So after a ton of reading and researching, the general conclusion I’m seeing about arachnid intelligence is…all over the place.
Recently my G. rosea sling “Iskierka” managed to squeak out of an air-hole that was just a tiny bit big and go on “walk-about” in my office bedroom. I found her on the floor merrily tromping along toward a book case a good 10 feet from her starting point. (And In no hurry, she was just walking along.)
As an experiment, I placed her cage in a larger wide container, and placed a glass lid on her cage. (not exactly lightweight, but unanchored.)
She escaped the cage.
How? She isn’t more than 1/2″ in complete diameter and the lid is 1/8″ thick glass. She SLID the lid back enough to squeeze out. She then wandered slowly and in no hurry about the large container, checking here and there for who knows what. I re-caged her easily with a light tap on her rear leg and she waltzed into a small pill bottle. I put her back in her original home and she went back to her normal spot as if nothing had happened.
Now WHY should she want to? Or care? We keep these wee ones in tiny little cages no bigger than a large vial or deli cup at this point as it is supposed to be “big enough”. If these creatures ARE comfortable in this kind of an environment, WHY BOTHER with the Houdini act? -rhetorical.
Without anthropomorphizing, this tells me that even as a tiny sling, these animals can problem solve.
I have two larger T’s who are within 1/4″ in growth of each other, the same species…and couldn’t be more different personalities. In fact I keep falling back on my “cat” analogy. If you put eight legs on cats, I don’t see a whole hell of a lot of difference in behavior. (Granted cats are larger, and do some different things, but way too much is the same for me to just blow it off as imagination.)
These animals have moods.
They can determine that their owner isn’t a threat and allow itself to be picked up and handled as opposed to lunging/running or what one would assume to be an automatic flight/fight response.
Or they can be like OBT’s (Orange Bitey Things or their name:Pterinochilus murinus) and make the attack the primary modus operandi no matter what. (UNTIL the exception…there are always exceptions with T’s.)
Not saying “brain surgeons” here, but there is a whole hell of lot more going on in those prosomas (the front body part that contains the brain), and it doesn’t take a biologist/entomologist to figure THAT out.
They can barely “see” as vertebrates do…until you realize/discover that they have an overall sensory apparatus that would make Daredevil feel like a 2nd rate charlatan. (Their entire body is a sense organ in essence.)
I’m betting that these creatures can “SEE” better than we can, but in an alien way that combines all of this stuff into a coherent picture that we human types can’t really visualize…much the same way that multiple dimensions beyond the 4th one buggers up our poor ape brains.
And then I read over and over how little they have actually been studied, and the first thought that pops up in MY prosoma is…WHY THE HELL NOT? -heh.
Also Tarantula wikipedia entries need fixing…badly. (egads.) :-)
