Defence and
Transportation
All
squid move through the ocean using a jet of water forced out of the body by a siphon. Giant squids are streamlined for speed,
and they propel themselves, often to great depth, by undulating the fins that run down the sides of their bodies. If danger
approaches, expelling a powerful jet of water produces more rapid movement. A further aid in avoiding predators is to release
ink into their jet stream, which acts as a "smoke screen” that congeals into a squid-like shape that holds the enemy's
attention while the squid turns pale and jets away.
Fun Fact: Did you know that a giant squid's eye can be as big as a 1 foot in diameter, thats
the size of a basketball !!!

Breathing And Respiratory
The water and oxygen enter
the squid's body through the mantle. The respiratory exchange between the carbon dioxide and the oxygen occurs
in the gills. The oxygen is then carried through the tissues by the blood and the carbon dioxide and the water
are expelled from the body through the siphon.
