Aruganosu are classified as a member of the Piscine Wyvern class. Its closest known relatives are the beautiful golden Goruganosu and the volcanic-dwelling Lavasioth. It is treated as another species or close relative of Lavasioth by the Guild.
It is unknown whether Aruganosu and Goruganosu are the same species or two different species of Piscine Wyvern.
So far they have only been seen inhabiting the Tower.
Due to Aruganosu being recently discovered, it is unknown how it fits into the ecological niche.
Aruganosu, along with Goruganosu, are currently the only Piscine Wyverns capable of burrowing through solid ground. Unlike other Piscine Wyverns, Aruganosu is able to use the Ice Element to attack foes, even producing icy tornadoes. Encased in some of this ice is a paralyzing fluid that could potentially paralysis prey. The scales of the Aruganosu are said to be cold as ice and are reflective to light.
Aruganosu are territorial creatures and is said to be locked in combat with Goruganosu.
