That's actually really interesting, given its size, because the ridges suggest a longer growth time and that would hint that it probably won't get too much bigger.
Teeth? Wasn't expecting that, but okay, that would make sense given the other attributes.
Even deserts have water if you go far enough up or far enough down, right? I mean camels only need to drink every six or so months and can take in more than 200 liters of water in a couple of minutes. They're incredibly efficient and your banthas wouldn't even need that much as it's so much smaller - you're googling camels now, aren't you?
Okay, I admit, it wasn't my best attempt! Still, if you've ever examined an elephant you'd understand the verbiage was entirely accurate, if clumsy.
