Cuttlefish camouflage patterns are more complex and flexible than previously thought, according to a study published in Nature. Researchers used high-resolution video and machine learning to investigate the camouflage and blanching responses of cuttlefish. The study revealed that cuttlefish have a wider range of pattern components and a more intricate camouflaging process than previously believed. Cuttlefish are known for their fascinating abilities, including delayed gratification, episodic memory, and intelligence. The skin of cuttlefish contains chromatophores, iridophores, and leucophores, which work together to generate their unique optical properties.

Humans have invisible skin patterns called Blaschko lines that trace the journeys our cells took as they divided and grew into the skin during embryonic development. These lines are drawn by the paths of keratinocytes and melanocytes. Mutations involving color-producing cells can lead to pigmentary mosaicism presenting as streaks and swirls following Blaschko lines. Another rare but extreme example of mosaicism in humans is chimerism. These lines can also help doctors diagnose skin conditions.
