Colorfully Camouflaging Cuttlefish Are Colorblind

Cuttlefish are remarkable for their ability to camouflage despite being colorblind. Scientists have long debated how they achieve this, with early studies showing they have only one visual pigment. Recent research has tested their camouflage on various patterns, confirming their colorblindness. Theories suggest they might see with their skin or use chromatic aberration to discern colors. However, these theories remain unproven, especially regarding their ability to camouflage at night. The mystery of how cuttlefish achieve such effective camouflage continues to intrigue scientists.
