Researchers have made significant progress in understanding the complex camouflage ability of cuttlefish, despite this marine organism being color blind. These marine creatures can quickly change their skin patterns and integrate with the surrounding environment. The latest research presented at the 2023 Neuroscience Society conference involves examining the skin cells of cuttlefish, tracking brain activity, and observing their dreaming patterns.

The squid has the large head of an invertebrate, which has sparked interest in its complex behavior and camouflage ability. They can instantly change the color and texture of the skin, with speed and accuracy even surpassing chameleons. This phenomenon is closely related to their brain activity, prompting scientists to further explore - they use a 3D printed hat filled with sensors to achieve this goal.


The high-resolution video of squid skin cells reveals how brain output is reflected in their skin patterns. Their skin contains millions of pigment cells, which carry pigments and change shape and color according to muscle contraction. This mechanism allows the squid to quickly adjust its appearance.


Researchers also found that cuttlefish do not rely on fixed camouflage strategies, but adapt to the environment through repeated experiments. This behavior indicates that the squid has strong adaptability and learning ability.


The next step involves genetic manipulation to better understand the brain function of cuttlefish. Despite the challenges faced by squid gene editing technology, progress is currently being made. The ultimate goal is to insert genes that produce fluorescent proteins and light up neurons during brain activity.


In addition, innovative tools are being developed, such as a water tank surrounded by electronic ink screens. These screens are similar to e-readers and can simulate controlled environments without causing squid to lose direction due to strong light. This technology is crucial for studying gene edited squid and its neural patterns.


The ongoing research on the camouflage and neural activity of cuttlefish can provide new insights into neural plasticity and adaptability. Understanding these mechanisms may drive advances in bio inspired design and technology, potentially impacting fields such as robotics and adaptive materials.
