I'm curious of what would happen in a Kaarme tried to take genetic information from a Shuunai. Assuming their DNA could actually be used (plant DNA and creature DNA don't often meet eye to eye) I feel confident a Shuunai could survive the event with their regeneration and the fact that their body-fluids aren't as vital to their survival as most life forms are. I'm pondering this. 

Overall I think they're a really cool species, even if they spend their time going around the galaxy and sexually molesting things.
