Metamorphosis is a biologically regulated developmental process in which an organism undergoes a marked, genetically programmed reorganization of morphology, physiology, and often ecology between early and adult life stages. It is classically characterized in holometabolous insects, amphibians, and some marine invertebrates, where endocrine signaling (e.g., ecdysteroids, juvenile hormone, thyroid hormones) orchestrates cell proliferation, apoptosis, tissue remodeling, and organ differentiation. Metamorphosis often separates larval and adult niches, optimizing resource use and dispersal. At the research level, it serves as a model for studying hormone-driven gene regulatory networks, developmental timing, phenotypic plasticity, and evolutionary transitions between life-history strategies.
A new study led by researchers from the Museum für Naturkunde Berlin reveals how the loss of large mammals can ripple through ecosystems in unexpected ways, even affecting amphibian larvae living in temporary ponds. By examining ...

All living beings, big or small, are formed through the hard work of many different cells. To keep the body ready for any challenge, cells need to be dynamic. Often, this means the same types of cell—for example, red blood ...

The ascidian Ciona, a genus of sea squirts, undergoes metamorphosis from active, tadpole-like larvae to sessile adults. Metamorphosis begins when Ciona larvae attach themselves to rocks or other surfaces, typically several ...
