By now we are all used to the BBC spending months, if not years, capturing incredibly rare moments in nature. This clip is no exception.
This is the first time a “brinicle” has ever been captured on film. In Antarctica, the crew used stop motion cameras to film an ice formation that snakes its way down from the surface when temparatures fall below zero. When it touches the ocean bed it instatly freezes anything it contacts. Starfish, anemonies, urchins and barnicles suffer an instataneous icy death.
