Abstract: Due to advances in fish-finding equipment and vessel capabilities, commercial and recreational fishers are now regularly accessing deep waters off the edge of the continental shelf and catching fish species that are rarely encountered in shallower waters or that have not previously been caught. This study details the capture of two Japanese rubyfish (Erythrocles schlegelii) in deep, offshore waters on the south coast of Western Australia, and in waters further south than previously encountered. This study also provides the first age estimates from counts of growth (opaque) zones in sectioned sagittal otoliths. The estimated ages of 8 years for both in iduals, one female and the other male, are much lower than what would have been expected based on age estimates for this species derived from scales undertaken in an earlier study. Understanding the biological characteristics of these deepwater fish species will assist in future management of these resources.

Abstract: Studies of sexual selection in monogamous species have hitherto focused on sexual selection among males. Here, we provide empirical documentation that sexual selection can also act strongly on females in a natural population with a monogamous mating system. In our field-based genetic study of the monogamous Western Australian seahorse, Hippoc us subelongatus , sexual selection differentials and gradients show that females are under stronger sexual selection than males: mated females are larger than unmated ones, whereas mated and unmated males do not differ in size. In addition, the opportunity for sexual selection (variance in mating success ided by its mean squared) for females is almost three times that for males. These results, which seem to be generated by a combination of a male preference for larger females and a female-biased adult sex ratio, indicate that substantial sexual selection on females is a potentially important but under-appreciated evolutionary phenomenon in monogamous species.

Abstract: A 9-year-old girl was reviewed by a tertiary ophthalmology service after being hit in her right upper eyelid by a fish whilst swimming. Initial wound exploration demonstrated fish scales in the wound. She was first treated conservatively with washout of the 5-mm wound and was discharged with oral ciprofloxacin. Five days later, the patient re-presented with a worsened ptosis due to periorbital swelling. Ultrasound of the upper lid demonstrated a foreign body in the upper lid. The patient was taken to theatre and, with the assistance of intraoperative ultrasound, the jaws of a needle fish were removed from the upper lid. The case highlights the importance of ultrasound and its intraoperative utility in cases of trauma and a suspicion of retained foreign bodies as well as the potential danger of fish injuries off the West Australian coast.

Abstract: The capture of a rarely encountered Randall's snapper Randallichthys filamentosus (female, 587 mm fork length) from the upper continental slope (c. 350 m) off the south coast of Western Australia (c. 34·5° S 122·5° E) in January 2014 represents its first record from the temperate Indian Ocean and a southern range extension. This record suggests that spawning of this predominantly tropical species may probably be occurring in the eastern Indian Ocean, considering the extensive, and unlikely, distance the progeny would have otherwise travelled from its typical distribution in the western and central Pacific Ocean.

Abstract: A new genus and two new species of miniature clingfishes are described based on specimens collected from dense stands of macroalgae in intertidal and shallow subtidal areas along the coast of southern Australia. The new genus, Barryichthys , is distinguished from other genera of the Gobiesocidae by unique features of the adhesive disc, including elongate papillae in adhesive disc regions A and B, the reduction and/or loss of several elements of the cephalic lateral line canals, the lower gill arch skeleton, and the neurocranium, and by having two distinct types of pectoral-fin rays. Barryichthyshutchinsi is described based on 19 specimens (12.4–18.7 mm SL) from Western Australia and South Australia. Barryichthysalgicola is described based on 22 specimens (9.0–21.0 mm SL) from Victoria, New South Wales and Tasmania. The new species are distinguished from each other by characters of body and head shape, vertebral counts, and aspects of live colour pattern. The new genus shares several characters in common with Parvicrepis , another genus of miniature gobiesocids from southern Australia that also inhabits macroalgae habitats. The many reductions and novel characters of Barryichthys are discussed within the context of miniaturisation.

Abstract: A new species of deep-water epinephelid fish is described from the west coast of Australia based on 14 specimens, 99-595 mm standard length. Hyporthodus griseofasciatus sp. nov. is endemic to Western Australia from Barrow Island to Two Peoples Bay in depths of 76-470 m. It has a series of eight grey bands alternating with eight brown bands along the body and the soft dorsal, soft anal and caudal fin margins are pale cream to white. It is distinguished from its nearest congener, H. ergastularius, by the presence of a star-like pattern of radiating lines on the head versus an overall brownish colour in the latter as well as significant differences in the quantitative analyses of 25 morphological characters. The two species have allopatric distributions on either side of the Australian continent. H. griseofasciatus is distinguished from H. octofasciatus by several grey bands being distinctly narrower than other grey bands (vs. all grey bands subequal in the latter) and the presence of broad white margins on the dorsal, caudal and anal fins (vs. narrow or absent in the latter). Some scale counts appear to also differ. Analyses of mitochondrial cytochrome oxidase subunit 1 sequences revealed reciprocally monophyletic clades with fixed differences and genetic distances typical of recently erged species of fishes.

