Dangerous rattlesnake (10)

I believe the answer is:

sidewinder

(Other definitions for sidewinder that I've seen before include "Rattlesnake; misile" , "Rattlesnake with distinctive motion" , "Rattlesnake - air-to-air missile" , "Burrowing snake" , "1 of 21 [SNAKES] ?" .)

I've seen this clue in The Wall Street Journal.
