This fascinating video captures a glimpse of the weird and wonderful animals that live in the aphotic zone. The aphotic zone (aphotic from Greek prefix ἀ- + φῶς "without light") is the portion of a lake or ocean where there is little or no sunlight. It is formally defined as the depths beyond which less than 1% of sunlight penetrates. Consequently, bioluminescence is essentially the only light found in this zone. Most food comes from dead organisms sinking to the bottom of the lake or ocean from overlying waters.

This hilarious video shows the space alien trying eat breakfast with Bob, who is more interested in grabbing an eagle egg from a tree-top nest. Unfortunately, the birds are not cooperating.
This video is a visualization of the northern European airspace returning to full air traffic use after being closed due to volcanic ash. Due to varying ash density across Europe, the first flights can be seen in some areas on the 18th and by the 20th everywhere is open. There are a few gaps (erm, France) and no coverage over the Atlantic, but the picture is still clear.
