This is a very good question. Squids move through the water at high speeds using a jet propulsion-like organ called a "siphon". What the siphon does is take in water and thrust it out, much like a jet engine. The end result is the jet-like streamline of a squid.
The water jet is a means of propulsion.
they jet through the water at really high speed
Squids move through the water by jet propulsion. They draw water into their mantle cavity and then forcefully eject it out through a siphon, creating a powerful jet of water that propels them forward. By controlling the direction and force of the water jet, squids can move in different directions and at varying speeds.
The colossal squid moves by using its fins and jet propulsion. It can swim forward quickly by expelling water through a funnel-like structure to propel itself. The fins help with steering and stabilization as it moves through the water.
Octopuses and squids can also move by using a form of jet propulsion. Water is drawn into the mantle cavity and then forced out through a tube, propelling the cephalopods backwards from danger. In addition, squids and octopuses produce a dark-colored ink when the are frightened. As this ink is released into the water, it helps to hide the mollusks/squids/octopuses and confuse its predators
Bivalves move by using a blade shaped muscular foot.

The squid sucks up water a tube called the siphon, then shoots it out to provide locomotion by jet propulsion.
They use jet propulsion, expelling water from inside their bodies out through an orifice in between their tentacles. It may be the beak, I don't know. They also make some motion by swinging their tentacles, but very little. It is the same way Nautiluses and Octopi move.
Jet Propulsion Laboratory was created in 1930.
yes they do because they are related to the octopus and if you look at david atunburrah documantaries about the sea you will well see by dakoda
A siphon enables the animal to squirt water, and move quickly by jet propulsion. Squids do this if they need a quick burst of speed, to grab prey or escape, and scallops use it to swim up and around, for example (look it up on YouTube, it looks really nonsensical!).
