A new species of pygmy squid, Idiosepius hallami n. sp., is described from eastern Australia. It differs I. notoides Berry, 1921 and pygmaeus Steenstrup, 1881 (also found in Australian waters) a number traits, including the club suckers, shape funnel-mantle locking apparatus modification male hectocotylus. Mitochondrial DNA markers (12S rRNA, 16S rRNA cytochrome c oxidase subunit 1) indicate that it also distinct on molecular level. The recognised as taxon Stradbroke I., Queensland for which...
Abstract Bobtail squid are emerging models for host–microbe interactions, behavior, and development, yet their species diversity distribution remain poorly characterized. Here, we combine mitochondrial transcriptome sequences with morphological analysis to describe three of bobtail (Sepiolidae: Sepiolinae) from the Ryukyu archipelago, compare them related taxa. One Ryukyuan type was previously unknown, is described here as Euprymna brenneri sp. nov. Another morphologically indistinguishable...
Cryptic species are common in the ocean, particularly among marine invertebrates such as octopuses. Delineating cryptic is problematic octopus taxonomy where plasticity recorded taxonomic characters often results low resolution at level. This study investigated morphological relationships seven phylogenetic clades (identified using cytochrome c oxidase subunit I) of broadly distributed Octopus vulgaris complex and close relatives. Morphological analyses this were successful delimiting O....
The Great Australian Bight (GAB) comprises the majority of Australia's southern coastline, but to date its deep water fauna has remained almost unknown. Recent issuing oil and gas leases in region highlighted this lack baseline biological data established a pressing need characterise benthic abyssal fauna. From 2013 2017, six large-scale systematic surveys GAB were conducted from 200 5000 m depth, constituting deepest sampling Australia. Sampling was on soft sediment hard substrates, both at...
Abstract Based on a comprehensive analysis of molecular sequence data, the Sepiidae genera Acanthosepion Rochebrune, 1884; Ascarosepion Aurosepina Jothinayagam, 1987; Decorisepia Iredale, 1926; Doratosepion Rhombosepion 1884 and Spathidosepion are here re-instated formally recognised as valid. Sepia Linnaeus, 1758 Sepiella Gray, 1849 retained, but Metasepia Hoyle, 1885 is placed in alternative combination with . The subgenus Digitosepia Lipiński, 2020 well supported herein elevated to...
All records of crustaceans, molluscs, polychaetes, echinoderms and fishes from Sydney Harbour were extracted the Australian Museum database, plotted onto a map that was divided into four regions. Records analysed according to number species, genera families present over 3000 species recorded, approximately double triple found in neighbouring Hawkesbury River, Botany Bay Port Hacking. We examined rate accumulation time since 1860s, which followed stepwise pattern usually correlated with...
Vampyroteuthis infernalis Chun, 1903, is a widely distributed deepwater cephalopod with unique morphology and phylogenetic position. We assessed its habitat trophic ecology on global scale via stable isotope analyses of collection beaks from 104 specimens the Atlantic, Pacific Indian Oceans. Cephalopods typically are active predators occupying high level (TL) exhibit an ontogenetic increase in δ15N TL. Our results, presenting first comparison for deep-sea invertebrate, demonstrate that V....
Post-mortem drift is a common phenomenon within living shelled cephalopods (Nautilidae, Sepiidae and Spirulidae) has led to the misinterpretation of geographical ranges in some species. In this study, distributional reliably identified cuttlefish beach-collected sepions (cuttlebones) from Australian Museum, Museum Victoria Art Gallery Northern Territory collections were compared determine extent sepion drift. 12 24 species examined, distributions dry extended beyond currently known...
The subfamily Gymnonereidinae (sensu Fitzhugh, 1987) is represented in Australian waters by 14 species seven genera, of which five are new and these described: Ceratocephale aureola n.sp., C. setosa Gymnonereis minyami G. yurieli n.sp. Nicon rotunda Six records for waters. This nereidids characterised the lack chitinous pharyngeal papillae, although soft papillae may be present. A key to subfamilies family Nereididae given together with a genera Gymnonereidinae. paper represents first series...
Two species of Onychophora (Peripatopsidae) were previously known to occur in the south-western corner Western Australia: Occiperipatoides occidentalis (Fletcher, 1895) and gilesii (Spencer, 1909).These two taxa occupy geographically disjunct regions.Using morphological characters, 'occidentalis' is shown comprise a species-complex; three are described here, which new.A new genus, Kumbadjena, erected for O. reflect significant molecular differences between members this complex gilesii.The...
Examination of specimens Sepioloidea d'Orbigny, 1845, from northern Australia led to the discovery a new species.It is described here as magna sp.nov.It distinguished other nominal species, S. lineolata (Quoy & Gaimard, 1832) and pacifica (Kirk, 1882), by its size, number tentacular club suckers, absence obvious colour pattern modification hectocotylus.
Based on two beachwashed cuttlebones, Sepia mestus Gray, 1849 was described in a single sentence. The whole animal remained largely unknown until partial descriptions were published by Adam and Rees (1966) Lu (1998). Though well known scuba divers as the ‘Common Sydney Cuttlefish’, or ‘Red Cuttle’, lack of an adequate description scientific literature has made identification comparison with other species difficult. discovery some supposed S. South China Sea (Khromov 1987) prompted...
Examination of specimens Euprymna Steenstrup.1887 from northern Australia led to the discovery a new species.It is described here as pardalota sp.nov.It distinguished all but one other nominal species (E.phenax Voss, 1962) in having two rows suckers on arms, rather than four rows.It differs E. phenax number traits, including: possession large spots over most body, shape funnel organ, modification hectocotylus, and spermatophore length structure.In addition, among Australian Museum collection...
Despite less than perfect oceanic conditions generated by tropical cyclone Debbie in 2017, a field team from the Australian Museum Research Institute sampled marine invertebrates multiple habitat types around Lord Howe Island. Collections were made during two weeks March–April 2017 intertidal sand-flats and reefs, subtidal habitats using SCUBA. Hand collecting was supplemented with limited use of traps. Protocols emphasized fixation preservation methods that favour molecular approaches to...
Examination of specimens Sepiella Cray, 1849, from northern Australia led to the discovery a second species in addition weberi Adam, 1939, already known occur region.This is described here as mangkangunga sp.nov., and redescribed types Australian material.The two species, while occupying narrow geographic range, were collected at different depths.Sepiella found between 77-88 m waters (though type Indonesia 18 m, surface), S. sp.nov.occurs shallow water, 1.1 3.3 m.
Examination of the Stoloteuthis maoria (Dell, 1959) type specimens held in Museum New Zealand, Te Papa Tongarewa revealed that two female paratypes were not conspecific with S. holotype male and belong to genus Iridoteuthis Naef, 1912. Based on this finding, is redescribed here properly define characters. Its occurrence Australian waters formally recognised for first time; species was known previously only from Zealand. The taxon found be new described as I. merlini, n. sp. Like maoria,...
Despite the absence of cuttlefish in Aotearoa New Zealand waters, cuttlebones and cuttlebone fragments have been reported collected country since early twentieth century. Not all could be reliably identified. As such, here we review material from shores available natural history collections, as well literature online records. Species were identified, through morphological features and, for first time, DNA barcoding, as: Australian endemic Sepia apama Gray, 1849 Gray JE. 1849. Catalogue...
