Yes,a few fish can live out of water - some for hours,are days,are years! Mudskippers hop around on land and even climb trees.so do climbing perch. They have a special-chamber in their gills to help them breathe. Some fish have gills- and lungs,too!Its lungs help the lungfish spend a lot of time on land. In summer.While it is sleeping, the lung fish breathes air through a little. Mudskippers
Fish need to breathe the gas called oxygen in order to live. Oxygen is in the air and in the water,too. They have gills.gills can take oxygen from water. Then the water goes out of the fish’s body through openings behind the gills. Gills
If the pond is frozen solid from top to bottom,then fish can’t live there This sheet of ice has water below it, where fish can live. They usually stay near the bottom of the pond,where the temperature is warmer. Frozen only the surface water gats frozen the water in the bottom is not frozen. So the fish can live there.
