|Silk worms of course also have silk (as does other worms). Now, it's a stupid question, but is this trait a seperate evolution path from spiders? I would think so.|
Interesting, but here we call the tarantulas "baboon spiders". All in all, we have 3 dangerous spiders here, the worst being a light (beige) little spider with a dark mouth area and dark feet tips. Called a "Sakspinnekop".
There is also a very interesting spider called a "Roman". Red hunting spider. I read somewhere that they are closer related to scorpians than other spiders. It's mouth is totally different from other spiders and it has no venom. It will however kill a scorpian in "combat". They also have the habit of running from shade area to shade area, thus creating the impression they are chasing humans (running after moving shade). Girls don't like them
(Sorry, I'm not used to this format yet . . . .)
Spiders actually have several different silks that they produce/ The silk for webs is different than that used for eggsacs or molting carpets, for instance. And they all formed independently.
Yes, Baboon spiders is how tarantulas are referred to in Africa. In South America, they're Bird-eating spiders. (No, they don't really eat birds -- or baboons). The African tarantulas are lots more aggressive (but not any more venomous) than other tarantulas.
Your "Red Roman" sounds like a solfugid, or "sun spider". They're not really spiders. They're not really dangerous, either, although they certainly LOOK mean. ;>
Also, it is a common misconception that tarantulas are dangerous. They're not. There is no record anywhere of any human being that was killed by the toxic effects of tarantula venom (although some people have been killed because they are allergic to it, like bee stings).
I've kept a dozen species of tarantula over the years (currently a Mexican redleg, _Brachypelma smithi_), and have been bitten a couple times. Feels like two or three hornet stings. (I've also been stung by a couple different scorpions, and even managed to get nailed by a South American centipede once --- THAT hurt). I used to breed black widow spiders, and was always rather careful around them.
I wrote a book a few years back on keeping tarantulas as pets. :>
