Physiology
According to Star Trek canon, tribbles are native to the planet Iota Geminorum IV. They are essentially small bundles of fur with no visible external features. The fur of live-action and animated tribbles ranges from solid white to grey, speckled light to dark brown, yellow to reddish orange, and black. According to Leonard McCoy's dialogue their only two purposes in life appear to be to eat and to reproduce, and they perform both of these functions exceptionally well. McCoy concludes that tribbles use over fifty percent of their metabolism for reproduction and that they are born pregnant. A creature that was genetically engineered to hunt tribbles is introduced in the animated episode "More Tribbles, More Troubles".

Famous quotes containing the word physiology:
“I have more in common with a Mexican man than with a white woman.... This opinion ... chagrins women who sincerely believe our female physiology unequivocally binds all women throughout the world, despite the compounded social prejudices that daily affect us all in different ways. Although women everywhere experience life differently from men everywhere, white women are members of a race that has proclaimed itself globally superior for hundreds of years.”
—Ana Castillo (b. 1953)
“A physician’s physiology has much the same relation to his power of healing as a cleric’s divinity has to his power of influencing conduct.”
—Samuel Butler (1835–1902)
“Now the twitching stops. Now you are still. We are through with physiology and theology, physics begins.”
—Alfred Döblin (1878–1957)
