Your list seems completely normal to me, except for the alligator and squirrel, just don't find them around here.
A few of the more unusual things I have had (at least from an American's perspective)
Sea urchin roe (but any sushi aficianado will tell you it fabulous, and I agree, it is one of my favorites...too bad it is so expensive).
Chicken feet - dim sum staple. I am working with an aircraft maintenance company in Hong Kong, because of me, they affectionately refer to them as "landing gear".
Durian. Oniony, floral, pudding.
Lamb brains. Fresh, sliced, with a squeeze of lemon. Mmmmm.
Jellyfish salad. Crunchy, saline, good vehicle for other flavors.
To name a few.
