Answers to Tarantula Questions

Yesterday we featured a book about tarantulas and asked some questions about them, Today we have the answers to those questions, using the illustration.

1. Find the legs and count them. Are there eight legs?

Yes, tarantulas have eight legs like other spiders and arachnids.

2. What are those two appendages in front of the tarantula?

Those two shorter appendages at the front of the tarantula are not legs. They are called pedipalps. They are used for various purposes other than walking.

3. Can you find the eyes? Do you know how many eyes a tarantula has? Is this more than, less than or the same number as other spiders?

Tarantulas have eight small eyes. That is the same number as most spiders. One exception is the brown recluse, which has only six eyes.

4. Where are the spinnerets to make silk?

Tarantulas have spinnerets at the back of the abdomen. In this photograph they only show as a slight bump. Both males and females make silk. They use it to line their burrows. Tarantulas do not make elaborate webs.

5. Is this a male or female spider? How can you tell?

Based on the fact this spider was found out wandering around and that it has extensive black coloring on its legs and abdomen, it is reasonable to assume it is a male.

Mature male tarantulas have a hook on the tibia of the front leg, which is not visible in the photograph.

How did you do? Are you a tarantula expert?

Be sure to let me know if you have any other questions about tarantulas.

    hi I have a mexian red rump and I think it is a female she has a leg span of about 3-5cm
    It looks to me as if she is getting ready to molt as her abdomen is a brownish colour and her legs are black but getting a white to grey colour to them and she is not eating
    I’ve noticed that she is behaving very strangely as she is regularly leaning towards her right side and rubbing her left legs on one other as well as on the left side of her abdomen and this will cary on for quite some time then she would proseed to lean towards her left side and do exactly the same thing with her right legs
    my question is, IS THIS NORMAL? i have asked all my friends that own a tarantula/tarantulas and non has ever heard or seen something like this
    can you please help me as I am clueless and very concerned about her wellbeing

    Danie,

    How long has it been since your tarantula molted last? If it has been a long time, that is probably what is going on. I would back off and leave her alone and see if that happens.

    If you have never seen a molt, the tarantula usually lays down some extra silk. Then it may actually flip over on its back and lay there. Don’t freak out, because that is normal. Give her some time alone if that happens.

    Also, when tarantulas are nervous, they kick the hairs off the back of their abdomen. Is the back of the abdomen starting to look bald? If so, then try to give her plenty of quiet time.

    Good luck!

    hi roberta
    I’ve gotten her in Jan and she’s molted once since then but i did not see her molt as i was asleep when it happened
    i have a friend with 13 T’s and he has never seen this behaviour in one of his
    do you think its just normal grooming behaviour or is she trying to loosen her old skin? as she is showing the same behaviour now as when she molted the first time since i got her
