The Complete Life Cycle of a Tadpole: From Egg to Frog The life cycle of a tadpole is one of the most fascinating transformations in the natural world.  This process, known as metamorphosis, takes an aquatic, gill-breathing larva and turns it into a land-dwelling adult amphibian. In the UK, this cycle is commonly observed in species such as the common frog and the common toad. Understanding each stage reveals how sensitive amphibians are to environmental conditions—and why their survival depends on healthy freshwater habitats. What Is a Tadpole? A tadpole is the larval stage of an amphibian, typically frogs and toads. At this stage, the animal is fully aquatic, equipped with gills for breathing and a long tail for swimming. Unlike adults, tadpoles initially resemble small fish more than frogs, lacking legs and lungs. Stage 1: Eggs (Spawn) The life cycle begins in water, where adult amphibians return to breed in spring. • Frogs lay eggs in large clumps known as spawn • Toads lay egg...
