Birds with the highest metabolisms can slow thier metabolism at night to prevent starvation and sleep. Shrews can't do this and most sleep only ten to 15 minutes at a time. Otherwise they would starve to .

Unlikely. Losing your keys is not a matter of life and and never will be, unless somebody threatens to blow your head off unless you give him the keys

Lost power for a week last winter and it really makes you appreciate modern convieniences. (like running water... ick)

No I mean eyes. The box jelly has 24 eyes, complete with lens, retna and iris. No brain, but they see and react to what they see, however blurry the image. Jellies are full of surprizes.

It takes a surly and smart prey animal to systematically attempt to kill its predators.
The most dangerous weapon is the simplest one.
Complexity isn't always superiority.
