How to tell an anteater from an aardvark.

Parallel evolution is a curious thing, but these two (unrelated but very similar) creatures do have some distinguishing characteristics.  Most obviously and notably, the anteater has a streamlined, narrow head, curving smoothly to a very long, pointed snout.  They also have small ears.

The aardvark has much longer, sort of donkey-looking ears, and its face ends in a very pig-like large-nostriled blunt snout.

Cerebus was an aardvark, not an anteater.  Arthur is just a mess.  The blue aardvark in the Ant and the Aardvark was in fact a (poorly drawn) aardvark, so kudos to them.  Cardiff's famous anteater is an anteater.  And none of them are wombats, who have nothing to do with ants in general but are frankly much cuter.
