Why do tadpoles come up for air?

Introduction: Understanding the Tadpole Life Cycle

Tadpoles are the larval stage of frogs, a phase in which they undergo several physical and physiological changes before transforming into adult frogs. During their early life, tadpoles live entirely in water and breathe through gills. However, as they grow, they develop lungs and can breathe both in air and underwater. Tadpoles are an essential part of the ecosystem, and their adaptation to different environments has been a subject of study for many scientists.

Respiratory System of Tadpoles: Gills or Lungs?

The respiratory system of tadpoles consists of two types of organs: gills and lungs. During the early life stages, tadpoles rely on their gills to extract oxygen from water. Gills are delicate fronds that absorb oxygen from the water and release carbon dioxide. As tadpoles grow, they develop lungs, which allow them to breathe air. The lungs of tadpoles are simple sacs that exchange gases by diffusion. As a result, tadpoles can breathe both in water and air, depending on their needs. However, their ability to breathe air does not mean they can survive for long periods outside of water.
