Google for "polossatik". What do you see? A bunch of articles (including one from wikipedia, and [in the extended results] way too many from Wikipedia clones) about Orcas, or Killer Whales. All of them maintain that "polossatik" is an Aleut name for Orca, and that it means "the feared one".

In reality, "polossatik" (or, more commonly, "polosatik") is indeed a name for a whale, just not for the Orca. It's a Russian word meaning "a striped one", and as  such it is applicable to any number of so-called rorqual whales, or Balaenopteridae. The word "rorqual" itself means "grooved" or "furrowed" or somesuch in Norwegian. They belong to different suborders in order Cetacea. Orcas are toothed whales (Odontoceti) and rorquals are baleen whales (Mysticeti).
