IntroductionScyllarid and palinurid lobsters are classified into three families (Palinuridae, Scyllaridae and Synaxidae) and share a long planktonic life period as phyllosoma larvae. Of these lobsters, the adult of Scyllarus and Panulirus species can be common and abundant in the coastal waters of Japan as well as in other temperate and tropical waters, including New Zealand and Australian waters. Most of the largesized Panulirus species are commercially important and are targets for fisheries, whereas small-sized Scyllarus species, despite having the largest species number among the scyllarid and palinurid lobsters, are of a low commercial value. In contrast to the Panulirus species, Scyllarus species are usually dominant among the phyllosoma larvae collected in coastal waters .There are many studies about larval recruitment processes of palinurid species, including larval distribution and larval transport/dispersal of Panulirus (Booth & Phillips 1994, Sekiguchi & Inoue 2002. However, few studies about scyllarid species exist (e.g. Inoue et al. 2000, Booth et al. 2005. According to the larval recruitment studies of Panulirus, phyllosoma larvae flush out from coastal waters into oceanic waters, and once again return to the coastal waters where they metamorphose into the puerulus stage to settle (Booth & Phillips 1994, Sekiguchi & Inoue 2002.

Further, larval recruitment studies of Scyllarus contribute to additional resolution of unresolved recruitment processes in Panulirus. Accordingly, exact identification to the species level of field-caught phyllosoma larvae, particularly in the early stages, is essential for understanding larval recruitment processes of Scyllarus lobsters, as well as Panulirus ones.A total of 11 adult Scyllarus species have been reported to date in Japan and its neighbouring waters (Sekiguchi & Inoue 2002) : S. aurora, S. bicuspidatus, S. batei, S. bertholdii, S. brevicornis, S. cultrifer, S. formosanus, S. kitanoviriosus, S. longidactilus, S. martensii, and S. rugosus.Scyllarus species, particularly three species (S. bicuspidatus, S. cultrifer and S. kitanoviriosus) are known to be abundant and dominant among the phyllosoma larvae collected in the same waters (Wada et al. 1985, Sekiguchi 1986a Abstract: For understanding larval recruitment processes of Scyllarus and Panulirus lobsters, exact species identification of field-caught phyllosoma larvae, particularly those of the early stages, is essential. Using ichthyoplankton samples from waters along the west coast of Kyushu to the Japan Sea coast of Honshu and the Kuroshio and KuroshioCounter Current regions, we described morphological features of the I to VIII (final) stage phyllosoma larvae of S. bicuspidatus and the IV to VIII stage larvae of S. cultrifer. The larvae of equivalent stages of two Scyllarus species are...

For spiny lobsters (Palinuridae), the co‐occurrence of final‐stage larvae (phyllosomata) and postlarvae (pueruli) in sampling stations over oceanic waters is indicative of metamorphosis zones, some of which have been found in boundary currents. We hypothesized that metamorphosis of Panulirus argus and P. guttatus off the Mexican Caribbean coast, which has a very narrow shelf, occurs in the swift Yucatan Current (YC). During two cruises conducted in autumn 2012 and spring 2013, a mid‐water trawl and a neuston net were simultaneously towed in night samplings along transects up to ~ 100 km across the YC. Hydrographic and current fields were derived from Conductivity, Temperature and Depth, and altimetry data. Metamorphosis occurred mainly within the YC core. However, velocity and distance to the coast of the YC varied with cruise, and features that may favor retention (a persistent coastal eddy and a countercurrent) were detected. Despite differences in size and condition of pueruli between cruises, their energy stores did not appear to decline during the shoreward migration, suggesting that metamorphosing within strong boundary currents may increase the chances of pueruli arriving more quickly to a shore. Based on previously reported current features and swimming speeds, pueruli metamorphosing up to 12 km offshore are more likely to reach the Mexican Caribbean coast without much loss of energetic reserves. This could also occur for some pueruli metamorphosing up to 30 km offshore if encountering the features favoring retention. In contrast, pueruli metamorphosing > 30 km offshore are more likely to be carried into the Gulf of Mexico and elsewhere.

Scyllarid lobsters, together with the palinurids, have a long-lived, planktonic phyllosoma larval phase in their early life history followed by a much briefer postlarval phase which at settlement completes the planktonic period of their life cycle. Information on scyllarid larval biology and recruitment mechanisms is fragmentary. Scyllarid species exhibit a wide range of larval recruitment strategies and durations, from entire larval and postlarval phases being completed in just a few weeks within lagoons, through to species that become widely dispersed in ocean basins over many months. In contrast, the phyllosomas of all palinurids so far investigated invariably, over many months, become widely dispersed in the open ocean well beyond the continental shelf. Among scyllarid species a general relationship is apparent between adult size and the extent of larval dispersal. During the planktonic period currents, in combination with larval vertical migratory behaviour, probably play an important role in larval dispersal and return. Although varying greatly in size, the postlarval nisto of most scyllarids appears to be similar in behaviour to the puerulus of palinurids. Nistos are usually (if not always) nonfeeding and appear to alternate between swimming at night and resting on the bottom during the day as they move inshore to regain adult grounds before settling and metamorphosing to the first juvenile lobster instar. Those scyllarids with a somewhat abbreviated larval duration and mainly coastal larval distribution-the "flat" species of Ibacus and Thenus-appear to have succeeded in exploiting local currents and biotic systems to restrict larval dispersal and maintain their place. Based on the characteristics of the larvae and their recruitment mechanisms, there is support for the present division of the Scyllaridae into its four subfamilies, but also backing for revision, particularly of the Ibacinae.