Abstract: Australian species of the anthiadine genera Plectranthias and Selenanthias are reviewed. Twenty-two species of Plectranthias and two species of Selenanthias are recorded from Australian waters: Plectranthias sp. 1 from a seamount north of Middleton Reef and Norfolk Ridge, Tasman Sea P. alleni Randall from off southwest Western Australia P. azumanus (Jordan & Richardson) from off southwest Western Australia P. bennetti Allen & Walsh from Holmes Reef, Coral Sea P. cruentus Gill & Roberts from Lord Howe Island, and possibly off Stradbroke Island, Queensland P. ferrugineus n. sp. from the North West Shelf and Arafura Sea P. fourmanoiri Randall from Christmas Island and Holmes Reef, Coral Sea P. grahami n. sp. from off central New South Wales, Tasman Sea P. inermis Randall from Christmas Island P. japonicus (Steindachner) from the Arafura Sea and North West Shelf P. kamii Randall from the Coral Sea, Lord Howe Island and Christmas Island P. lasti Randall & Hoese from the North West Shelf and off Marion Reef, Queensland P. longimanus (Weber) from the Timor Sea, Great Barrier Reef, Coral Sea and southern Queensland P. maculicauda (Regan) from southeastern Australia P. mcgroutheri n. sp. from the North West Shelf P. megalophthalmus Fourmanoir & Randall from northeast of the Whitsunday Islands, Queensland P. melanesius Randall from southeastern Queensland and a seamount north of Middleton Reef P. moretonensis n. sp. from off Stradbroke Island, Queensland P. nanus Randall from the Cocos (Keeling) Islands, Christmas Island, Great Barrier Reef and Coral Sea P. retrofasciatus Fourmanoir & Randall from the Great Barrier Reef P. robertsi Randall & Hoese from off Queensland, Coral Sea P. winniensis (Tyler) from the Great Barrier Reef and Coral Sea Selenanthias analis Tanaka from the North West Shelf and Arafura Sea and S. barroi (Fourmanoir) from west of Lihou Reef, Coral Sea. Five of the species represent new records for Australia: P. azumanus, P. kamii, P. megalophthalmus, P. melanesius and S. barroi. Previous records of P. megalophthalmus from the North West Shelf are based on misidentified specimens of P. lasti. Records of P. wheeleri from the North West Shelf are based on specimens here identified as P. mcgroutheri n. sp. A record of P. yamakawai Yoshino from Christmas Island is based on a misidentified specimen of P. kamii. Plectranthias retrofasciatus was previously recorded from the Great Barrier Reef as P. pallidus Randall & Hoese, here shown to be a junior synonym of P. retrofasciatus. Video-based records of P. kelloggi from the Great Barrier Reef appear to be based on P. retrofasciatus. Identification keys, diagnoses, character summaries, photographs and Australian distribution information are presented for all species. Full descriptions are provided for the new species and for those newly recorded from Australia.

Abstract: Rising temperatures and extreme climate events are propelling tropical species into temperate marine ecosystems, but not all species can persist. Here, we used the heatwave-driven expatriation of tropical Black Rabbitfish ( Siganus fuscescens ) to the temperate environments of Western Australia to assess the ecological and evolutionary mechanisms that may entail their persistence. Population genomic assays for this rabbitfish indicated little genetic differentiation between tropical residents and vagrants to temperate environments due to high migration rates, which were likely enhanced by the marine heatwave. DNA metabarcoding revealed a erse diet for this species based on phytoplankton and algae, as well as an ability to feed on regional resources, including kelp. Irrespective of future climate scenarios, these macroalgae-consuming vagrants may self-recruit in temperate environments and further expand their geographic range by the year 2100. This expansion may compromise the health of the kelp forests that form Australia’s Great Southern Reef. Overall, our study demonstrates that projected favourable climate conditions, continued large-scale genetic connectivity between populations, and diet versatility are key for tropical range-shifting fish to establish in temperate ecosystems.

