lol, what are you talking about..?
HEM has an auto-rating feature that displays a small icon in your HUD. Based entirely on VPIP/PFR as far as I know. Rock for nits, fish for fishes, whale for whales, ... Eagle is for the laggish TAGs or taggish LAGs - 24/20 or something like that - i.e. pretty much the hardest opponents to play against (preflop at least).
The way to play them: if they're on your immediate left, stand up from the table unless there's also a huge whale at the table to make up for it. If they're on your right or front, it's not too much of a big deal. And if you can't avoid them, take some extra time to look at their game and try to figure out if they have postflop leaks you can exploit.
