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
Jet Propulsion Laboratory Science Division life in and the nature and evolution of the universe. These are significant issues related to NASA's mission. Theoretical and experimental studies are conducted which lead to new missions. They are engaged in the development of new instrumentation and in the analysis of data, publishing new scientific knowledge, and in the communication of that knowledge to the general public. Not all science at the Jet Propulsion Laboratory is contained within the Science Division. Approximately 30% of JPL scientists are embedded in other divisions. JPL's charter is to conduct robotic space missions for NASA, to explore planetary systems, understand the origin
