  In gauge theories in the limit of a large number Nc of colors, baryons are
usually described as heavy solitonic objects with mass of order Nc. We discuss
an alternative large Nc description both directly in the field theory as well
as using holography. In this alternative large Nc limit at least some of the
baryons behave like mesons, that is they stay light even at large Nc and their
interactions vanish in that limit. For Nc=3 these alternative large Nc baryons
are equivalent to the standard baryons. In the holographic description it is
manifest that the Regge slopes of mesons and alternative baryons are
degenerate.
