Zoologist is just studying, skin deep is just skinning, but if u wanna 100% the animal in the compendium then u should track. I don't think it's needed for those achievements though :)
#There are 2 trophy I'm going for zoologist and skin deep do i need to track the animal also?
rough orchid
surreal cloud
I want you to look at the total progress again, look at the what u have completed already and then look at your own question again
