Why is metamorphosis unique

One fine morning, Gregor Samsa, a traveling salesman, wakes up to find himself transformed as a giant bug. While his body has weirdly gone through the transformation, his mind and its fears remain the same. Incapacitated Gregor now has all the time in the world to reflect on his monotonous life devoid of passion, creativity, and meaning. Exerting pressure on an already financially stressed family, Gregor suffers shame and guilt but hopes for the transformation to be temporary and looks forward to regaining his human shape.

Meanwhile, his family confronts the crisis with a cold heart except for his sister Grete who chooses to look after her brother.

As his condition gains permanence, life in a room becomes foreign and harsh for him. The transformation makes Gregor prone to injuries resulting from an unaccustomed body engaging with an environment that is hostile to a creature like him. Wounded Gregor falls into a deep depression because of the neglect by his family members including Grete who has become indifferent to him in the wake of a tiresome routine. The story ends as Gregor, succumbing to his fate, stops eating and dies soon thereafter.

Simple in its outline and timeless in its appeal to lay bare the dark inner world of human subconsciousness, The Metamorphosis arrived in the literature world as its own expression.

Joel A. Bartsch Daniel M. Incomplete Metamorphosis — Type of metamorphosis found in insects. The insect goes through 3 stages of growth: Egg-Nymph-Adult. Insects that undergo incomplete metamorphosis include grasshoppers, cicadas, cockroaches, and lice. About 12 percent of insects make a complete metamorphosis, and amphibians are the only animal with a backbone that can do it. Humans, with our structural system intact, are not able to make such a physically striking transformation.

We are stuck or graced with our human form throughout our life. Most invertebrates pass through metamorphosis during their life cycle, but some vertebrates, such as frogs, also go through this process before reaching adulthood. Examples of metamorphosis include the tadpole, an aquatic larval stage that transforms into the land-dwelling frog class Amphibia. Starfishes and other echinoderms undergo a metamorphosis that includes a change from the bilateral symmetry of the larva to the radial symmetry of the adult.

The metamorphosis from a caterpillar into a butterfly occurs during the pupa stage. Inside the cocoon and the chrysalis, the caterpillar is transforming into a new creature.

Retrogressive metamorphosis means degenerative changes wherein an active larva metamorphoses into a sedentary adult. In Urochordata, the notochord is present only in the larval tail. Tail and nervous system are reduced in adult because the adult is sedentary. The transformation of a maggot into an adult fly and of a tadpole into an adult frog are examples of metamorphosis. Retrogressive metamorphosis is an attribute of urochordata in which an aquatic, free swimming larva with notochord transforms into an adult sessile, non chordate.

The complete loss of advanced characters present at the larval stage involves this form of metamorphosis. Retrogressive metamorphosis is a type of metamorphosis seen in Herdmania and other urochordates. It involves transformation of an active, free swimming larva with advanced characters into sedentary and simple adult.

Protochordates are an informal category of animals i. Phylum chordata has 4 sub phylums. The pharynx in protochordata is perforated by gill slits to facilitate water circulation for respiration.
