Octopus to fool prey by directing them towards the mouth, making them one of the few bioluminescent octopuses. Octopuses mainly move about by relatively slow crawling, with some swimming in a head-first position. Jet propulsion, or backwards swimming, is their fastest means of locomotion, followed by swimming and crawling. When in no hurry, they usually crawl on either solid or soft surfaces. Several arms are extended forwards, some of the suckers adhere to the substrate and the animal hauls itself forwards with its powerful arm muscles, while other arms may push rather than pull. As progress is made, other arms move
Propulsion system is also important, as is the interaction between locomotion and muscle physiology, in determining how the structures and effectors of locomotion enable or limit animal movement. Propulsion Propulsion means to push forward or drive an object forward . The term is derived from two Latin words: "pro", meaning" before" or "forward"; and "pellere", meaning "to drive". A propulsion system consists of a source of mechanical power, and a "propulsor" (means of converting this power into propulsive force). A technological system uses an engine or motor as the power source (commonly called a powerplant), and wheels and axles, propellers, or
