Struth! Walter.  Fair dinkum mate, you're enough to make a bloke wish human
cloning was available and legal.   :-)  You wrote:

They may not be strictly parabolic, but they are obviously very efficient
and directional sound gatherers and reflectors:  I refer to animal ears.
Note the way a dog pricks his ears and turns his head to pick up the sound
he wants; how a horse (or a kangaroo) will swivel their ears for the same
purpose.  And to very good effect too, if you consider how alert wild
animals can be to the slightest sound.

Of course being small they can't possibly amplify low frequency sounds, can
they?  :-)  (Elephant ears - the external flaps - are for a different
purpose altogether, I think.)

Now if only we could clone Walter and Klas  and put them together with a
really good lab. and research grant, think what we might learn about both
animal hearing and the design of sound gathering reflectors.
