Wildlife Spotting

I can't narrow this down to species level, but from what I can see I would feel confident getting it to the genus Dolomedes, the fishing spiders. Whenever you spot something that's FROM an animal (such as feces, tracks, a web, a nest, etc.), it can go in the category for that animal. Since this belongs to a spider, I've gone ahead and have moved it to Arthropods for you. You've already got it placed in the "Signs of Wildlife" mission so that's great. It's a perfect mission for this type of spotting. Great work!
