Kinda-sorta. Sharks are fish, they use gills to get oxygen from the water. So it's a kind of breathing even if there are no lungs involved.
Yes, because when frogs are tadpoles they need to be able to breath under water so they have gills and when they turn into frogs they still have their gills but they form lungs so they can breath on land.
Yes. The fish does not use its mouth to breathe. It uses its gills.
They have gills under their mouths that allow them to breathe. When the gills start to dry out, foam forms at the mouth, telling you that the crab has trouble breathing.
It is simple, it uses breathing tubes and go tothe surface of the water to get air and closes the tube when it go in the water.
A sea cucumber is an animal that can breathe through its anus. It uses a process called cloacal respiration to absorb oxygen from the water.
The ability of a diver to cut through water in a swimming pool demonstrates the property of viscosity in matter. Viscosity is the measure of a fluid's resistance to deformation under shear stress. In this case, the water's viscosity allows the diver to move through it by exerting force.
Because there are many harmful sea animals who can harm humans and there is no oxygen under the sea to breathe in.
All insects breathe through spiracles, except for insects that live in the water. A water stick insect breathes through an air tube.
A barracuda is a fish and like other fish it uses gills to extra oxygen from the water in which it swims.
