  In this work we study and compare the features of gravitational entropy near
the throat of transversable wormholes formed by exotic matter and wormholes in
galactic halos. We have verified that gravitational entropy and entropy density
of these wormholes in regions near their throats are indistinguishable for
objects of same throat, despite the fact they are described by different
metrics and by distinct energy-momentum tensors. We have found that the
gravitational entropy density diverges near the throat for both cases, probably
due to a non-trivial topology at this point, however allowing the interesting
interpretation that a maximum flux of information can be carried through the
throat of these wormholes. In addition, we have found that both are endowed
with an entropic behaviour similar to Hawking-Bekenstein's entropy of
non-rotating and null charge black holes.
