Jet Propulsion in Fish Predates Modern Tech

The article explains that jet propulsion is not new and has long existed in fish species like cuttlefish. Fish move by expelling water through gill slits, positioned for maximum thrust, while tails and fins stay mostly still. If wrong direction is needed, the fish reverse by drawing water in and expelling it from the mouth.
