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.

As progress is made, other arms move
Sea Jet a few technologies that will be integrated into the Zumwalt-class destroyer. Notable among these is the return of the tumblehome hull design. Sea Jet Sea Jet, or Advanced Electric Ship Demonstrator (AESD), is a naval testbed funded by the U.S. Navy's Office of Naval Research. The vessel is operated out of the Carderock Division's Acoustic Research Detachment in Bayview, Idaho. "Sea Jet" was operated on Lake Pend Oreille, where she was used for test and demonstration of various technologies. Among the first technologies tested was an underwater discharge water jet from Rolls-Royce Naval Marine, Inc., called AWJ-21, a propulsion concept
