Giant squids have lungs, but not the way you
and I have lungs. The squids live in the ocean,
and do not come to the surface for air, so they
must get the oxygen they need from another way.
Fishes, octopi, squids, and non-mammal animals
all use gills. The gills are similar to our
lungs in the idea that they take oxygen from
what is brought to it. So in our lungs, we
breathe in air, and in this air, we have some
oxygen. When these oxygen molecules come into
contact with our lung surface, they are
transported into our cardiovascular system
(heart, arteries, and veins) so that all of our
organs can get oxygen, and stay alive. Gills use
the ocean water. The animal (like a squid) pumps
(or breathes) water to the gills, and when
oxygen in the water touches the gills, it is
transported into their cardiovascular system
(heart, arteries, and veins). Their heart system
then pumps the blood through their body, and
keeps the squid alive. You can see their outlet
(siphon) above their eyes on the posterior side
of the mantle (opposite the pointy side).
I hope this helps!
Squids do not have lungs. Lungs do not
really work under water. They have gills.
Squid bodies are covered with a mantle, which
is sort of like a tube sock. The gills are
hidden inside the mantle. If you look at a
picture of a squid, you can see that the mantle
starts right behind the eye. That would be the
open end of the mantle. They can open it up to
let water go in.
All squids, giant ones and small ones, have
bodies that are like this.

the sea, you may want to be a marine biologist
