What?? A "full split?"
In this picture your fingers do appear appear relatively large in proportion to your palm. However, that has nothing to do with your question.
Well, it does look like your thumb extends quite a bit, like there is some laxity in the CMC joint. The thumb itself in the IP joint isn't overly extended, but your metacarpal is exceptionally straight in this pic. You can see it poking into the fat pad there on the lateral side of the hand.
Interesting. But that's just my hand folding a bit, not poking into the pad.
But when I was comparing my hand to yours, mine has a lot more "webbing" in between the index finger & thumb. I'm not flipper or anything, but mine is obviously stretched when I have my thumb fully extended and yours doesn't appear to be like that.
If you call a "full split" a straight line from pinkie to thumb, then no, that's not unique - I can do that, too (I actually got that "skill" from doing finger speed drills for piano lessons)Make a straight line from pinkie to thumb.

So I can make the L between my thumb and index finger bigger than average?