Abstract: The phenomenon of male pregnancy in the family Syngnathidae (seahorses, pipefishes, and sea dragons) undeniably has sculpted the course of behavioral evolution in these fishes. Here we explore another potentially important but previously unrecognized consequence of male pregnancy: a predisposition for sympatric speciation. We present microsatellite data on genetic parentage that show that seahorses mate size-assortatively in nature. We then develop a quantitative genetic model based on these empirical findings to demonstrate that sympatric speciation indeed can occur under this mating regime in response to weak disruptive selection on body size. We also evaluate phylogenetic evidence bearing on sympatric speciation by asking whether tiny seahorse species are sister taxa to large sympatric relatives. Overall, our results indicate that sympatric speciation is a plausible mechanism for the ersification of seahorses, and that assortative mating (in this case as a result of male parental care) may warrant broader attention in the speciation process for some other taxonomic groups as well.

Abstract: Scolopsis meridiana n. sp., described from 30 specimens collected from northern Australia, is closely related to S. taenioptera, both species having a dorsal scaled area on the head extending anteriorly to between the anterior margin of the eye and anterior nostril, the upper part of the pectoral-fin base with a reddish blotch when fresh, and lacking a small antrorse spine below the eye. However, the new species is distinguished from the latter by having two bands across the snout dorsum (vs. one band in S. taenioptera), 18–20 diagonal lines on the lateral body surface below the lateral line (diagonal lines absent), the posterior nostril horizontally elongated (vertically elongated), a deep caudal-peduncle and short pre-dorsal-fin length. Scolopsis meridiana is distributed in northern Australia, whereas S. taenioptera occurs in Southeast Asia. Two geographic populations of S. taenioptera (Philippines and remaining Southeast Asian region) are recognized following morphological and genetic analyses.

Abstract: Understanding the drivers of dispersal among populations is a central topic in marine ecology and fundamental for spatially explicit management of marine resources. The extensive coast of Northwestern Australia provides an emerging frontier for implementing new genomic tools to comparatively identify patterns of dispersal across erse and extreme environmental conditions. Here, we focused on the stripey snapper (Lutjanus carponotatus), which is important to recreational, charter-based and customary fishers throughout the Indo-West Pacific. We collected 1,016 L. carponotatus s les at 51 locations in the coastal waters of Northwestern Australia ranging from the Northern Territory to Shark Bay and adopted a genotype-by-sequencing approach to test whether realized connectivity (via larval dispersal) was related to extreme gradients in coastal hydrodynamics. Hydrodynamic simulations using CONNIE and a more detailed treatment in the Kimberley Bioregion provided null models for comparison. Based on 4,402 polymorphic single nucleotide polymorphism loci shared across all in iduals, we demonstrated significant genetic sub ision between the Shark Bay Bioregion in the south and all locations within the remaining, more northern bioregions. More importantly, we identified a zone of admixture spanning a distance of 180 km at the border of the Kimberley and Canning bioregions, including the Buccaneer Archipelago and adjacent waters, which collectively experiences the largest tropical tidal range and some of the fastest tidal currents in the world. Further testing of the generality of this admixture zone in other shallow water species across broader geographic ranges will be critical for our understanding of the population dynamics and genetic structure of marine taxa in our tropical oceans.

Abstract: Four polymorphic microsatellite loci were used to assess biological parentage of 453 offspring from 15 pregnant males from a natural population of the Western Australian seahorse Hippoc us angustus. Microsatellite genotypes in the progeny arrays were consistent with a monogamous mating system in which both females and males had a single mate during a male brooding period. Multilocus genotypes implicated four females in the adult population s le as contributors of eggs to the broods of collected males, but there was no evidence for multiple mating by females. Based on genotypic data from the progeny arrays, two loci were linked tightly and the recombination rate appeared to be approximately 10-fold higher in females than in males. The utility of linked loci for parentage analyses is discussed.

Abstract: Bio ersity conservation and management requires surveillance that captures the full spectrum of taxa. Here, we showcase the potential for a portfolio of visual, extractive, and molecular methods for detecting previously hidden components of tropical fish bio ersity in an economically and culturally valuable marine site that spans a tropical‐temperate ecotone—the Ningaloo Coast World Heritage Area. With scale and practicality in mind, we demonstrate how environmental DNA (eDNA) methods deployed in a stratified s ling design can yield a more comprehensive monitoring program for species presence than current alternatives (e.g., extractive s ling via anesthetic). eDNA from filtered water s les detected up to six times as many cryptobenthic fish species per site than s les collected with anesthetic, indicating it is a potentially powerful tool for assessing bio ersity of tropical fishes. However, there were also species that were only found when using anesthetic and the contribution of cryptobenthic species to overall ersity of the fish assemblage was unexpectedly low, suggesting not all cryptobenthic fish species have been detected with eDNA. There were also distinct differences in cryptobenthic assemblages both among sites and s le depths (2–3 m) when using eDNA from filtered water, suggesting this technique may be able to identify fine scale spatial differences in cryptobenthic fish assemblage. eDNA collected from water detects the most cryptobenthic species and is therefore an efficient tool for rapidly assessing bio ersity, but extractive techniques may still be required for biological and monitoring studies, and when combined with eDNA s ling provides the most comprehensive assessment of cryptobenthic fishes.

