Elephant seal flippers
While on the beach with these guys, I spent a fair amount of time at the longest range of my zoom trying to work for some intimate portraits. Mostly I was focused on the faces of the old males and their wonderful big nose and textured chest shields. However, their flippers have always intrigued me as well.
They have five fingers within their flipper and each ends in a tiny little "flipper-nail" (for lack of a better term). While at first glance it seems to beg the question of why they would still evolutionarily need nails at the end, it does appear that they are good for scratching an itch upon occasion (although, one would think there might be a better reason as well).
It's really interesting to watch them use their flipper, as you can see that their bone structure really must be similar to ours, where there are multiple knuckles in their "fingers".
