Behavior
The behavior of the pygmy hippo differs from the common hippo in many ways. Much of its behavior is more similar to that of a tapir, though this is an effect of convergent evolution. While the common hippopotamus is gregarious, pygmy hippos live either alone or in small groups, typically a mated pair or a mother and calf. Pygmy hippos tend to ignore each other rather than fight when they meet. Field studies have estimated that male pygmy hippos range over 1.85 square kilometres (460 acres), while the range of a female is between 0.4 to 0.6 square kilometres (99 to 150 acres).
Pygmy hippos spend most of the day hidden in rivers. They will rest in the same spot for several days in a row, before moving to a new spot. At least some pygmy hippos make use of dens or burrows that form in river banks. It is unknown if the pygmy hippos help create these dens, or how common it is to use them. Though a pygmy hippo has never been observed burrowing, other artiodactyls, such as warthogs, are burrowers.

Famous quotes containing the word behavior:
“Reading about ethics is about as likely to improve one’s behavior as reading about sports is to make one into an athlete.”
—Mason Cooley (b. 1927)
“Fatalism, whose solving word in all crises of behavior is “All striving is vain,” will never reign supreme, for the impulse to take life strivingly is indestructible in the race. Moral creeds which speak to that impulse will be widely successful in spite of inconsistency, vagueness, and shadowy determination of expectancy. Man needs a rule for his will, and will invent one if one be not given him.”
—William James (1842–1910)
“Excessive attention, even if it’s negative, is such a powerful “reward” to a child that it actually reinforces the undesirable behavior. You need to learn restraint, to respond to far fewer situations, to ask yourself questions like, “Is this really important?” “Could I let this behavior go?” “What would happen if I just wait?” “Could I lose by doing nothing?””
—Stanley Turecki (20th century)
