Cuttlefish Use Invisible Light Patterns to Flirt

Scientists have discovered that cuttlefish, which are like squids and octopuses, use special light patterns to attract mates.

These patterns are made of light waves that humans can't see because our eyes can't detect the direction the waves are moving.

The cuttlefish create these patterns by changing the color of their skin and using special cells that reflect light in a certain way.

This helps them stand out to other cuttlefish, especially during mating.

The study shows how different animals use unique ways to communicate and attract partners, which helps us learn more about how animals have evolved over time.
