Egg coats can buffer the low pH of the Moor frog's acidic habitats; [32] however, drastic decreases in habitat pH caused by human-made pollution affects an egg coat's function. [35] High habitat acidity causes thinning and a loss in the egg coat's ability to attract water. [35] Thinned egg coats are more tacky and opaque. [35]

Four-stroke buccal pumping is used by some basal ray-finned fish and aquatic amphibians such as Xenopus and Amphiuma. [1] This method has several stages. These will be described for an animal starting with lungs in a deflated state: First, the glottis (opening to the lungs) is closed, and the nostrils are opened.
