The function of the water jet is to move the squid from left to right for example if the squid shots water left it will move to the right and vice versa
It filters the waste of the squid waste and it also separates the water and blood of the squid.
Squid move by jet propulsion, using its lips to suck water in then squirts it out its bottom.
The pen is a feather-shaped internal structure that supports the squid's mantle and serves as a site for muscle attachment. It is made of a chitin-like substance. It is the remnant of the squid's shell, so it is a vestigial structure.

Newton's 3rd law says that the second object exerts an equal and opposite force on the first. The squid lets loose a stream of fluid which exerts an equal force on the squid and the water. So the fluid from the squid pushed against the water, but also the squid. So the squid gets propelled through the water.
Yes, squid swim head first. They have a water jet and if the water jet shoots out water, it'll propel the squid, head first, throughout the water.
The squid sucks up water a tube called the siphon, then shoots it out to provide locomotion by jet propulsion.
It filters the waste of the squid waste and it also separates the water and blood of the squid.
The squid has a muscular mantle (outer covering) which, when expanded, fills with water. When these muscles contract, water is expelled through a single siphon and the squid is propelled in the opposite direction. The squid can control its direction by rotating (moving) the siphon.
The opposite direction of the water it moved.

Squid move by jet propulsion, using its lips to suck water in then squirts it out its bottom.
Waste exits a squid by being transported through the anus and out of the siphon.
Air intake from water
for self defence and for projection through the water
They take in water and shoot it out behind them like a jet.
Squid are phylum mollusca. They are marine cephalopods and are part of the invertebrate family. Ocean dwelling mollusks move or swim by jet propulsion. They propel themselves by ejecting water from their body. The squid ejects water from a cavity within its body.
