Can a fish live on land reason?

Fish get the oxygen their bodies need by pumping water over their gills. … Gills serve the same purpose as our lungs do. Gills extract oxygen from water and send it into the fish’s blood stream. For this reason, most fish, and other aquatic animals that get oxygen from water, can’t survive on land very long.

Can a fish live or move on land?

But here’s another interesting fact: Some species of fish can actually live for a few days on land and can breathe air or absorb oxygen with their skin. These are typically amphibious fish and larger underwater creatures that are capable of storing air so they can last out of the water.
