Xenia stinks!

Have you noticed how (healthy) Xenia coral stinks when taken out of water?
Yesterday I was working on a frag for Mort and when doing the final
separation from the mother colony I put my nose too close and I was
reminded how stinky this coral was... I already noticed this odor weeks
ago, but I forgot to ask you guys - does your Xenia stinks too?
Have you tried to take it out of water and check how does it smell?
I would like to emphasize, it is not a decaying odor, coral is healthy,
fully expanded, right color and pulsing, but taken out of water stinks!
I would probably expect this stinky odor is a defence agains predators
or something similar like this...
