Spotting

Hello. I moved this to Arthropods. "Other" is often and perhaps understandably interpreted to mean "unknown" or it is used for something that isn't quite an animal but came from an animal, a "sign of wildlife". A sign of wildlife always belongs in the category of the organism that produced (or is pointed at by) the sign. So a snake skin belongs to reptiles, an elk track to mammals, an insect egg mass to arthropods, a nest to the group of the animal that built it, and so on. In general terms, the thing to remember is that "other" is concerned with categories. So if it's not (from) a bird, amphibian, fungus, or one of the other categories, then in belongs in "other". An example would be a worm or a starfish :-)

Eek, I have no idea what made that but it's pretty impressive.
