... depends who you call a "SNAKE". If you call "snake" longiformes FISHES, like eels (in fresh waters), or the conger (in salted waters): They are fishes, the have gills (scholar term is BRANCHIAE), thus they can "live" under the water. If you point at terestrial snakes that "can" swim or at some other which live most of the time in ponds or rivers or alongside, but have only aerial lungs or/and an oxygenation by the skin: Then the answer is no: They don't "live" under water; they just plunge into it, monenteanously, in apnea, to feed.
Really they do both because they need water and air
stay underneath...
All snakes swim and few snakes dive, some of the most venomous snakes in the world however dive below the water and swim there as opposed to on the surface.
The melanistic (black) form of the Eastern garter snake has white under its chin and throat. King snakes do as well. Most snakes are darker on top, lighter underneath. Also black rat snakes do as well.
Warm water is less dense.
No, it will be at the bottom - difference in density.
Yes. It can only stay above water for a couple minutes. Yea what now
Interesting observation! Water indeed expands when it freezes and is the only thing that does this! Without this unique property, we might not have any life on this planet. This allows ice to stay on top of water and life underneath to keep living.
All snakes are carnivores. Vegetables are not on the menu !
I do know sea snakes srink fresh water when it rains. The fresh rain water collects at the top before mixing with the salt water and the snakes come to the surface and drink it. I am trying to find the answer to the same question you have but for now am assuming the case of the turtles is the same as the snakes. Very few animals are equipped to drink salt water.
a ship stays on water frombuoyancy which makes it float. the saltier the water the more buoyancy there is, enabling more weight to float on top
Half fill the top dish with water, add a few drops of fragrance oil to the water, place a tealight underneath, light the wick and your room will be fragranced. Alternatively, add a spoonful or two of simmering granules to the top dish but don't use any water, then place the tealight underneath and light it. Even though the tealight may be inside the burner, always be very careful with naked flames in the home.
yes if you pour gasoline on the top the gas is an oil, and will stay on the top of the water once the gasoline burns out, so will the fire
