Amphibians
Some species of amphibians do not have lungs or gills, but obtain all their necessary oxygen and water through their skin. Other amphibians have lungs for breathing air, but use their skin to take in additional oxygen, as well as water, through capillaries in their skin.
The oxygen must reach the mitochondria in the animal cell. The mitochondria is responsible for aerobic respiration, which uses oxygen to break down sugar molecules and produce chemical energy in the form of ATP. Without oxygen, the mitochondria cannot generate energy efficiently.
uses for the element oxygen?

A sea cucumber is an animal that can breathe through its anus. It uses a process called cloacal respiration to absorb oxygen from the water.
