There are two sea creatures commonly referred to as dolphins. One is the porpoise, which is a mammal and as such breathes air. Because they breathe air, they do not have gills.
The other dolphin is a fish. Technical name: Coryphaena hippurus. It is also called Mahi-Mahi (Hawaiian) and Dorado. This is a true fish, with gills. It cannot breathe air so its gills do not work outside of water.

Why do gills do not work outside water?
Because they can only take up oxygen from water.
Gills not function well on land?
No, gills do not work on land. Gills are used for water purpopes only, to help breathe under water.
Why do fish gills not function in air?
Lungs are what air breathing creatures use. That is how they evolved. Gills need to have water flowing over them so they work in water. So Lungs won't work in water and Gills won't work in air.
Can sea horse's stay outside of water for an hour?
No, they can only take oxygen in through its gills. Gills can not process oxygen directly. It needs the water for them to work. Take them out of the water for more than a few minutes, and they will basically die from suffocation, just like land mammals would die under the water.
What are adaptations of the fish?
All fishes are adapted to live in water because they dont have lungs they have gills which means that lungs work with air and gills work with water. Have you ever thought does a fish dies when taken out of the water it is because gills are the only way a fish breathes through. Gills work when a current of water slide over them so when the fish is taken out of the water, the gills stop working because the current of water didnt slid over it. They have wide eyes to see predators swimming around them.
How do fish get oxygen they need?
fishes uses the oxygen resolved in water.
Why are gills not suitable for breathing air?
Gills are designed to absorb oxygen only from water, and can only work if water is passing through them or they will collapse. When a fish is taken out of the water, the oxygen-absorbing filaments of the gills flatten out and the fish suffocates because it's gills are not made to absorb oxygen directly from air.The simple answer is that gills colapse when removed from water as they are adapted to water which is more dense than air.

Why can't fish breathe on land?
The fish hasgills that they use to filter from the water the oxygen they need to as you say "breath" ,so when you put them on land there gills are not working anymore by filtering the water for oxygen because there is no water it's as you know just air (oxygen) so there gills are still trying to work but there is no water to filter oxygen for them.
How does a sea star breathe?
This depends on the organisms, but many things that live in the sea breathe through gills. There is oxygen in the water so they take in water and they will diffuse the oxygen out of the water into their cells.
