1. Insects: Many insects, such as butterflies, beetles, and flies, have a distinct larval stage that looks different from the adult. For example, butterfly caterpillars have a worm-like appearance, while adult butterflies have wings.
2. Amphibians: Amphibians, including frogs and toads, have a larval stage called a tadpole that lives in water and breathes through gills. Tadpoles have a long tail and lack limbs, while adult amphibians develop legs and lungs for terrestrial life.
3. Fish: Some fish species have a larval stage known as a fry, which can look different from the adult fish. For example, the fry of certain fish species may have a different body shape or coloration compared to the adults.
4. Reptiles: While many reptiles, such as snakes and lizards, have young that resemble the adults, some species, like turtles, have hatchlings that look distinct from adult turtles.
So, while some animals with three stages of life may have similar appearances between the young and adults, it is not a universal characteristic across all species.
