Phylloderma stenops: Here's a bat with a horseshoe beneath its nostrils that's bigger than the noseleaf.

Tonatia silvicola: Big-eared, bigger eared. This one is weird in that when you touch the crown of its head, it curls its ears back like ram's horns. No other bat does that. Why this one does isn't known.

Trachops cirrhosus:You've heard of this bat, though I doubt you've seen it. It is the famous frog-eating bat. It has these weird papillae on its chin and lips, also function unknown. It finds frogs by passive listening instead of by using its echolocating ability. It uses a "hang and wait" strategy until it hears a frog sing or hears a frog move in the water, then it pounces on that spot.

Centurio senex: If you can get the perspective here, actually this is the head of the bat. Here's the right ear, left ear, and the nostrils are down here. And there are all these wrinkles and flaps covering its face. If it had its chin up, you could see that it has canals that go from its nostrils down to its mouth. I wonder if it's drooling some substance into its mouth. Another big unknown.
