> I don't think you can claim that giant squid are avoiding humans: rather our respective habitats simply don't overlap enough to have noticed them until we could build vehicles capable of exploring where they are found.
Well, we've got documented reports going back continuously to the ancient Greeks of giant squid, and photographic evidence going back almost as far as common photography. So, its not so more that we needed "vehicles capable of exploring where they are found" to substantiate them as we needed photography, etc., for people other than those who directly encountered them to be able to clearly distinguish the real reports of giant squid from all the rumors of fantastic beasts that lack such evidence.
