Figures & data

Figure 1. Cross-sections through phalanges of adult Neurergus crocatus. A, Male 71.52 mm SVL. Ten LAGs were observed in the periosteal bone. Metamorphosis line (m.l.) and the first LAG were distinct. This individual was 10 years old. B, Female 72.02 mm SVL. Ten LAGs were observed in the periosteal bone. The first LAG was completely destroyed by endosteal resorption. This individual was 11 years old. Since all specimens were collected in the breeding season, the outer margin of the bone did not regard as a LAG. e.b., endosteal bone; e.r., endosteal resorption; m.c., marrow cavity; m.l., metamorphosis line; p, periphery.
