Metamorphosis is a biological process through which an organism undergoes a marked change in form, structure, or function during its development. This process is commonly seen in species such as insects, amphibians, and some marine invertebrates. Metamorphosis typically involves distinct stages, such as larval and adult stages, and can involve profound changes in body shape, behavior, and physiology. Studying metamorphosis can provide insights into evolutionary processes, developmental biology, and ecological relationships within ecosystems.
