Behavior
Manis crassicaudata is solitary, mostly nocturnal and terrestrial. In habitats such as Sri Lankan rainforests, they may be more arboreal, using their claws and prehensile tails as supports to readjust forelegs as they climb. These pangolins dig their own burrows in the ground, at depths of 1.5–6 m, these are frequently under large rocks and the entrance is often hidden with soil. When in danger, they roll up into balls, their large tails are pressed tightly against their faces and belly to help protect themselves. Longevity of this animal in captivity can exceed 19 years.
These pangolins are not often observed in the wild due to their solitary, secretive and nocturnal nature. A loud emission of a hissing sound has been reported when they are frightened or angry. M. crassicaudata possesses anal glands which emit a strong and musky-smelling yellow fluid, possibly used for marking or defense.

Famous quotes containing the word behavior:
“... two men could be just alike in all their dispositions to verbal behavior under all possible sensory stimulations, and yet the meanings or ideas expressed in their identically triggered and identically sounding utterances could diverge radically, for the two men, in a wide range of cases.”
—Willard Van Orman Quine (b. 1908)
“Temperament is the natural, inborn style of behavior of each individual. It’s the how of behavior, not the why.... The question is not, “Why does he behave a certain way if he doesn’t get a cookie?” but rather, “When he doesn’t get a cookie, how does he express his displeasure...?” The environment—and your behavior as a parent—can influence temperament and interplay with it, but it is not the cause of temperamental characteristics.”
—Stanley Turecki (20th century)
“He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one.”
—Henry David Thoreau (1817–1862)
