Such as we get eaten by predators here on Earth.
Zaria also has some predators of her own who find them as a wonderful meal for them, they become so unseen that they blend in the background of the alien vegetation and without looking they snatch them with there hook-looking-mouth and pulling them in there mouth.
ZepTron helps Zaria because once she gets inside the worse part will happen! :S
