From recent study of properties of the lowest spin-parity 1/2- baryons, N^*(1535) and Δ^*(1620), new pictures for the internal structure of the lowest 1/2- baryon octet and decuplet are proposed. While the lowest 1/2- baryon octet may have large diquark-diquark-antiquark component, the lowest 1/2- baryon decuplet is proposed to have large vector-meson-baryon components. Evidence for the "missing" members of the new pictures is pointed out and suggestions are made for detecting these predicted states from forthcoming experiments.
