I second this.
1) The segments in a tarantula's 'broken' leg do not contract - if the leg was completely removed, the sphincter contracts.
2) Tarantula blood is called haemolymph.
3) I've seen tarantulas with 'broken' legs (where haemolymph was leaking from a joint or segment) that did not remove the leg. More times than not, actually.
4) Tarantulas don't 'writhe in pain'. There is no possible way we can confirm that the tarantula is in pain. All scientific evidence thus far indicates they do not feel pain - their nervous system is simply too basic.
Please stop spewing all this nonsense, unless you have photographic or video evidence to the contrary.
Coaster - maybe you should spend a little more time in the hobby before making such outrageous claims as to what tarantulas can and can't do. It might benefit you to do some more research as well.
EDIT: I just read the latest few posts regarding aliens...:wall:
I agree with Shelley and Rosie - I'm lost.
1) You're right: The Coxa-trochanta does. I was putting it into layman's terms. (In fact, this is where the research for body armor that will Tourniquet extremities comes from)
2) Blood has many names. Again, layman's terms. Your correction cited, yet Unnecessary.
3) As have I, yet I have also seen many cast them aside. Again.. Unnecessary attempt at correction.
4) Pain is a natural response. If you didn't have a pain threshold, you wouldn't survive very long, now would you? Perhaps not as advanced as a human's.. it is there.
Before you tell me to stop spewing nonsense, you yourself needs to review your facts. I like you XhedX, but this response is not very well thought.
