Can't stop thinking about muntjac deer. See the thing with muntjacs is that they have these large scent glands below the eyes and on the forehead, and they use them to mark territory. Many types of deer have the glands in front of the eyes (pre-orbital) but muntjac are unique in having forehead glands (frontal). Here's the video I saw. There's something really unsettling about the idea of an animal being able to like. Open it's face. Idk I think it's madly creepy but it's like a perfectly natural thing for the animal to do. It just looks scary.
