They get up to 27 lbs. BTW - they also travel in packs. I was on an Army exercise 8-9 years ago and was laying in the woods as part of an ambush. I heard a huge amount of rustling getting closer and closer and next I knew a pack of coati ran me over. This was the first time I'd seen live ones.
I suppose there are those that eat them just like some folks eat coons, groundhogs, etc. I don't how much the fur is worth but I know that folks used to trap them..
