The famous Northwest Passage has become infamous in recent years, as Arctic sea ice coverage shrinks and leaves an open waterway between the Atlantic and the Pacific Oceans. We tend to think of this in terms of what it means for human transport and drilling, but we're hardly the only fish in the sea. Are there any other species taking advantage of the chance to explore?

A Reuters article by Michael Ricciardi says Yes:

From microscopic plants and jellyfish to predatory packs of Orcas and soon-to-be-arriving squid...The "alien" invasion of the Atlantic ocean by Pacific Ocean species is fully underway, all made possible by ever-decreasing Arctic sea ice cover.

I don't doubt there are marine organisms making the crossing. But wait a minute, which squid is he talking about? 

Humboldt squid - normally found off the coast of Chile - recently have been found in colder Alaskan waters, and they are predicted to make it across the Arctic into the Atlantic perhaps within another year.

Oh come on! Who predicted that? I've been prodding my network of fellows Humboldt squid researchers, and no one will 'fess up. I think it's far-fetched, to say the least. Humboldts have been seen in Alaska, sure, but in the panhandle, not the Aleutians. And they're not exactly abundant there.

This is my skeptical face. ;-/
