  We classify all possible fractional charge vortices of charge less than unity
in spin-1 and spin-2 polar and cyclic Bose-Einstein condensates (BECs) with
zero magnetization. Statics and dynamics of these vortices in
quasi-two-dimensional spinor BECs are studied employing accurate numerical
solution and a Lagrange variational approximation. The results for density and
collective-mode oscillation are illustrated using fractional-charge BEC vortex
of $^{23}$Na and $^{87}$Rb atoms with realistic interaction and trapping
potential parameters.
