==== Hypoxia/anoxia intolerance ====
Research on intolerant ectotherms is more limited than on tolerant ectotherms and intolerant endotherms, but it is shown that anoxia/hypoxia intolerance is different in terms for how long the intolerant survive as opposed to the tolerant between endotherms and ectotherms. While intolerant endotherms only last minutes, intolerant ectotherms can last hours, such as subtidal scallops (''[[Argopecten irradians]]'').<ref name="Ivanina_2016">{{cite journal | vauthors = Ivanina AV, Nesmelova I, Leamy L, Sokolov EP, Sokolova IM | title = Intermittent hypoxia leads to functional reorganization of mitochondria and affects cellular bioenergetics in marine molluscs | journal = The Journal of Experimental Biology | volume = 219 | issue = Pt 11 | pages = 1659–1674 | date = June 2016 | pmid = 27252455 | doi = 10.1242/jeb.134700 | bibcode = 2016JExpB.219.1659I }}</ref> This difference in intolerance could be due to a couple of different factors. One advantage is that the ectothermic inner mitochondrial membrane is less leaky, so less protons will leak through the inner membrane due to differences in the [[Lipid bilayer|phospholipid bilayer]] composition.<ref name="St-Pierre_2000" /> Another advantage ectotherms tend to have in this category is an ability for their mitochondria to properly function in a wide range of temperatures, such as the western fence lizard (''[[Western fence lizard|Sceloporus occidentalis]]).'' While western fence lizards are not considered a hypoxia-tolerant animal, they still showed less temperature sensitivity in their mitochondria than mice mitochondria.<ref name="Berner_1999">{{cite journal | vauthors = Berner NJ | title = Oxygen consumption by mitochondria from an endotherm and an ectotherm | journal = Comparative Biochemistry and Physiology.
