Meet the cuttlefish — nature’s aquatic artists. These marine brutes belong to the cephalopod family, including octopuses and squids. What makes them stand out? Their skin can change colors in seconds, blending into coral reefs or flashing warnings to rivals.

As unique ocean creatures, they use this superpower not just to hide but to communicate, quest, and indeed trick bloodsuckers. Their smarts compete with those of some mammals, working mysteries and flashing back assignments. From their delicate cuttlebones to their lightning-fast revulsions, cuttlefish data reveal a species where biology meets brilliance.  https://fishesinfo.com
