Very Large
One good thing to note is that the giant squid is the biggest of all known squid species. Where do they stay and why are they so rarely seen? Well, these squids mostly reside in very deep cold water. Hence they do not really come out of the deeper levels of the sea. Since scientists cannot go too deep under the water due to the temperature and pressure, these squids have remained a big mystery and very little is known till date about them. However, giant squid spottings have been reported all over the world.
