If you're not okay with maggots, you're not going to be okay with this video. As you can see from the still picture, the maggots are literally swarming over every inch of their prey. It's covered in as many maggots as it is covered in hair. By the time they're done, that moose carcass is polished up nice and clean.
You know what would be terrible? If you tripped and fell onto that pile.
