As far as I am aware, there is no sea creature that needs to be physically on land to breathe, but there are a number of sea creatures that can breathe air, either exclusively or in tandem with breathing in water.
All sea mammals and reptiles (such a whales, dolphins, porpoises, walruses, seals, sea lions, crocodiles, turtles, sea snakes, etc.) can only breath air, so they must surface. There are a number of fishes, like lungfishes and mudskippers than can both breathe in water and in air.
fire can not breathe because it's not human so if you think fire could breathe yo got it wrong fire can't
Any creature that lives entirely on land is said to be a terrestrial animal.
They don't, any aquatic reptile needs to return to the surface to breathe after a while, the only creatures that can breather underwater are fish (and all their variants ie: sharks, stingrays etc)
Mind Control must target a creature. Even though the land enchanted by Wind Zendikon is still a land, it is also a creature and can now be targeted by any card that can be used against them.
For any creature to be able to breathe, there has to be something to breathe. Space is vacuum, an empty nothing. No creature can get anything from nothing. So no, a turtle wouldn't be able to breathe in space. Unless you provide it with an atmosphere, like in a space station, space ship or a space suit. Then a turtle most likely would breathe just fine.
Penguins are birds, they are not fish, even though they do swim very well. They have lungs and the breathe the same way that any other bird breathes.
You can"t be any creature you can only be people
Any creature that only eats grass such as a deer, cow, or horse.
A seadarell is any water creature that lives in the water.Nick hill (squar headed kid) is the only kid that would call a sea creature that but that's just him.
This is usually only available through some type of fossil, unless the creature is still living and is observed directly.
Through their nostrils, much like other land-based mammals.The same way as any other air-breathing animal does - through their lungs !They breathe through their nostril's, mouths and lungs.
Any kind or flesh-eating creature would only eat a dead elephant
