There's a lot to be said about thumbless squirrels on the web. One site was a personal reflection of a squirrel owner who stated their family squirrel has opposable thumbs. Must sites I scanned stated that squirrels don't have opposable thumbs, but do exercise flexibility with their fingers.

I learned that opposums do have opposable thumb.

One site had a declaration that--get ready!--elephants have opposable thumbs. The things you read on the Web!

I'd say the jury's out on this one, with most witnesses stating that squirrels don't have opposable thumbs. I don't have any idea where that elephant comment came from!

P.S. Oh, one definition of the opposable thumb was that it could be identified by the owner's ability to move it across the palm. Never saw an elephant do that!
