Now that I've completely thrown the topic off-balance with the name suggestions...
Are there any other comments on Boz's stats?
There seems to be plenty of support for and against a spit attack.
I think we should probably lay aside any arguments which rely upon real-world physics, since this is a fantasy creature, and by giving it spell-like abilities at all, we depart from the normal realm of archer fish and the like. Environment and ecology should be factors, but we should be able to use some imagination, considering the context.
Likewise, we aren't required to give it actual magical abilities, for the examples given above include many which lack them.
That said:
I think some mechanism for holding on to rocks is needed, and I think spider climb would be the best way to render that ability.
Camouflage could best be rendered as a conditional bonus, such as +10 to Hide checks made in aquatic environments.
Spit attacks - we shouldn't feel obligated to give this creature a way to attack airborne creatures. It would derive much of its sustenance as a sea anemone would, only on a larger scale. Any airborne creature which gets close enough would be killed by its tentacles, however, which would discourage such attacks by seagulls or other airborne oceanic predators.
If enough people want a spit attack, however, there is always the possibility that it has learned to spit the enzymes it uses to digest food -- the Ankheg certainly does.
