  We show that the amoeba of a generic complex algebraic variety of codimension
$1<r<n$ do not have a finite basis. In other words, it is not the intersection
of finitely many hypersurface amoebas. Moreover we give a geometric
characterization of the topological boundary of hypersurface amoebas refining
an earlier result of F. Schroeter and T. de Wolff \cite{SW-13}.
