An internal symmetry is a transformation acting only on the fields, therefore not transforming spacetime points, and leaving the lagrangian or the physical results invariant. Example of internal symmetries are gauge symmetries. These are local symmetries, which means the transformations are in general spacetime dependent ...What is the symmetry of this organism?

$\begingroup$ @ d_b, thanks for the comment. My confusion arises exactly from your point. I thought when we say we have a gauge theory we have a theory with a local symmetry and the gauge fields are the connections of the Lie group but then I came across the following paper.There, we have a color vector charge $\vec{q}$ with a global SO(3) symmetry in color space and gauge symmetry for the ...Clams and their relatives (oysters, scallops, and mussels) are often called bivalves (or bivalved mollusks) because their shell is composed of two parts called valves.
