The breath is the procedure by which living beings get oxygen. This respiration can be cutaneous, pulmonary and branchial.
The animals that breathe through the gills are aquatic, for example crustaceans, amphibians, worms, mollusks and all types of fish. For example: the crab, the shark, axolotl among others.
How do animals with gills breathe?
This process begins when water flows into the gills from the mouth. The oxygen is extracted from the water by the lamellae. When the animal’s mouth is closed, the gill lining opens to release water from the body, along with the carbon dioxide that comes out as a by-product.
In most fish the gills are located on the sides of the head. But there are gills, which are found on the legs of the animal as for example in crabs.
