The solution to Bit-o-Critter round 28

I’ll chalk it up to the change of domain in the middle of the round, but there were no guesses on round 28 of BoC.  Here’s the solutions:

28A - Flying Squid - Ommastrephes bartramii.  It is a lifelong dream of mine to see one of these bad boys.  Have any of you seen one?  if so where, and what was it like?

28B - Boxing crab, Lybia tesselata.  David Gross, the Round 27 winner picked this one.  I admit I was a bit mean in the crop because I put a bit of the crab and a bit of the anemone it carries.  I know next to nothing about this critter, perhaps David can enlighten us in the comments.  Funky looking thing though, like some sort of submarine cheerleader.
