“…Ibacus juveniles appear to migrate shoreward from offshore waters to recruit into adult grounds [61]. Juveniles appear to occupy a different spatial niche from adults and are far more cryptic than adults because few individuals are found that are smaller than 20 cm TL [65,66]. To obtain sufficient numbers of small individuals, specific sampling techniques must be developed which target the juveniles, which may prove difficult if many of the species have juvenile development in deep, oceanic waters.…”

“…Scyllarides spp.) are typically large and tag-release studies suggest that adults molt annually (S. latus, [70]), although data from S. astori populations suggest that molts occur every 18-24 months [65,66]. Molting typically occurs at night and in cooler to warmer months [71][72][73].…”

“…Sex ratios are close to unity in those species that have been adequately sampled (S. latus, [26,72]; S. astori, [65]). In some species, mean CL is larger for females than for males (S. latus, [26,74]), while in others, males exceed females in size (S. astori, [66]). Shortly after mating, females extrude a large number of eggs (conservative numbers range from 24,710 to 356,000), based on TL of the individual, with those eggs ranging from 0.6 to 0.7 mm diameter [26,66,[75][76][77].…”

“…Eggs are brooded for 2-8 weeks before release over a number of days (S. latus, [74,78]). Ovigerous females are more commonly sampled in cooler months, but not warmer months [66]. There is some evidence that females may return to inshore reefs in the autumn earlier than males and leave sooner after shedding eggs in the mid-summer, possibly to maximize thermal regimes for developing embryos [79].…”

The family Scyllaridae is the most speciose and diverse of all families of marine lobsters. Slipper lobsters are found in both tropical and temperate habitats with hard or soft substrates and at different depths, and exhibit a wide array of morphological, anatomical, and physiological adaptations. Among the 20 genera and at least 89 species constituting 4 subfamilies, only some members of 4 genera, Thenus (Theninae), Scyllarides (Arctidinae), Ibacus and Parribacus (Ibacinae), form significant fisheries because of their large size. While scientific information on these lobsters has increased considerably in recent decades, it is still limited compared with commercially valuable spiny and clawed lobsters, and is confined to a few key species. The present chapter presents the current available knowledge on the biology of scyllarids and attempts to point out where questions remain to help focus further studies in this important group. Scyllarid Lobster Biology and Ecology DOI: http://dx.doi.org/10.5772/intechopen.88218 to deep water (offshore) species [5]. These same molecular tools suggest that two Atlantic species, Scyllarus depressus and S. subarctus, are a strongly supported clade with low genetic differentiation, indicative of a recent split into sister taxa [22]. Crustacea Life historyThe life history of scyllarids parallels that of palinurids and can be divided into a series of developmental phases. These lobsters typically begin their pelagic lives

“…Several populations of slipper lobsters have, therefore, been depleted and some even became rare in part of their distribution range due to overexploitation (Radhakrishnan et al, 2005(Radhakrishnan et al, , 2007. In response to over-fishing of palinurids, fishermen in various locations tend to quickly shift their efforts to slipper lobsters, which further endanger those species (Hearn et al, 2007). Urgent measures should be taken in cases of overexploited and declining populations, in an attempt to recover the population or at least stop its decline.…”
