LONDON: Octopuses move with a simple elegance, but they have no rhythm, according to new research.
Each of an octopus’s eight arms is soft, flexible and muscular, and acts like it has an infinite number of joints, said the study’s lead author, Guy Levy, a postdoctoral researcher of neurobiology at the Hebrew University of Jerusalem. But, until now, scientists have struggled to understand exactly how these marine animals coordinate their complex crawling movements.
To learn more about these brainy creatures’ locomotion, the researchers watched videos, frame by frame, of octopuses crawling around water-filled tanks.
