also gathers in numbers when hunting large prey or when mating. As the shark matures, it tends to eat larger prey including other sharks, dolphins, and swordfish. Biologists have observed that the shark will usually swallow its prey whole, which if the prey is too large can lead to health problems for the shark such as esophagus, heart, and liver damage.

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)
“... into the novel goes such taste as I have for rational behaviour and social portraiture. The short story, as I see it to be, allows for what is crazy about humanity: obstinacies, inordinate heroisms, “immortal longings.””
—Elizabeth Bowen (1899–1973)
“The quality of moral behaviour varies in inverse ratio to the number of human beings involved.”
—Aldous Huxley (1894–1963)
