Deep Sea Threshfins are a species of Threshadon native to the oceanic waters of Azeroth. While they have only been noted to come close enough to the surface to be observed around Darkshore, and even then only in the very northern portions, it can be presumed that they inhabit large tracts of the sea far off the coast in deep water, perhaps even to depths including the twilight zone or deeper. They generally will not attack sapients unless provoked, which is odd given the personality traits of all other Threshadon species. While this may be worth study, no one has yet done so.
