It is a gill chamber.
crab
It has gill chambers which stores water. Water contains dissolved oxygen which is needed to breathe so it can stay on land. Also, it returns to the waters once the supply of water is running out.
gill slits
Tilapia have four pairs of gills, totaling eight gill arches in their gill chamber. Each gill arch supports numerous gill filaments, which are responsible for gas exchange. This structure allows tilapia to efficiently extract oxygen from water as they breathe.
The openings in the throat region of a fish that lead to the gill chamber are called gill slits. These slits allow water to flow over the gills so that oxygen can be absorbed and carbon dioxide can be released.
Its a structure attached to the gills of crustaceans like lobsters. it sort of beats, causing water to flow in and out of the gill chamber.
First, dissolved oxygen in the water is absorbed by the creature and then it flows through the gill chambers. And the waste products flow through the gill chambers and it will be passed out through the body.
It can store water for the animal to stay out of water for a short period of Time.
yes they swallow water and expel the used water out their gills.
No, but they have gill chambers which they use to store water, to take in dissolved oxygen.
To help them breath!
