“…A total of 927 specimens testified the occurrence of 14 planktonic taxa, accidentally trapped by algal covering, here reported as a contribution to the knowledge of the overall mollusc diversity in the Scilla area. All Atlanta species had a circumtropical distribution that includes the Mediterranean Sea, but while A. peronii and A. lesuerii are known in the whole Mediterranean, A. inflata has been reported only in the western basins, differently from A. brunnea and A. helicinoidea which are confined in the eastern basins (Wall-Palmer et al, 2018). This latter taxon is confirmed for the Italian seas, after a first ascertained record from Scilla (Giacobbe & Renda, 2018).…”

The mollusc taxocoenosis characterizing the photophilic zone of the Scilla cliff (Strait of Messina, Central Mediterranean) has been described on hard bottom samples from 6, 16 and 24 m depth. Seasonality has been evaluated by replicates carried out in autumn and spring. Overall, 229 benthic taxa have been recorded, 87 of which occurred in both seasons, while 109 were exclusively recorded in spring and 29 only in autumn. Specimen abundance also notably decreased from autumn to spring (1581 and 892 individuals, respectively). Depth scarcely affected the species distribution, probably due to water transparency, thermal homogeneity, and nutrient mixing. The recorded species cannot be all assigned to the photophilic rocky habitat, since ubiquitous taxa, organisms of other habitats settled in micro-enclaves, and juveniles of not established species have been frequently recorded. The role of algal covering as larval collector from disparate habitats is confirmed, as also proved by the high occurrence of planktonic molluscs (14 species) in all the examined samples. The whole mollusc taxocoene, whose diversity is high with respect to other areas at comparable latitudes, showed a marked western footprint, in accordance with the known biogeographic peculiarities of the Messina Strait.

“…Maximum likelihood analyses of individual genes recovered species and genera with varying levels of success (Figs S1-S3). While all 34 previously known putative atlantid species [11] (including all 24 morphospecies) were resolved by the CO1 phylogenetic tree (supports of >80%, 100% for most), two additional putative species were also detected and veri ed by ABGD analysis (one within A. peronii C, and one within O. in atus A). This brings the total number of putative species to 36, of which 24 are described as morphospecies and 12 are undescribed putative species.…”

“…Relatively recent local extinctions have been reported for several atlantid species. Atlanta plana Richter, 1972and Atlanta turriculata d'Orbigny, 1836are not found in the modern Atlantic Ocean [11], however, fossils of both species have been found in Late Pleistocene sediments of the Caribbean Sea [12], and A. plana has also been found in Pliocene rocks of southern France and southern Spain [13,14]. These records suggest the local extinction of A. turriculata at around 16 thousand years (ka), and A. plana in the last 3.5-1 ka.…”

“…Only a single large-scale study has previously explored the molecular phylogeny of the atlantid heteropods [31]. Wall-Palmer et al [31] revealed considerable hidden diversity using a global dataset of mitochondrial cytochrome c oxidase subunit 1 (CO1) sequences from specimens of all known atlantid morphospecies. However, deeper genus level relationships were not resolved in this study, and it provided few clues about the longer-term evolutionary history of the family.…”

Abstract Background: The aragonite shelled, planktonic gastropod family Atlantidae (shelled heteropods) is likely to be one of the first groups to be impacted by imminent ocean changes, including ocean warming and ocean acidification. With a fossil record spanning at least 100 Million years (Ma), atlantids have experienced and survived global-scale ocean changes and extinction events in the past. However, the diversification patterns and tempo of evolution in this family are largely unknown. Results: Based on a concatenated maximum likelihood phylogeny of three genes (cytochrome c oxidase subunit 1 mitochondrial DNA, 28S and 18S ribosomal rRNA) we show that the three extant genera of the family Atlantidae, Atlanta, Protatlanta and Oxygyrus, form monophyletic groups. The genus Atlanta is split into two groups, one exhibiting smaller, well ornamented shells, and the other having larger, less ornamented shells. The fossil record, in combination with a fossil-calibrated phylogeny, suggests that large scale atlantid extinction was accompanied by considerable and rapid diversification over the last 25 Ma, potentially driven by vicariance events. Conclusions: Now confronted with a rapidly changing modern ocean, the ability of atlantids to survive past global change crises gives some optimism that they may be able to persist through the Anthropocene.

“…Seven of them have been recorded in the northeast Pacific (McGowan 1967, Seapy & Richter 1993, Cummings & Seapy 2009. However, there is genetic evidence that the species diversity worldwide is underestimated (Wall-Palmer et al 2018).…”

Atlantids are holoplanktonic snails found in epipelagic waters of all oceans mostly tropical and subtropical but some temperate. There are three genera within Atlantidae, which can be identified by a dextrally coiled, laterally flattened, transparent, discoid (Atlanta, Protatlanta) or involute (Oxygyrus) shell. They can be found in samples collected with plankton nets or sediment traps. Of the 23 species recognized worldwide, eight are known in the northeast Pacific. Herein distribution range extensions are reported for the atlantid species Atlanta oligogyra and Protatlanta souleyeti.
