The lovely oceans are mostly populated by harmless primitive herbivores, the "Shiarya", that feed in the mountains by hunting a substance called "Byaha Ge" in the shade. Shiarya are somewhat related to Zuryo Chuju Mo and have 6 legs and vary in length from 50 to 120 mm. The Shiarya can survive temperatures from 40 to 80°C but are killed by drought.
