Coenobita violascens

The shield of the first stage crab (1.06–1.07 mm SL) has faint reddish pigments (Fig. 13 A, B); they develop as two longitudinal dark reddish brown bands on the middle portion and a dark reddish brown band at the anterior lower portion of each side wall of the whitish/creamy shield in juveniles with an SL of> 1.1 mm after one month of age (Fig. 13 C–F, 14A–F). The ocular peduncle of the first stage crab is reddish (Fig. 13 A, B); it gradually becomes a whitish color dorsally and laterally and develops a dark reddish brown band ventrally (Fig. 13 C–F, 14A–F). The ocular acicles and the upper edge of the shield exhibit a reddish brown color in juveniles with an SL of> 1.4 mm after three months of age (Fig. 13 E, F, 14A–F). The chelipeds and the second and third pereiopods of first stage crabs are brownish red, excluding the distal and proximal parts of each segment; they appear to have whitish rings at the boundaries between segments (Fig. 13 A, B). The whitish part becomes prominent in the left second and third pereiopods, especially at the distal propodus of the left third pereiopod (Fig. 13 E, F, 14A–F). Longitudinal white stripes develop on the middle and ventral portions of the left cheliped palm (Fig. 13 E, F, 14A–F).
