Primeval Hunters appear like oversized red wolves with enormous fangs, and do not have any special abilities. They may spawn in packs from 1-3 to 10+, not mentioning support of other monsters. They run very quickly, and may efficiently block path.
Visually, they look exactly like Companion wolves, except for color.
Aletur has a pack of dozen or so war wolves of unique blood and white color.
Primeval Hunter was designed to be a more natural enemy than some of the other island's more supernatural monsters.
