Trying to work out the biology of Oddworld's creatures from the games is like learning about animals by visiting zoos, ie, not very useful.
As for the meech, that's like studying a T-Rex from a small, blurry photograph of a partial skeleton.
However,
somewhere there is a single, full-body sketch, clearly depicting a four-way , beak-like mandible, and unusually posed bipedal legs. They sure
look mean, but then so do
stargazers.
There is little we can reliably say about the lifestyle of the Mudosian meech,
Tretramandibi mudosus, but in a fight they would certainly be a badass contender, perhaps a match for a scrab, and definitely more than a paramite can handle. Though as we all know, the paramites we know (
Paramitus paramitus) strictly hunt in packs, and a well coordinated assault by a multitude of fanged pedipalps are likely to overcome even the hardiest Mug (sorry Max). Scrabs (
Scrabanicus tyranni), as we all know, are formidable, I don't think there is any creature that isn't at least twice it's size that can withstand the alpha male's Shred Power.
But then, we don't actually know how large meeches could get, and the large, mysterious skeletons that litter Mudos' wilderness haven't escaped anybody's notice.
