Figure 1

Ultrastructure of the eastern spiny lobster cuticle across metamorphosis. Left panels show an intermolt stage of last phyllosoma (instar 17; top), early post molt puerulus (mid) and intermolt juvenile of the eastern spiny lobster Sagmariasus verreauxi. The cuticle of the corresponding stages was observed and photographed under scanning electron microscopy with increasing magnifications from left to right. Dashed rectangles signify the region zoomed in on the photo to the right.
