Document Summary

In the first one, the lamellae are covered with a lot of cells, and you see the same thing in the picture at the top: so when there is a lot of oxygen, they cover their gills to minimize salt/water balance, when you put a fish in hypoxic water for a couple of days and oxygen demand goes up, it will uncover the gills which increases surface area for oxygen uptake, and if you put it back in regular water it will recover its gills, what happens if you take a fish and put it in ion low water , more clumps on gills which are ion transporting cells and lamellae are thicker which tells us that gas transfer will be less efficient, gills that have gills like that are less tolerant to low oxygen levels.
