==== Reoxygenation of intolerant animals ====
While it is unclear how reoxygenation affects intolerant ectotherms at the mitochondrial level, there is some research showing how some of them respond. In the hypoxia-sensitive shovelnose ray (''[[Eastern shovelnose ray|Aptychotrema rostrata]]),'' it is shown that ROS production is lower upon reoxygenation compared to rays only exposed to normoxia (normal oxygen levels).<ref name="Hickey_2012" /> This differs from the hypoxia-sensitive endotherm, which would see an increase in ROS production. However, the ray's levels were still higher than the more hypoxia-tolerant Epaulette shark (''[[Epaulette shark|Hemiscyllum ocellatum]]''), which potentially sees hypoxia due to the bouts of low tides that can be seen in reef platforms.<ref name="Hickey_2012" />  Subtidal scallops will see both a decrease in maximal respiration and a depolarization of the membrane during reoxygenation.<ref name="Ivanina_2016" />
