It draws water into its mantle cavity by expanding its muscles. The mantle stretches like a rubber band, then contracts and forcibly pushes the water out through the funnel. The squid shoots backward, tail first.
The squid sucks up water a tube called the siphon, then shoots it out to provide locomotion by jet propulsion.
Squid do not have "legs", but they do have appendages that act in a way for locomotion. They have ten total appendages, 8 arms and 2 tentacles.
Siphons can be used as a form of locomotion. Water goes into the siphon and shoots out and acts as a form of jet propulsion, directing the squid in the way it wants to go.
Squid arms are used for capturing and manipulating prey, as well as for locomotion. They are equipped with suction cups for grasping objects and are essential for the squid's ability to swim, catch food, and defend itself from predators.
The water jet of a squid is used for locomotion, allowing the squid to move quickly through the water by forcefully expelling water from its siphon. This jet propulsion mechanism is essential for squid to catch prey, escape predators, and navigate their environment efficiently.

Squid use their suction cups for grasping onto and manipulating prey, helping them catch food more effectively. They also use the suction cups for locomotion and maintaining their position in the water.
The squid mantle is a muscular, fleshy covering that encases the squid's internal organs. It plays a crucial role in locomotion by contracting and expelling water through the siphon, allowing the squid to propel itself rapidly through the water. Additionally, the mantle houses important structures such as the gills and contributes to the squid's ability to regulate buoyancy. Overall, it is essential for both movement and protection of vital organs.
A squid's pen is a stiff, flexible structure made of chitin that runs along its body to provide support and help maintain its shape. It also acts as a site for muscle attachment, aiding in movement and locomotion. Additionally, the pen provides protection for the squid's internal organs.
A squid's tentacles serve multiple functions, primarily for grasping and capturing prey. They are equipped with suckers that help hold onto slippery animals, allowing the squid to secure its food. Additionally, these tentacles aid in locomotion and can play a role in mating behaviors by transferring sperm to a partner. Overall, the tentacles are essential tools for the squid's survival and reproduction.
Squid use a kind of jet power. Water is squirted at great pressure out of a nozzle on the squid's body. At times the squid can swim so fast that it may pop out of the water and glide through the air at 25 to 40 miles per hour. A squid may fly for 100 feet or more before it splashes back into the water.
Water can easily pass into the cavity of a squid through its siphon, a specialized structure used for locomotion and respiration. When a squid contracts its muscles, it expels water through the siphon, and when it relaxes, water is drawn in, allowing for efficient gas exchange and movement. The flexible and muscular nature of the siphon enables quick adjustments, facilitating the rapid intake of water when needed.
