Homeothermic

Moreover, they are truly homeothermic, requiring maintenance of a constant internal body temperature that is considerably above environmental temperature. ❋ Unknown (2010)

While hibernation during the winter is found in a few arctic mammals such as the Arctic ground squirrel (Spermophilus parryii), most homeothermic animals are active throughout the year. ❋ Unknown (2009)

Reptiles are poikilothermic, which means that they can not regulate heat internally (as opposed to birds and mammals which are homeothermic). ❋ Unknown (2008)

One then makes an empirical calibration of running speed with temperature using some human runners, and goes on to construct a global temperature proxy by timing groups of wild-type human runners without knowing their nutritional status, their health profile, their homeothermic capacity or ability to sweat, their susceptibility to heat stroke, or the twitch rate of their muscles. ❋ Unknown (2006)

A large one, homeothermic, to judge from the infrared, holding still a short ways off. ❋ Anderson, Poul, 1926-2001 (1973)

Theirs was a high homeothermic metabolism, with corresponding energy demands. ❋ Anderson, Poul, 1926- (1969)

He's homeothermic; his females give live birth and nurse their young. ❋ Anderson, Poul, 1926- (1966)

Being homeothermic, and living on a planet whose slight axial tilt makes for less temperature variation than on Earth, Jovians rarely had any practical need to dress. ❋ Anderson, Poul, 1926- (1964)

At about the same time, they become homeostatic and homeothermic, as mammals are. ❋ Blish, James (1953)

As much as the presence of fur-shedding, homeothermic mammals unnerved him, he almost wished the Sst’rfleeters that Captain Krassrr had chased away had chosen to challenge Krassrr’s highly questionable plans. ❋ Michael A. Martin (2010)
