At least six major areas of cryobiology can be identified: 1) study of cold-adaptation of microorganisms, plants (cold hardiness), and animals, both invertebrates and vertebrates (including hibernation), 2) cryopreservation of cells, tissues, gametes, and embryos of animal and human origin for (medical) purposes of long-term storage by cooling to temperatures below the freezing point of water.
Technicians preparing a body for cryopreservation in 1985. Cryonics (from Greek: κρύος kryos, meaning "cold") is the low-temperature freezing (usually at −196 °C or −320.8 °F or 77.1 K) and storage of human remains in the hope that resurrection may be possible in the future.
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
Cryopreservation has long been an issue of the individual body against the body politic. Those seeking to expand their lifespan in spite of death through preservation suffer from chronic, incurable, and/or degenerative conditions, having to overcome numerous legalities regarding body disposal, human tissue storage, the rights of minors, and in ...
Vasomotor responses allow control of the flow of blood between the periphery and the core to control heat loss from the surface of the body. Lastly, the organism can show insulation adjustments; a common example being "goosebumps" in humans where hair follicles are raised by pilomotor muscles, also shown in animals' pelage and plumage.

Animals at the Attica Zoological Park outside the Greek capital were being fed frozen meals Friday as temperatures around the country reached 40 C (107.5 F) and were set to rise further, in the ...
Frozen pipes in a home during severe winter weather is a particular problem in parts of the South because such equipment is often located outside structures. But other parts of the country also ...
Such variation in body temperature is called poikilothermy, though the concept is not widely satisfactory and the use of the term is declining. In small aquatic creatures such as Rotifera , poikilothermy is practically absolute, but other creatures (like crabs ) have wider physiological options at their disposal, and they can move to preferred ...
