Thank you for the great question.
Squid are very interesting! They have two
different ways of locomotion, or ways of moving
around. For moving slowly, squid use the fins
on the side of their body. More often, squid
use a form of jet propulsion to move around
Squids use the muscles along their mantle,
or the main part of their body, to draw in water.
The water is then forced out by other muscles
through the funnel, which is located near the
head. The squid points the funnel in the
opposite direction of where it wants to go and
then the force of the water pushes them there. In
this way, squid fly through the water in a way
not too unlike a jet plane flies through the air.
I have included a
picture that shows, in general, where the
water flows into the squid, and where it flows out
through the funnel.
