How a giraffe go trough a metamorphosis?

Giraffes do not undergo metamorphosis in the way that insects or amphibians do; they develop through a more straightforward growth process. From birth, a giraffe calf is relatively developed and quickly learns to walk and run to evade predators. Over time, it grows taller and matures physically and socially, but this is a gradual growth rather than a transformation from one distinct form to another. Thus, while they do mature and change, it's not classified as metamorphosis.
