And yes, fascinating creatures all. I wish they made good aquarium pets, but cephalopods are one of those creatures that one keeps just to prove they can; they don’t live long enough to really enjoy and are hard to find suppliers for.
I think the best summation I read of them was several years ago, when a scientist observed that they were probably the closest we’re going to get to genuine extraterrestrial life until we encounter the real thing, because they (at least octopuses) are fairly intelligent, yet so DIFFERENT from us.

In case you gents have missed this book, you might be interested in reading John Steinbeck’s “Sweet Thursday.” The main character, Doc, is a marine biologist, modeled on Steinbeck’s very close friend, Doc Ricketts. His grail was to write a paper on octopi. Very intelligent creatures, very moody, very emotional animals. Kind of like Doc himself!
