“…In the Ryukyu Archipelago, it has been reported that larval release occurs from late June to late November in C. rugosus , from mid‐June to early September in C. cavipes and C. purpureus on Okinawajima Island (26°08ʹN, 127°47ʹE) (Nakasone ), and from late July to early October in C. violascens on Iriomotejima Island (24°24ʹN, 123°46ʹE) (Doi et al. ). Ovigerous females of B. latro with eyed eggs (containing unhatched zoea larvae with pigmented eyes) were found from late June to late August on Hatomajima Island (24°28ʹN, 123°49ʹE) (Sato & Yoseda ).…”

Terrestrial hermit crabs in the family Coenobitidae (genera Coenobita and Birgus) are distributed in tropical and subtropical regions. They occupy various habitats ranging from shore to inland forests, and the two shore‐dwelling species, Coenobita rugosus and C. violascens, possess different distributional characteristics on Ishigakijima Island, Ryukyu Archipelago, Japan. Coenobita rugosus is distributed throughout the coast of the island and is abundant in beach areas, whereas C. violascens has mainly been found in river mouth areas. However, very little is known about the habitats used by the early life stages of coenobitid crabs because identifying the species of recently landed early juveniles is difficult. We tested whether the species compositions of early juveniles of coenobitids differed between beach and river mouth sites on Ishigakijima Island. We collected and identified the early stage coenobitids using PCR–RFLP techniques. A total of 576 early juveniles of five Coenobita species were collected, of which 0.7% were C. brevimanus, 7.3% were C. cavipes, 0.2% were C. purpureus, 70.1% were C. rugosus, and 21.7% were C. violascens. The early juveniles of Birgus latro were not found. The early juveniles of C. rugosus occurred at both beach and river mouth sites, and they were abundant at beach sites. The early juveniles of C. violascens were only found at river mouth sites. These findings indicate that C. rugosus and C. violascens complete their life cycles on land near the localities where they land. The early juveniles of the inland‐dwelling species, C. cavipes, were also mainly collected from river mouth sites, which suggested that juveniles of C. cavipes selected landing sites near river mouth areas and then migrated into the inland forests, passing through riverside areas. Our results highlighted the importance of river mouth areas for recruitment to adult habitats by some coenobitid species.

“…The habitat type of this study area may have resulted in relatively small numbers of specimens of C. violascens in the samples because this coenobitid is mostly recorded from habitats related to mangrove and terrestrial areas near estuaries (Nakasone 1988;McLaughlin et al 2007;Doi et al 2016). The present study site is supralittoral sandy beach that is not the most preferred habitat of this species.…”

“…McLaughlin (2002) reported the occurrence of C. violascens from coasts of the Andaman Sea and Gulf of Thailand. Coenobita violascens mainly inhabits beaches and areas associated with mangroves (Nakasone, 1988;McLaughlin et al, 2007;Doi et al, 2016). Limited information on the life history of C. violascens has been known and recorded.…”

“…Limited information on the life history of C. violascens has been known and recorded. Only some recent studies on C. violascens have been recently reported, including functional morphology related to water uptake (Becchi et al, 2015), emigration behavior and molting during the sea-to-land transition (Hamasaki et al, 2015a), larval development under laboratory conditions (Hamasaki et al, 2015b;Kato et al, 2015), larval release and tree-climbing behavior (Doi et al, 2016) and thermal adaptation of embryos (Hamasaki et al, 2016). The objectives of the present study are to reveal shell occupation and the relationship between the characteristics of occupied shells and crab characteristics of C. violascens at Cape Panwa, Phuket Island, Andaman coast of Thailand.…”

“…They are found on shores, inland areas, coastal forests, rainforests and arid scrublands of small islands or narrow coastal strips (Hartnoll, 1988;Greenaway, 2003). Because their aquatic larvae need saline water to hatch (Hamasaki et al, 2018a), ovigerous females of coenobitids move to the water s edge and release larvae into seawater (Yamaguchi, 1938;de Wilde, 1973;Imafuku, 2001;Nakasone, 2001;Nieves-Rivera & Williams, 2003;Doi et al, 2016Doi et al, , 2018a. Larval release by coenobitid crabs takes place in the swash zone, which allows us to directly observe those behaviors, unlike aquatic species, which release larvae underwater.…”

The seaward migration and larval release of Coenobita brevimanus Dana, 1852 on a sandy beach of Iriomote Island, Japan, was studied between May and November 2009 and between May and December 2010. Seaward migration and larval release were mainly observed for several days before and after new moons during the period from June to November, and the migration was mainly focused on 0.82 days after the new moon. Around full moons, some crabs were also found, with the highest numbers at 1.34 days after spring tides (semi-lunar rhythms). Almost half of the crabs that appeared on the beach entered seawater, and almost half of the immersed crabs released zoeas or exhibited swinging behavior. Appearance of crabs on the beach and entering seawater occurred only after sunset between 19:00 to 23:10. The peak time of the appearance on the beach was within a certain range each month. Crabs entered seawater at a mean of 2 h after the nighttime high tide. Seaward migration of the crabs showed clear seasonality, and many crabs migrated and entered seawater during the period from July to September, the months with higher temperature (25°C). This species shows a phenology and rhythm of spawning common to coenobitids on the Ryukyu Islands.
