Tongue

Thalassara can use her tongue to paralyze her prey even if they are larger than her. This is a useful attack to allow a single Draknarith to either get away, feast on another creature or gain information. 
This is a natural defense of the Draknarith species young. They possess a very long tongue that they can quickly launch out of their mouths for several feet. It has a poison gland at the bulbous end so that when the tongue hits its target it releases enough poison to render it unable to move, or unconscious if hit twice (it doesn't kill).
