Not to mention that the monkeys only attack after Kitai angers them by throwing a rock at one. Sure, the river parasite, the giant bird, the panthers, and the monkeys try to kill him, but aside from the Ursa, those are all that go after him here. Furthermore, for a planet where everything has evolved to kill humans, there aren't many creatures that try to outright kill Kitai."Everything on this planet is evolved to kill humans." How does this make any sense at all? Why and how would animals adapt to kill something that hasn't been there for centuries?.Why don't humans just wear sealed suits instead of learning to mask their emotions? Would allow everybody to be a "ghost" winning the war with little effort.Or a civilization which doesn't bother building a full-body fear-masking suit or a robot that would make fighting Ursa easier.

I'm even more surprised that the Ursa can smell subtle scent of pheromones secreted by fear, but can't smell the horrible stench of a boy who has been running, jumping and fighting for days without a shower.I'm more surprised by the fact that a space faring species that can create monsters that see fear, doesn't add another sense of sight once the first one has proved to fail.Why not just have the Ursa sense humans regardless of emotional state? On the other hand, a bunch of blissfully unaware humans who do not know to be afraid are going to pass right by an Ursa's attention when they would in fact be more vulnerable then. When a human is afraid of a nearby Ursa, they are probably going to try to either flee or fight. How does the Ursa sensing their prey by fear make any sense? When you look at predators in the wild, they often try to catch their prey unaware.
