Comparison of Dendraster species
Description The three extant species of Dendraster in comparison: Dendraster excentricus: The apical system is strongly eccentric; the aboral spines are distinctly club-shaped and the food grooves reach a little onto the aboral side. Dendraster terminalis: The apical system is small and the least eccentric, the aboral spines are slightly thickened and the food grooves do not extend onto the aboral side. Dendraster vizcainoensis: The apical system is slightly eccentric, the aboral spines are thickened with pointed tips and the food grooves reach onto the aboral side as far as into the petals.
