Developmental homeostasis is present not only in humans, but in animals as well. The choosing of symmetrical features over asymmetrical features have been observed in birds, lizards, Araneae, and even insects. For example, barn swallow females have been reported to prefer males whose long outer feathers are the same length on each side ...
In biology, homeostasis (British also homoeostasis; / h ɒ m i oʊ ˈ s t eɪ s ɪ s,-m i ə-/) is the state of steady internal physical and chemical conditions maintained by living systems. [1] This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance , being kept ...

The principal level of focus of physiology is at the level of organs and systems within systems. The endocrine and nervous systems play major roles in the reception and transmission of signals that integrate function in animals. Homeostasis is a major aspect with regard to such interactions within plants as well as animals. The biological basis ...
Further examinations of animals traditionally classified as cold-blooded have revealed that most creatures manifest varying combinations of the three aforementioned terms, along with their counterparts (ectothermy, poikilothermy, and bradymetabolism), thus creating a broad spectrum of body temperature types.
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
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.
Most animals have a single renal papilla. [69] In some animals, such as horses, the apices of the renal pyramids fuse with each other to form a common renal papilla, called the renal crest. [71] The renal crest usually appears in animals larger than rabbits. [68] The kidneys of bovines are multilobar with external lobation. [72]
