Question

Comperison between fish and frog-adaptation?

Answer 1

The big difference is that frogs are amphibians and breathe air. Most frogs lay their eggs in water and in the larval stage (tadpoles) live in water and have gills in order to breathe; when they mature they lose their gills and tails, move onto land and breathe air, some with lungs, others by absorbing oxygen through their skin. Some frogs bypass this larval stage.

Fish live in water, and have gills to extract oxygen from the water. There are a few fish, such as the walking catfish and the betta splendens that breathe air, but very few air breathing fish exist.
