Gigantothermy (sometimes called ectothermic homeothermy or inertial homeothermy) is a phenomenon with significance in biology and paleontology, whereby large, bulky ectothermic animals are more easily able to maintain a constant, relatively high body temperature than smaller animals by virtue of their smaller surface-area-to-volume ratio.

Warm-blooded animals could have gained an advantage by creating an inhospitable environment for many disease-causing organisms, thus reducing the risk of infections. Insulation and Thermoregulation : Homeothermy could have originated as a response to the development of insulating structures like fur, feathers, or other coverings.
Male Canadian garter snakes huddle around a female after hibernation when mating.. Huddling confers higher and more constant body temperatures than solitary resting. [3] Some species of ectotherms including lizards [4] and snakes, such as boa constrictors [5] and tiger snakes, [6] increase their effective mass by clustering tightly together.
However, over the past three decades, investigations in the field of animal thermophysiology have unveiled numerous species within these two groups that do not meet all these criteria. For instance, many bats and small birds become poikilothermic and bradymetabolic during sleep (or, in nocturnal species, during the day).
The transported animals were already available for adoption in Pasadena and will now be placed up for adoption in San Diego, a news release by the shelter said. Sacramento SPCA rescues 34 animals

Animals recache the food that they've pilfered from other animal's caches. For example, 75% percent of mildly radioactive (thus traceable ) Jeffrey pine seeds cached by yellow pine chipmunks were found in two cache sites, 29% of the seeds were found in three sites, 9.4% were found in four sites and 1.3% were found in five sites over a 3-month ...
