A video from the British Museum of Natural History posted on 3 Quarks Daily discusses an unusual defense mechanism in snakes: cobra spitting. 

The film (10m 30s) is about research into many aspects of this unusual behavior--not all cobras spit venom--with an emphasis on its evolution in cobras where it occurred quite independently in different geographic areas. It includes some remarkable video of venom spitting and how yhis phenonmenon is studied.

Now if it gives you the "willies," you are probably not alone! I hope you take a look.
