Metamorphosis

The video explains metamorphosis, a process of significant physical changes in animals. It covers complete metamorphosis in butterflies and frogs, detailing stages from egg to adult. Butterflies undergo four stages: egg, larva, pupa, and adult, while frogs start as eggs, become tadpoles, and mature into frogs. Incomplete metamorphosis is illustrated with grasshoppers, which develop from eggs to nymphs and then adults. The video highlights behavioral changes accompanying physical transformations.
