The Amazing World of Animal Color Changing

The video explores the fascinating ability of certain organisms to change colors, primarily for camouflage, signaling, and survival. It explains the role of pigment-containing cells called biochromes and chromatophores in this process. The video highlights species like chameleons, octopuses, and squids, detailing how they use chromatophores to adapt to their environment. Chameleons, in particular, have multiple layers of chromatophores, allowing them to change colors based on temperature, mood, and environmental stimuli. The video concludes by emphasizing the importance of light and pigments in color changing.
