Gills in stingrays work just like gills in other fish. The membrane of gills are thin sheets of soft tissue filled ” like our own lungs ” with millions of blood vessels. Because the skin of fish is semi-permeable, when water passes over them oxygen moves from the water into the bloodstream of the stingrays.

Like all fish, stingrays breathe underwater but they don’t take water in through their mouths and pump it through their gills as fish do. Instead, stingrays have spiracles which are openings they use for gas exchange.
Do stingrays breathe oxygen?
Stingrays have accessory respiratory openings called spiracles just behind the eyes on top of the head. When resting in sandy or muddy bottoms, water cannot be taken in through the mouth for respiration. The spiracles then open so the stingray can pass water over the gills and obtain oxygen.
Manta’s are cartilaginous fishes, meaning they are close relatives of sharks and other rays. Being fish, they don’t breathe air, but instead they have gills allowing them to respire underwater. To breathe they must continually keep water flowing over their gills.
Do stingrays have gills?

Do sharks breathe through gills?

Here’s the quick version of how it works, according to Sharkopedia: As water passes over the gills, small capillaries allow oxygen to enter the bloodstream.
Is a stingray a shark?
