It’s mostly just amphibians which can live on land and water – that’s frogs, salamanders, and caecilians (slimy things that look a bit like worms or snakes).
There are also animals like penguins, turtles and seals, but these usually prefer one thing or the other. Penguins swim a lot, and they need to live by water, but they spend most of their time on land.
Why Can’t All Animals Live Both On Land And In Water?
This is mainly to do with being able to breathe – aquatic creatures (like fish) tend to have gills so they can breathe without surfacing, but some animals like penguins need to come to the surface to get some air.
Amphibians tend to breathe through their gills when they’re young, and as they mature, they then breathe through their skin, or develop lungs so they can breathe above water.
I guess you could say ducks live on both land and in the water – they float on top of the water, though, which is cheating a little bit!
