Fig. 9From: Sea urchin growth dynamics at microstructural length scale revealed by Mn-labeling and cathodoluminescence imagingModel of interambulacral ambital plate development (modified after [58]). a tangential view, b meridional view. Arrows indicate directions of the growth fronts. Mean growth rates per each species in a given direction are highlighted in color (black = Paracentrotus lividus, red = Echinometra sp., green = Prionocidaris baculosa)Back to article page
