    What are the icy fingers of death?
    The structures have been called "icy fingers of death" because of their ability to freeze living organisms. Nature’s grace and fury find equal measure in unique formations called brinicles or more evocatively “icy fingers of death.” The strange phenomenon that forms these underwater icicles can be found in the oceans of the planet’s polar regions.

    What are the icy brinicles of death?
    I thought to myself, "Now this is a unique example of freezing point depression!" This phenomenon is informally known as the Icy Brinicles of Death because the supercooled brine solution formed also freezes any sea life that comes in contact with it as can be seen in the embedded BBC video below (run time = ~2 mins).

    What is a brinicle in geology?
    A brinicle ( brine icicle, also known as ice stalactite) is a downward-growing hollow tube of ice enclosing a plume of descending brine that is formed beneath developing sea ice . As seawater freezes in the polar oceans, salt brine concentrates are expelled from the sea ice, creating a downward flow of dense,...

    What happens when the brinicle becomes self-sustaining?
    When the brinicle becomes thick enough, it becomes self-sustaining. As ice accumulates around the down-flowing cold jet, it forms an insulating layer that prevents the cold, saline water from diffusing and warming. As a result, the ice jacket surrounding the jet grows downward with the flow.
