What do amphibians typically have during their early life stages?

Amphibians typically have gills during their early life stages, particularly while they are in the larval stage. For example, frog tadpoles and salamander larvae breathe through gills, which allow them to absorb oxygen from the water. This aquatic adaptation is essential for their survival before they undergo metamorphosis and transition to life on land, where they develop lungs for breathing air.

Fins are characteristics of fish, which are closely related to amphibians but are not features of amphibians in their early stages. Scales are also common in fish and reptiles but are not found on amphibians during any life stage. Claws are not a typical feature of amphibians either; they mainly have webbed digits or toes adapted for different habitats, both aquatic and terrestrial.
