Some tigers compensate by crossing their eyes. When the neurons pass from the retina to the brain and reach the optic chiasma, some cross and some do not, so that visual images are projected to the wrong hemisphere of the brain. White tigers cannot see as well as normal tigers and suffer from photophobia, like albinos. [21]
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.
The tiger is popularly thought to be the largest living felid species; but since tigers of the different subspecies and populations vary greatly in size and weight, the tiger's average size may be less than the lion's, while the largest tigers are bigger than their lion counterparts.
Developmental homeostasis is a process in which animals develop more or less normally, despite defective genes and deficient environments. [1] It is an organism's ability to overcome certain circumstances in order to develop normally. This can be a circumstance that interferes with either a physical or mental trait.
Using satellite images, researchers have created a new real-time mapping system for tiger habitats that could aid in conservation efforts. How NASA and Google Earth are helping save tigers Skip to ...
Diving reflex in a human baby. The diving reflex, also known as the diving response and mammalian diving reflex, is a set of physiological responses to immersion that overrides the basic homeostatic reflexes, and is found in all air-breathing vertebrates studied to date.
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.
Fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges.
