  The holographic configurations dual to Wilson loops in higher rank
representations in the ABJM theory are described by branes with electric flux
along their world volumes. In particular, D2 and D6 branes with electric flux
play a central role as potential dual to totally symmetric and totally
antisymmetric representations, respectively. We compute the spectra of
excitations of these brane configurations in both, the bosonic and fermionic
sectors. We highlight a number of aspects that distinguish these configurations
from their D3 and D5 cousins including new peculiar mixing terms in the
fluctuations. We neatly organize the spectrum of fluctuations into the
corresponding supermultiplets.
