    Ah i guess so.
    Albeit dont red back spiders become prey to white tails every so often?

    Yes, they are not impervious to predation themselves. They're just very good at capturing things that walk along the ground.

    I have seen a video where a theridiid captures a tarantula in a web at ground level, but the tarantula manages to catch the theridiid with it's leg and promptly kill it. And there was another in which the same thing happened to an orb weaver (but the tarantula in that case was probably put there by a human).

    Yeah the thing is, tarantulas arent really as capable as active hunting true spiders, at the same size that is.

    They are both slower, less agile and have sort of akward fangs placement for that size.

    So is a tarantulas's only possible advantage its size? If it doesn't have the web-making abilities of other spiders, nor their agility or speed of some spiders, what advantages does it have?

    Size and bulk of course, tarantulas are huge.

    Aside from their size?

    Nnno, not really.

    To be fair, a lot of them do have 'abilities' like urticating hairs that other spiders don't have.

    Which is only useful against non arthropod attackers.

    I'm not trying to argue that they have superiority against other arthropods, but that they have superiority in some areas that give them a competitive advantage, so in this case they have superior defences against non-arthropod attackers.

    Scytodes eat theridiidae..... Scytodes longipes and thoracica can wipe out populations of steatoda...parasteatoda and latrodectus

    They also do prey on Loxosceles spiders too.

    there are tons of predators of widows. many spider wasps will simply pluck the web and lure them out

    Mimetidae sp. are predators of Theridiidae..... "Pirate" spiders.

    They are nasty, saw one eating a false widow not too long ago.

    And I saw a Parasteatoda eating an Agelenid.... Ciiiiircle of liiiiiiife!

    But seriously, I don't think they're nasty! Pirate spiders are fascinating! I saw a beautiful one last summer.... I'll try to dig up pics. I think it was M. puritanus?

    Well they do leave a mess after eating.
    And my room is full of them
