Lake Threshers are a subspecies of Threshadon which are found within Lake Everstill, a large lake in the middle of the Redridge Mountains of the planet Azeroth. Like nearly all other species of Threshadon, they are hostile. They presumably predate mainly on the high Murloc population in the area, which would help keep their numbers down to keep them from overbreeding (although in recent years adventurers have also helped lower the population of these Murlocs as well, although they do not seem to be in immediate danger of extinction).
