Explanation:
Metamorphosis is simply known as the transformation stage from an immature form to an adult form in different distinct stages. During this process of metamorphosis, the changes will be observed in the habit as well as habitat.

Retrogressive Metamorphosis is the stage of larva possess with advanced character which are 'lost' during development.
EXPLANATION:
It is a type where 'free swimming larva' with notochord changes in to sessile. This type of 'retrogressive metamorphosis' where highly 'advanced larval' forms 'ends' in a lowly organised adult.
