A crayfish has gills, which are specialized organs used for breathing underwater. They extract oxygen from the water as it flows over them. Crayfish do not have feathers or scales; instead, their bodies are covered with a hard exoskeleton.
Crayfish use gills to breath.
Yes, salmon have scales and gills.
yes
They do not have gills but yes, I believe they do have scales.
Crayfish exchange gases through gills located underneath their carapace. Water is drawn in through the crayfish's openings and passes over the gills, where oxygen is absorbed and carbon dioxide is released.
Gills allow animals to breath underwater.
Exoskeleton: Crayfish have a hard shell, and no bones. That makes crayfish invertebrates (no spine). Gills: Crayfish respire underwater through gills, where humans use lungs. The circulatory system is the second one, the reason for this being that crayfish have no blood vessels (and humans obviously do).
Anchovies are not birds, so they don't have feathers. Anchovies are not mammals, so they don't have fur. Ahchovies are fish, so they do have fins.
Dragons typically have scales, not fur or feathers.
do rabbit have gills
It is important that the gills of a crayfish give them a large surface area because it helps the crayfish to breathe. The bigger the surface area, the more oxygen in the crayfishes system.Ê
The grill, or gills, of a crayfish are attached to the base of the walking legs, specifically at the thorax. These gills are responsible for respiration, allowing the crayfish to extract oxygen from the water. They are feathery structures that increase surface area for gas exchange, enabling the crayfish to breathe while submerged.
