This profound change in form and function allows a single organism to thrive in entirely different environments as it matures, solving ecological challenges that a static body plan could not. Salamanders and newts follow a similar, though often less drastic, path of transformation from aquatic larva to terrestrial adult.
What Animal Undergoes Metamorphosis Examples
Even within familiar creatures, the transformation is striking: a barnacle larva, resembling a tiny shrimp, settles and metamorphoses into the sessile, filter-feeding shell we recognize. Understanding what animal undergoes metamorphosis reveals one of nature’s most ingenious strategies for survival and reproduction, optimizing energy use and minimizing competition between juvenile and adult stages.
Sea stars, sea urchins, and many marine invertebrates have a free-swimming larval stage, like the bilateral trochophore, that is completely unlike the sedentary, radial adult form. This transition involves the resorption of the tail and the development of limbs, eyes, and a entirely new digestive system suited for life on land.

These shifts are critical for dispersal, finding food, and avoiding predators in the vast marine environment. In contrast, incomplete metamorphosis, or hemimetabolism, proceeds through a series of nymphal stages that gradually resemble the adult form, shedding their exoskeleton multiple times without a dormant phase.
