Asymmetry is Awesome.

Asymmetry - - Wonkiness -- Non-Equation
Whatever you call it, it is definitely Characteristic of every Bruce & Sequel Shark!

Explanation:
This is why you rarely see any 'Bruce Shark filmed dead on. 
When you do you will almost always see those eyes and nostrils are very much different and off level, off beam, the crooked mouth, the unbalanced jowls etc... 
Puppet character skins can twist and bunch up on their shape frames here and there through a movement range. There has to be room to move and slide a little between sections.
Bruce being a torpedo shape was severely prone to this. 
So was our mechanical "GhostShark' that we build for SyFy's film.
This is just one of those things that animatronic builders fight. But Bruce's sculpt was not 100% perfectly symmetrical to begin with either.

Our newer sharks are far more symmetrical for sake of proper static shelf display, but not so much as to ditch history. Just naturally though, as much as anyone's face or body is on/off-symmetry. For example, looking in the mirror most people have differences in their nostrils and eyes as far as shape, size and placement. 
Finely measured historical accuracy. It's why our sharks' look 'just right' from every angle and not just `good from one or two angles...
​
Our newer models that are releasing very soon reflect this degree of improved symmetry without throwing reality and screen-used historical accuracy out the window.. Balance is essential.
That and a ten-fold increase in detail and skin texturing...
A better shark getting even better☺!
