Deviljho is more meant to be a endurance hunter than an ambush predator. Deviljho isn't the fastest monster but a monster with great endurance and persistence. So it would clearly make more sense to hunt a Popo/Aptonoth/Zuwaroposu till it is exhausted and kill it then.

I don't know about the other two (as we don't have any reference for such big monsters) how they could do that. But seriously... where should those two hide? Of course they could attack prey from beneath but which prey wouldn't get the quakes and instinctively run away? No, they're clearly not made for ambush hunting.
