Loom

This is how the nature works, it is terrifying but it is the reality.  This video is so scary there are really no words for it!  The moth is captured in a spider web and then the spider comes to eat it!  The video shows every detail of how it happens!

All of this is shown in great detail - and close up.  It is easy to forget that this is in fact an animation and that these creatures are not real at all.
