Here are two nouns to be compared before (chipmunks) and after (most other ground squirrels) ‘like’.

Since chipmunks and most other ground squirrels

are similar, it is a better idea to list them as “similars” (noun + noun) and not “different” (noun = noun).

As for Chipmunks, they are

also the same (plural noun) and so are eek of muck.
