Key Highlights
•
Scientists have discovered that iridosomes, the specialized organelles responsible for creating shimmering guanine crystals in animals like fish and chameleons, actually originate from lysosome-related organelles. This finding reveals a surprising cellular pathway for building these biological mirrors, which are crucial for animal coloration, communication, and vision.
