SECRET OF CHAMELEONS' COLOR CHANGE

It    is   the  light  reflecting  cells  in   the  skin  that   provide  chameleon   their  uncanny   color-changing   abilities  that  help  them  attract  mates   and  ward  off  predators .Unlike  other  animals   that  change  color ,  such  as  the  squid   and  Octopus ,   Chameleon  do    not   modify  their  hues   by  accumulating   or   dispersing    pigments   within  their   skin  cells.
 Instead    the  lizards     rely  on    structural   changes    that   affect  how  light  reflects  off  their  skin Researchers  found  that   chameleons    have  two  super  posed  thick  layers   of  iridophores  cells ,that  have   pigment  and  reflect  light 
 The      iridophores   cells   contain   nano crystals   of  different  sizes  , shape  and  organizations,  key  to  the  Chameleons'   dramatic  color  shifts,  according to    researchers.The  Chameleon  change   the   structural  arrangement   of  the  cells  by   relaxing  or   exiting  the    skin,  which  leads  to  a  change  in  color.
