Sea snakes are an animal of the family Elapidae. Compared with snakes that live on land, they live in water and their living environment is very different. Sea snakes are a relatively ancient species, and snakes on land evolved from sea snakes. However, sea snakes can not live on land, they can only live in water. They can stay on land for a short period of time and then need to return to the water immediately. However, although they can only live in water, they can not stay in water all the time, because they can not breathe in water, can not breathe oxygen in water, so they can only breathe out of water.
As mentioned above, sea snakes are creatures that live in the water. They have adapted to the environment in the water during their long survival process. The environment on land is not very suitable for them. Therefore, sea snakes can not stay out of the water for too long. They can stay on land for a period of time, but not too long, once too long, they are easy to die.
Of course, sea snakes can't stay underwater all the time, because they need to come out of the water to breathe. Specifically, sea snakes use their lungs and some mucous membranes in their mouths to breathe. When they breathe, they will raise their heads above the water and return to the water after breathing. After each breath, sea snakes can persist for a long time, sometimes for several hours without breathing, and they will stay in the water during this process.
