This escape route is used when the predator doesn't respond well to visual warnings. In this case, the cuttlefish will use their jet-propulsion and ink jets to escape (Cuthill). Jet propulsion occurs when the cuttlefish sucks water into its mantle cavity and then uses its muscles to forcefully push out the water, causing the cuttlefish to accelerate in the opposite direction. Water exits through the funnel, which can move to control the angle of the spray of water ("NOVA," 2007). Simultaneously, the cuttlefish will eject its ink in one of two ways. In the first way it creates a smoke screen of black ink that allows the cuttlefish to escape. In the second way, the ink is released as bubbles that are surrounded by mucus that resembles the cuttlefish shape and size. These ink bubbles essentially act as a decoy, allowing the real cuttlefish to escape ("NOVA," 2007).
