The Axolotl is an amphibian that can spend its whole life in a larval state.

The statement is true because the axolotl is a unique type of amphibian that exhibits neoteny, which means it retains its larval characteristics throughout its entire lifespan. Unlike other amphibians that undergo metamorphosis and grow into adult forms, the axolotl remains in its larval state and retains features such as gills and fin-like limbs. This adaptation allows the axolotl to live underwater and maintain an aquatic lifestyle instead of transitioning to a terrestrial environment like other amphibians.
