Vocalization

H. cavitympanum is the only known species of frog to vocalize at only an ultrasonic level.[2] The frogs have eardrums recessed in the side of the skull, with an ear canal similar to mammals' anatomy. It appears to have evolved this higher pitch (more than 20 kHz) frequency of communication to circumvent the background noise of its waterfall habitat.

gollark: No, don't do that.
gollark: `while true do xpcall(loop) end`
gollark: `adduser` or whatever it is lets you only allow specific people access to the computer and screen and whatever, which... kind of obsoletes passwords?
gollark: With `adduser` or something.
