It's more like a kick-ass smoke screen. Lots of cephalopods(octopi, squid, cuttlefish, nautilus, allonautilus) have it. It's used to hide them while they escape danger.

I assume that the Kraken and Scylla use it similarly, though maybe also to cover themselves as they attack.

EDIT: I mean to say I assume those are the primary uses outside of those mentioned in the profiles.
