The giant nose being a sign of health is sorta funny, but also affecting the calls made is interesting. I know this isn't the case, but I think it would be funny if the giant noses weighed down these swimming monkeys. Ruminating is a bit gross, but then again rabbits eat literal feces. Crocodiles not being able to hear these monkeys is so cool. The eyes being similar to gobies/mud skippers is silly. Being aggressive and using kissing behaviors is silly too. The needle teeth is a bit scary.
