A "Brinicle" ... what the heck is that?

Yup - that's exactly what we said when we saw this article from Nature news ... 'Brinicle' ice finger of death....

In the Antarctic, as new sea ice forms on the ocean surface it leaves behind brine that is so salty and dense, it rapidly sinks towards the sea floor. As this salty slurry sinks, it instantly freezes the water surrounding it - forming a salt icicle, or a brinicle - which freezes everything in its spidery path, including starfish and sea urchins.

For the first time ever, this "icicle of death" was captured in time-lapse photography by cameramen Hugh Miller and Doug Anderson for an upcoming series called Frozen Planet, from BBC One.
