The Frozen Planet series on the Discovery channel has posted the above trailer on its web site, showing how frozen salty sea water, or brine, will freeze ocean water on contact forming an underwater “brinicle” or brine icicle. The brinicle will freeze any sea creature in its path instantly, which is why it’s called the icy finger of death.
Icy Finger of Death
It’s amazing that ice can form deep underwater like that.
The second video, which is also from Frozen Planet, shows killer whales coordinating a group attack while hunting seals up in the Arctic. The whales swim in unison causing waves that knock a seal off of the ice floe it is desperately clinging to for life.
The video clearly proves that killer whales are highly intelligent.
