gills
they must breathe with lungs instead of gills
If they have gills the animal will take in oygen from the water it breathes...or if it is a mammal that lives underwater it will normally have a blow hole or such which it will rise & breathe in air.

Aquatic organisms need oxygen to survive
Dissolved oxygen in water is essential for the survival of aquatic organisms like fish and plants. It is used by these organisms for respiration, which is the process of extracting energy from food. Low levels of dissolved oxygen can lead to stress or death in aquatic life.
Aquatic snails cannot survive outside of water for extended periods of time. They need water to breathe and move properly.
No, they only breathe air. They need a place to rest above the water.
No they do not breathe under water. They have lungs. Aquatic turtles such as the red - eared slider can hold their breath for 3 - 4 hours.
Aquatic
No, soil does not require the air we breathe. Soil needs air (oxygen) to support the respiration of soil organisms and roots, which is different from the air we breathe. The exchange of gases in soil occurs through pore spaces and is essential for plant growth and nutrient cycling.
Platypuses are indeed semi-aquatic. Platypuses live and shelter in burrows dug into dry land, but they need to hunt for their food in freshwater creeks and rivers. Platypuses cannot breathe underwater.
Aquatic larvae that breathe with gills and as terrestrial adults that breathe using lungs and skin
