The octopus is a sea creature known for its unique anatomy, which has always made it a subject of query and interest. The sea creature is bilaterally symmetrical, with eight arms in total. The movement of an octopus is mysterious and exciting to observe. Scientists have been bewildered by the pattern and coordination of their crawling.
The soft body of an octopus can easily change its shape. When an octopus swims, its arms trail behind. But the most exciting part is the crawling of an octopus, which depicts the typical movements of sea creatures. Researchers say that octopuses make use of specific strategies to coordinate their limbs. Most bilaterally-symmetric sea creatures use similar techniques while moving forward, except for a few. Octopuses can, however, move in any direction with turning their bodies.
Watch the video depicting the movement of an octopus to understand its locomotive patterns. The octopus simply uses any of its arms to propel forward in that particular direction. The other arms push the body in that direction without moving or turning itself. It has to decide in which direction it has to move and choose the relevant arm to go that side. It shortens and elongates the arms while moving; creating a thrust that pushes it forward. However, there is no rhythm present in its body movement and coordination.
The movement of an octopus is a part of the Body and Dynamics model, which can be easily explained by this example. This flexible creature has a unique body structure and diverse body dynamics. In easier terms, the movement of an octopus is non-linear and elastic. An octopus can control its movement through its non-linear and complex body dynamics. As per researchers, the movements of an octopus are highly sophisticated and an excellent way to understand robotics.
