Figure 2 in Morphological and histological study of the scales of the grey notothen, Lepidonotothen squamifrons (Günther 1880) (Nototheniidae; Perciformes; Teleostei)

Figure 2. – Superficial view of scales (SEM). A: Detail of the circuli of the anterior area near the anterior margin. We show three radii (arrowheads) and the circuli with some very thin spines at their tip. In the inset, detail of the spines at the tip of the circuli. (scale bar = 7 μm). B: Detail of the circuli of the anterior area near the focus, between two radii. The circuli are thicker than the more anterior ones (compare with Fig. A). C: Detail of the posterior area. Four cteni are seen, the base of which are fit each other and with more ancient ctenial bases. Scale bars: A, C = 100 μm; B = 25 μm.
