Hydruka

Hydruka are Rahi who are known to be ill-tempered.

Hydruka were herd Rahi of the inhabitants of Mahri Nui. They were used by the Matoran to harvest Airweed, which was used by the Matoran to create air bubbles for them to live safely underwater. They also had the ability to create Solidified Air Bubbles that could be launched at sea creatures. Hydruka were the favorite prey for Ehlek's eels. Like Nocturn, they were unaffected by the mutagenic water surrounding Mahri Nui. Two notable Hydruka are Morak and Thulox. They still remain in the sea after Mahri Nui was destroyed and the Matoran left.
