How insects decide to grow up

Like humans, insects go through puberty. The process is known as metamorphosis. Examples include caterpillars turning into butterflies and maggots turning into flies.

Is pesticide exposure reducing amphibian populations?

There have been noticeable population declines in both reptiles and amphibians because of habitat destruction and disease. In addition to immune-suppressing insecticides, the fungal pathogen, Batrachochytrium dendrobatidis, ...

Team reveals new findings about insect diversification

Biologists from the University of York have compiled two new datasets on insect evolution, revealing that metamorphosing insects diversify more quickly than other insects and are therefore the biggest contributors to the ...

Unraveling jellyfish metamorphosis

How does one genome create two completely different body plans in one animal? This was the question Konstantin Khalturin was attempting to answer when he began working on jellyfish. The fascinating story he discovered along ...

The life cycle of a jellyfish, and a way to control it

Those free-swimming jellyfish in the sea don't start out in that familiar medusa form, but rather start as sessile and asexual polyps. Now, researchers reporting in the Cell Press journal Current Biology on January 16 have ...

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 body structure through cell growth and differentiation. Some insects, amphibians, molluscs, crustaceans, Cnidarians, echinoderms and tunicates undergo metamorphosis, which is usually accompanied by a change of habitat or behavior.

Scientific usage of the term is exclusive, and is not applied to general aspects of cell growth, including rapid growth spurts. References to "metamorphosis" in mammals are imprecise and only colloquial, but historically idealist ideas of transformation and monadology, as in Goethe's Metamorphosis of Plants, influenced the development of ideas of evolution.
