Critical thermal maximum, in
zoology
Zoology ( , ) is the scientific study of animals. Its studies include the anatomy, structure, embryology, Biological classification, classification, Ethology, habits, and distribution of all animals, both living and extinction, extinct, and ...
, is the temperature for a given species above which most individuals respond with unorganized locomotion, subjecting the animal to likely death.
[R.W. McDiarmid, 1999] This concept is particularly relevant in periods of
aestivation
Aestivation ( (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered m ...

quiescence, in which circumstances an organism experiences limited mobility and lacks the ability to seek a
microhabitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ...
