Claim: Sepia mestus (the reaper cuttlefish) ejects water from the mantle which allows it to move through the environment using jet propulsion.
Evidence: 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.
