I'm sure i found Sand Stalker on Driftwood too, i'll see if i can find it again and get a screen shot
(i think the same location too near the crates)
EDIT: So far no luck lol
There was some good pictures of some bosses on another thread too a while ago when the bosses first came out, included a rock crab boss called Man Ripper i believe - have not yet found it. I also found a swamp alligator boss which i shall find again and take a screenshot of (Cuba).
It was at the end of this thread (ty to Jack):
