Ursadon

Ursadons comel sangat are apex predators indigenous to the snowy planet Braxis with no natural enemies. Due to their adaptation to their home environment, they thrive in snowy, frozen wastelands. They hunt their prey within the local icy waters, very likely indicating an ability to swim powerfully. Their species was at one point in recent history transported to a number of other ice worlds, including a dark moon that the Protoss Zeratul encountered on one of his journeys.

Instances involving attacks on Humans are rare, but the few recorded instances of an enraged Ursadon attack have all ended in tragedy. The Koprulu Wilderness Society has recommended that all sapients keep a safe distance from Ursadon populations both for the safety of the observer as well as that of the Ursadons themselves.

Unfortunately, their homeworld of Braxis was purified by the Protoss under the leadership of Artanis due to Zerg infestation, rendering the Ursadon extinct in their natural environment. How they fare on worlds they were transported to is as of yet not documented.
