Anatomical terminology

In humans, it is a small tubercle on the visible part of the ear; the pinna. The antitragus is located just above the earlobe and points anteriorly. It is separated from the tragus by the intertragic notch.

The antitragicus muscle, an intrinsic muscle of the ear, arises from the outer part of the antitragus.[1][2]

The antitragus can be much larger in some other species, most notably bats.

gollark: Slightly relatedly, Kindles are really insecure (with everything running as root) and can be jailbroken for full root access. There are some cool slightly useful unofficial kindle applications around.
gollark: The thing with *that* is that you can't encrypt them such that you can only view them on a Kindle and not copy them or whatever.
gollark: No, I mean, Amazon can't lock them to only be readable but not copyable by users. Very practically.
