“…George & Kensler (1970) extended the list of external characters used by Holthuis & Sivertsen to distinguish species in the 'lalandii' group, and provided support for the subgroups. The morphology of J. caveorurn, a species recently described from the east South Pacific Ocean, suggests its inclusion in the 'frontalis' subgroup (Webber & Booth 1995).…”

“…The following account is primarily based on these 2 species, but also draws on scattered reports of the reproductive biology of the other Jasus spp. The Jasus 'lalandii' group breed in the austral winter (Grua 1963, Holthuis & Sivertsen 1967, Silas 1967, Heydorn 1969, Street 1969, Winstanley 1977, Roscoe 1979, Arana et al 1985, Pollock 1986, Holthuis 1991, Webber & Booth 1995. Fecundity is high (tens of thousands to hundreds of thousands of eggs; Annala 1991).…”

We sampled the distribution of mid-and late-stage (= advanced) Jasus group 'lalandii' rock lobster phyllosomas at 28 approximately equidistant stations across -16 000 km of ocean between the west coast of Africa and the west coast of New Zealand to determine whether the larvae were mostly associated with the patchy allopatric distribution of the adults or were widespread. The Jasus phyllosomas (n = 210) occurred in greatest abundance in the general vicinity of adults. Nucleotidesequencing and restriction-fragment length polymorphism (RFLP) techniques were used to identify 93 of these larvae from 18 stations to species level. Most of the larvae caught were J. lalandii and J. edwardsii, and a few were probably J. paulensis. Most of these larvae were taken near (within a few hundred kilometres) their respective adult habitat off southern Africa, Australia and New Zealand, and Amsterdam Island. The exceptions were small numbers of J. lalandii larvae in the southwest Indian Ocean as far east as Amsterdam Island, adjacent to the J. paulensis habitat, and J. edwardsii larvae across the south Tasman Sea. A single larva off southwest Africa could not be identified to any known Jasus species and may indicate the presence in the genus of an as yet undiscovered species or subspecies. No J. caveorum, J. frontalis, or J. verreauxi (and probably no J. tristani) were found. Our results suggest that Jasus spp. larvae which subsequently recruit to benthic populations use behavioural strategies and/or physical mechanisms to avoid being carried too far away from their parental ground. However, a proportion of larvae, small yet possibly not insignificant, occurs great distances from where adults of the species are known. These larvae are unlikely to recruit to benthic populations, but their occurrence invites further consideration of how Jasus spp. maintain allopatric populations.

“…Indeed, much of the world's oceans remain unexplored and there have been surprising recent findings, a new palinurid genus, Palibythus, and a new Jasus species. 2 Spiny lobsters have many small eggs, a short period of parental care, and a long larval life. 3-5) Early development comprises a larval (phyllosoma, but also naupliosoma in at least Jasus spp.)…”

SUMMARY. The early life history of shallow-water palinurids consists of a long-lived (months), widely dispersed coastal then oceanic phyllosoma larval phase, followed by a much briefer postlarval puerulus phase that is first oceanic and then benthic. Our knowledge of larvae, and postlarvae before settlement, is still fragmentary. Many species remain undescribed; in few is larval ecology known beyond that based simply on sparse distributional data; even feeding is poorly understood. But it is increasingly clear that the oceanography and larval behaviour are important in larval retention and recruitment. The way forward with the likely paucity of dedicated phyllosoma sampling in the near future is through larval culture, opportunistic plankton sampling, fuller use of historic plankton collections, modelling of larval trajectories, and use of developing technologies such as bioacoustics. Pueruli are essentially non feeding, and the oceanography and ocean climate affect settlement levels. Settlement takes place in structurally complex items such as algae, or in holes and crevices in rock.
