It's hard to tell if the Tigmadars' noses are accurate, because most fauna of its lineage don't show noses except from the side, where it's impossible to tell if they have a philtrum. For the Tigmow, I assumed its ancestor didn't have a philtrum, and didn't add one. Hydromancerx's Marine Tamow descendants/grand-descendants don't seem to have philtrums, either. It seems philtrums may have something to do with carrying smells to a vomeronasal organ in the mouth, so it could depend on how need the fauna would have for a vomeronasal organ, if they have one at all.
