I'd appreciate the queen facehugger more if we'd been given a better reason for its appearance.
For example, maybe it started out looking like a normal facehugger (like we saw in the opening sequence), but then it rapidly adapted to the harsh aquatic environment of Fiorina's ocean after the EEV's splashdown.
The webbing, armor plating and spikes would be the end-result of the "funny little habit" that Ash described in the original movie so it could swim and protect itself against the planet's carnivorous little sea-bugs.
