For the first time ever, BBC nature photographers have captured footage of an underwater brine icicle (also known as a "brinicle") slowly expanding underneath the ice of Antarctica's Little Razorback Island. Woe to be a starfish or urchin that encounters this briny deathtrap!
Frozen Planet's cameramen Hugh Miller and Doug Anderson have captured the formation of a brinicle for the first time ever. I didn't know what a brinicle was until I saw this video. I just can't believe this can happen.
