It doesn't need the surprise but it would help of course. Though Deviljho is still an endurance hunter.

Yeah, they could pretend to be some sharp rocks or whatever you think Ukanlos would disguise itself but how many monsters come near them? In the Battleground/Lava Canyon and the Snowy Mountain Peak/Polar Zone aren't many monster seen. Don't know where Akantor lives in Minegard originally (as it got trapped in the Battleground) so I don't know how he would react in his original place but probably not very differently as the Lava Canyon is his original environment and he doesn't react differently at all. And I never saw them doing that.

Another proof that your theory is wrong is Akantor's Ecology Video. While Gravios was slowly walking around Akantor openly showed himself and attacked him. Gravios didn't search the fight Akantor did. The same should work for Ukanlos

I don't deny they could do that but most of the times they wouldn't do ambush hunts.
