Yes, salmon have scales and gills.
Crayfish use gills to breath.
yes
They do not have gills but yes, I believe they do have scales.
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.
do rabbit have gills
Through their feathery 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
