Why do fish suffocate on land?

The more surface area there is in the gills, the more oxygen can be absorbed. In water, the projections on the gills float, so each is surrounded with water from which it can absorb oxygen. On land, these all collapse together, blocking most of the surface area. So they don’t work well and the fish suffocates.

Why tadpoles Cannot live on land?

As they grow and get older, their gills start to recede into their bodies. Legs develop first, followed by arms.
