Coenobita cavipes

The shield of the first stage crab (0.97–1.03 mm SL) has faint brownish pigments (Fig. 7 A, B); they develop as two longitudinal brown bands/patches on the middle portion and a dark brown band at the anterior lower portion of each side wall of the whitish/creamy shield in juveniles with an SL of> 1.2 mm after one month of age (Fig. 7 D–F, 8A–D, G). The ocular peduncle of the first stage crab has a brownish pigment area ventrally (Fig. 7 C), and it gradually develops to a dark brown color after one month of age (Fig. 8 E). The ocular acicles and the upper edge of the shield exhibit a brown color in juveniles with an SL of> 1.3 mm after two months of age (Fig. 7 F, 8A). The second and third pereiopods of the first stage crabs are reddish brown, excluding the distal and proximal parts of each segment; they appear to have whitish rings at the boundaries between segments (Fig. 7 A, B). The palm of the left cheliped begins to develop brownish pigment areas on the upper and lower parts after one month of age (Fig. 7 D, E); specifically, the pigment on the lower part develops as a distinct large brown patch, and the palm appears to have a longitudinal white stripe on the middle portion (Fig. 7 F, 8C, D, F, G). The brownish bands also develop on the carpi and meri of the chelipeds, and the bands of the pereiopods become dark brown (Fig. 7 D–F, 8C, D, F, G).
