Coenobita rugosus
No full textCoenobita rugosus The first stage crab (0.92–0.97 mm SL) has a whitish shield and brownish pigmented ocular acicles (Fig. 11 A– C). The pigmentation of the ocular acicles changes to dark brown in juveniles with an SL of> 1 mm after one month of age (Fig. 11 D–F, 12A, B, D, E). The upper edge of the shield is brown/dark brown in juveniles with an SL of> 1.3 mm after three months of age (Fig. 11 E, F, 12A, B, D, E). After four months of age (> 1.8 mm SL), the shield has a brownish stripe on the anterior lower margin of each side wall in some juveniles (Fig. 12 B, G–I) and the ocular peduncle of all specimens has a ventral brownish band (Fig. 12 B, C, F–I). The chelipeds and the second and third pereiopods of the first stage crab are reddish (Fig. 11 A, B); they vary in color pattern after four months of age, with brown bands on some segments (Fig. 12 A, D–I). The palm of the left cheliped has a brown stripe/patch with a large variation in area on the posterior middle portion (Fig. 12 F–I).Published as part of Hamasaki, Katsuyuki, Tsuru, Takuma, Sanda, Tetsuya, Fujikawa, Shunsuke, Dan, Shigeki & Kitada, Shuichi, 2017, Ontogenetic change of body color patterns in laboratory-raised juveniles of six terrestrial hermit crab species, pp. 521-545 in Zootaxa 4226 (4) on page 537, DOI: 10.11646/zootaxa.4226.4.5, http://zenodo.org/record/26513
Coenobita cavipes
No full textCoenobita 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).Published as part of Hamasaki, Katsuyuki, Tsuru, Takuma, Sanda, Tetsuya, Fujikawa, Shunsuke, Dan, Shigeki & Kitada, Shuichi, 2017, Ontogenetic change of body color patterns in laboratory-raised juveniles of six terrestrial hermit crab species, pp. 521-545 in Zootaxa 4226 (4) on page 529, DOI: 10.11646/zootaxa.4226.4.5, http://zenodo.org/record/26513
