Behaviour
The common planigale makes its living on the ground where thick cover is present to protect it from predators. Its flattened skull allows it to slip through narrow crevasses, holes, and stands of grass to escape quickly or hunt for its prey. Community nests are often built. In captivity, females make small, saucer-shaped nests out of bark and grass; it is assumed that they do the same in the wild. The species is primarily nocturnal, though in the winter it will come out to forage for food in the daylight if conditions are favourable. If conditions are unfavourable, individuals may enter a state of torpor. In this state, metabolism is suppressed, decreasing oxygen use and lowering the respiration rate from 100/min to 15-30/min. Most species only enter torpor when food is scarce, but the common planigale has been observed to do so even when food is abundant, so air temperature may be the primary factor. While in this state, individuals curl up on their sides and tuck their heads into their stomach.

Famous quotes containing the word behaviour:
“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)
“The methodological advice to interpret in a way that optimizes agreement should not be conceived as resting on a charitable assumption about human intelligence that might turn out to be false. If we cannot find a way to interpret the utterances and other behaviour of a creature as revealing a set of beliefs largely consistent and true by our standards, we have no reason to count that creature as rational, as having beliefs, or as saying anything.”
—Donald Davidson (b. 1917)
