1 Danlos syndromes symptoms and signs are joints that are more flexible than normal and loose skin that stretches away from the body.  The diagnosis of Ehlers-Danlos syndrome is based upon the clinical findings of the patient and the family history.
Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's form or structure through cell growth and differentiation.
(Dr. Girish Chandra). Metamorphosis is the transition during the life history of some animals from birth or hatching to the adult stage. Metamorphosis is considered an indirect form of development, in that a metamorphic animal passes through morphologically distinct stages before reaching the adult form.In contrast, higher animals undergo direct development in which young and old resemble one another except in size and sexual maturity.hyroid hormones function somewhat like the molting hormones of insects, in that an increase of their concentration relative to prolactin leads to metamorphosis of the larva into the adult. Prolactin functions somewhat like the juvenile hormones of insects, in that it tempers the action of the thyroid hormones.
