Shakespearean character with "sharp teeth" (3)

I believe the answer is:

asp

(Other definitions for asp that I've seen before include "Cleopatra's supposed nemesis" , "Kind of snake - what a sap" , "the snake in Cleopatra''s bosom" , "Small viper" , "Cleopatra-killing snake" .)

I've seen this clue in the Newsday.
