The reason I think Paramites are invertebrates is becuase a) Max's quote from AO, and also if you look at them the way their bodes are shaped looks likethey can't really have a spinal column, and I'd imagine they have either an exoskeleton that is very hard to notice (and thus blends with the skin) or they have cartilage/gristle where you'd expect the spinal column to be, rather than bone.
