Reptiles need land too. Fish do not.
They are fish. They ONLY live in water.
Lungs. Only fish and some amphibions have gills.Yes. They have lungs because they don't live in the water, they just tend to go into the water to moisturize or to grab a bite to eat
The only fish species that i know of that lives out of water is the dead kind.
with their fins, they can only live in water the only way to live in water is if they can hold their breath or if they have gills
......fish.
Some fish live in salt water because they just do. Some fish live in water because they were put in water. If you get a fish at home you can put it in salt or water. It also depends on there skin because the fish can have very sensitive skin and can only touch a certain kind of water
Mostly it is only the (mostly) furry mammals that have live young. There are exceptions, like certain reptiles and fish. Annelids, that is, worms, do not have live young.
Hermit crabs live on land, for they only need water to drink, not to live on/in.
No. For example all reptiles have scales.
all of them and do me a favor dont get them confused with amphipeans which live on land and in water, reptiles only can live on land, with alligators and turtles they just can hiold their breath for relatively long periods of time, and the water snakes just glide across the water
no they can not live with out water only for a week
They generally call animals that live only in water fish, but there is certain categories that they can go under. For instance, some fish are actually mammals.
