Behavior
Chinese white dolphins rise to the water surface to breathe every 20 to 30 seconds and after that, they will dive into deep water again. A calf dolphin surfaces from the water twice as much as an adult, because calves have smaller lung capacities than adults. Adult dolphins can stay underwater for about two to eight minutes, but a calf can only stay underwater for one to three minutes. Adult dolphins rarely stay under water for more than four minutes. They sometimes jump out of water, exposing their whole bodies. Besides this, white dolphins also come up vertically out of the water, exposing the dorsal half of their bodies. They have a pair of protruding eyes and they can see clearly in both air and water.

Famous quotes containing the word behavior:
“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)
“It is an open question whether any behavior based on fear of eternal punishment can be regarded as ethical or should be regarded as merely cowardly.”
—Margaret Mead (1901–1978)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
