Kiyi (Coregonus kiyi)

Don't be fooled by those big, animated eyes; kiyi are feisty. Moving about in the shadowy regions of Superior's deep waters, they hunt their freshwater quarry (Mysis) with efficiency and speed. They rise as the Mysids rise by night and sink with them by day, all the while using those big eyes to watch for incoming lake trout. These coregonids run by the aliases: bigeye cisco, deepwater cisco and deepwater chub. The other Great Lakes lost all of their kiyi but in Lake Superior they're thriving, outnumbering the combined populations of ciscoes and bloaters.