Abstract: The discovery and identification of species is fundamental to the documentation, conservation and management of bio ersity. The taxonomy of the antitropical Pseudocaranx dentex complex (Carangidae) is confused and inconsistently reported. Previous morphological analyses concluded that this complex consisted of three species, namely P. sp. ‘dentex’, P. georgianus and P. dinjerra, in Australian waters. This study used genetic (COI sequence) and morphological data to evaluate the validity of this conclusion. The COI data showed the presence of three discrete lineages within this complex, which appear to correspond to the above-mentioned three species. They also suggested that P. sp. ‘dentex’ is closely related to, and possibly the same species as, P. dentex from southern Africa and the Mediterranean Sea. Also, the extent of morphological and geographical overlap between P. georgianus and P. dinjerra was greater than previously documented which, uncorrected, could lead to identification errors and present challenges for monitoring and management of harvested stocks of these species. By answering important taxonomic questions, our results will facilitate the proper interpretation of the results of past studies and the design of future studies of the P. dentex complex. They have also highlighted the value of molecular data for identifying species in morphologically conservative taxa.

Abstract: The enigmatic blind cave eel Ophisternon candidum is one of Australia’s least known fishes and is one of only three vertebrates in Australia with an entirely subterranean existence. For more than half a century, O. candidum was thought to be restricted to some 100km of coastal cave systems in north-western Australia. Herein we report on two new populations, each separated by hundreds of kilometres, and provide the first complete list of all known records of subterranean Ophisternon in Western Australia. Using morphological and molecular data, we show that these populations are conspecific, with one population showing evidence of genetic differentiation. Geological and biogeographic explanations are explored, along with conservation considerations. All populations face actual and potential threats, especially from mining activities, and there is a need for management and conservation strategies specific to each population.

Abstract: Genetic monogamy is the rule for many species of seahorse, including the West Australian seahorse Hippoc us subelongatus . In this paper, we revisit mark-recapture and genetic data of H. subelongatus , allowing a detailed characterization of movement distances, home range sizes and home range overlaps for each in idual of known sex, paired status (paired or unpaired) and body size. As predicted, we find that females have larger home ranges and move greater distances compared to males. We also confirm our prediction that the home ranges of pair-bonded in iduals (members of a pair known to reproduce together) overlap more on average than home ranges of randomly chosen in iduals of the opposite or same sex. Both sexes, regardless of paired status, had home ranges that overlapped with, on average, 6–10 opposite-sex in iduals. The average overlap area among female home ranges was significantly larger than the overlap among male home ranges, probably reflecting females having larger home ranges combined with a female biased adult sex ratio. Despite a prediction that unpaired in iduals would need to move around to find a mate, we find no evidence that unpaired members of either sex moved more than paired in iduals of the same sex. We also find no effect of body size on home range size, distance moved or number of other in iduals with which a home range overlapped. These patterns of movement and overlap in home ranges among in iduals of both sexes suggest that low mate availability is not a likely explanation for the maintenance of monogamy in the West Australian seahorse.

Abstract: Marine macroinvertebrates support important fisheries throughout the Indo-Pacific, but stocks of species such as trochus (Rochia nilotica) are easily overharvested. In north-western Australia, trochus are taken from inshore reefs by Indigenous Australians and oceanic reefs by artisanal Indonesian fishers. The management of these environmentally distinct regions relies on understanding their spatial interdependencies, yet connectivity between them has not been evaluated empirically. Here, we used genotype-by-sequencing analysis of 514 trochus s les collected from 17 locations (15 in the inshore Kimberley, 2 offshore oceanic sites). Analysis of 5428 polymorphic single nucleotide polymorphism loci revealed significant genetic sub ision between the oceanic and coastal sites, and a subset of loci exhibited significantly higher sub ision, suggesting they are subject to directional selection. Population differentiation was also evident between the two oceanic sites, but not between coastal sites. Trochus populations from the coastal Kimberley and oceanic reefs represent two genetically and demographically independent units, with preliminary evidence for local adaptation to these distinctive environments. Management strategies for R. nilotica reflect these isions, but the limited connectivity among oceanic populations indicates that they are vulnerable to overexploitation. Furthermore, their potential adaptive distinctiveness indicates that coastal stocks may be unsuitable for replenishing oceanic stocks.
