Octopuses are fascinating sea creatures known for their remarkable problem-solving and escape abilities. Scientists have linked their problem-solving skills and adaptability to their highly developed nervous systems, which include a centralized brain and a complex network of neurons distributed throughout their arms.

Researchers from the Okinawa Institute of Science and Technology (OIST) and the University of Washington observed that octopuses exhibit two sleep stages, a quiet and an active stage, similar to REM sleep in mammals.
