Sand Tiger Shark - Behaviour

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 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)

    The quality of moral behaviour varies in inverse ratio to the number of human beings involved.
    Aldous Huxley (1894–1963)

    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)
