When iridophores are affected by axanthism, the animal typically becomes duller or darker in coloration due to a lesser amount of light reflected. [2] Typically it is only the skin that is affected, and the eyes still have iridophores. The opposite of axanthism is xanthochromism, which is an excess of yellow coloration.
The larval stage of insect development is considered by some to be a form of altricial development, but it more accurately depicts, especially amongst eusocial animals, an independent phase of development, as the larvae of bees, ants, and many arachnids are completely physically different from their developed forms, and the pre-pupal stages of ...

Aposematism is the advertising by an animal, whether terrestrial or marine, to potential predators that it is not worth attacking or eating.
