 Antrechinus mortenseni (apical system) Description Apical system of female (left) and male (right): In the female the terminal plates (T I - I V) are enlarged. The genital plates (G 1 - G 4) are much reduced, because there are no gonopores. The gonoducts coming from the gonads lead directly into the internal brood pouches. In the centre of the plate system the apical aperture opens, where the juveniles emerge after having finished their development. In the male the apical system is elongated as usual in holasteroids. The ambulacral plates carry only a single pore.Scale 1 mm.JPG file - 88.26 kB - 1 340 x 765 pixelsadded on 2005-02-23295 viewsFrom reference Schultz, H. (2006).
