"Erudition", i.e. accumulation of knowledge, is very much up QI Street and could be a good subject for an E show.
I will post a couple of ideas that can be all incorporated into GI Animals, I think.
We have all heard about such animal adjectives as "bovine", "canine", "volpine" etc.
But how about:
Eusuchian - belonging to an alligator
Alcelaphine - ..... to an antelope
Dasypodid - .... an armadillo
Mustelid - .... a skunk or a badger
Edetante - .... an aardvark
Macropodine - ... a kangaroo
Ranine - .... a frog
Lutrine (not "Latrine"!) - .... an otter
Monothremal - .... a platypus
Murine - ..... a rat
Anapsis - ..... a turtle
Batrachian - .... a toad
Vombatid (not so hard) -.... a wombat
