Sepia mestus (the reaper cuttlefish) ejects water from the mantle which allows it to move through the environment using jet propulsion.
Sepia mestus, also known as the reaper cuttlefish or red cuttlefish, is a species of cuttlefish native to the southwestern Pacific Ocean, specifically Escape Reef off Queensland () to Murrays Beach off Jervis Bay (). The animal ejects water from the mantle via a tubular funnel. This technique allows the animal to move through the environment using jet propulsion.
