Minecraft xbox 360 Biomes?

So i started playing minecraft again and i noticed they made an update with new structures. I found the desert temple but for some reason i can't even find a jungle for the forrest temple. Is there something wrong with my xbox? Also i can't find any "deep seas" for the undwerwater ones, i've been doing all this searching on creative so there's no way i'm missing them, i'm just missing the biomes.
