Five new West Pacific species of the cusk-eel genus Neobythites (Ophidiidae) from the lower shelf and upper slope of the Solomon Sea, off Okinawa, Japan, and off Fiji are described. The descriptions are based on nine specimens from three fish collections and unvouchered fresh colour photographs showing three specimens taken shortly after being caug...
Coastal marine fish diversity from E India and Indonesia to S Japan is still insufficiently investigated. Of the 42 species of goatfishes (Mullidae) recorded from this area, 12 were described only since 2010 and ten of those belong to the genus Upeneus. During a recent review of species of Upeneus of the so-called japonicus-species group (character...
The main objectives of this study were to clarify the taxonomic status of Mulloides armatus, listed as incertae sedis in current taxonomic literature, and to examine the extent of phenotypic differentiation among subspecies and populations of the yellowstripe goatfish Mulloidichthys flavolineatus (Mullidae) in the Indo-Pacific. In total, 53 quantit...
The highly diverse goatfish genus Upeneus (Mullidae) requires enhanced attention regarding the possible occurrence of undescribed species in insufficiently explored regions. This study focuses on the South-Western Indian Ocean region (SWIO), and on the so-called japonicus-group, a taxonomic species group of Upeneus. Based on in-situ observations an...
For the goatfish genus Upeneus Cuvier 1829 (Mullidae), a new taxonomic species group called the “margarethae group” is established which can be distinguished from the six species of the most similar “tragula group” by a combination of the following characteristics: absence of dark pigmentation in the area of the first dorsal-fin tip, 21–25 total gi...
Goatfishes of the genus Parupeneus (Mullidae), from several areas and countries of the Indo-West Pacific, were studied, focusing on species characterized by a symmetrically rounded rear end of the maxilla, which belong to the so-called heptacanthus group. We examined 62 meristic and morphometric characters and colour patterns from 180 specimens fro...
This review was motivated by the recent collection of a specimen of the specious cuskeel genus Neobythites (Ophidiidae) off Myanmar and difficulties to identify it based on the available literature. This specimen has an ocellus consisting of a dark oval spot and a concentric white ring placed on the dorsal fin at mid-body, typical for many Neobythi...
For Jansen’s goatfish, Parupeneus jansenii (Mullidae), taxonomic knowledge has been rather poor and occurrence information restricted to a few localities only, with verified records from northern Sulawesi and Sunda Street (Indonesia), and Luzon (Philippines). This species is here included in the so-called “heptacanthus” group together with the Indo...
Two new goatfishes of the genus Upeneus (Mullidae) belonging to the putative japonicus species group are described and compared with congeneric species using a large set of meristic, morphometric and colour characters. Upeneus farnis n. sp. Uiblein & Peristiwady is described based on 14 adult specimens (> 65 mm SL) collected at the local fish marke...
The phenotypic, distributional, and genetic distinctiveness of the bandtail goatfish Upeneus taeniopterus within the genus Upeneus (Mullidae) is elaborated using a comprehensive alpha-taxonomic and barcoding approach. Based on a large number of morphometric, meristic and colour characters obtained from 71 preserved or freshly photographed specimens...
Phenotypic and genetic differentiation among goatfish species of the genus Upeneus which had been formerly included in the so-called ‘vittatus group’ were examined using a comprehensive alpha-taxonomic and barcoding approach. Four of the five species of this group, U. indicus, U. suahelicus, U. supravittatus and U. vittatus, occur in the Western In...
Upeneus lombok n. sp. is described from two specimens collected off Lombok, Indonesia, at depths of 54-76 m, and one subadult specimen from the local fish market at Tanjung Luar, Lombok. Four specimens of U. asymmetricus were collected at the same fish market representing the first record of the species since its description from two Philippine Isl...
A new goatfish, Upeneus torres sp. nov. (Mullidae), is described based on 27 specimens from Australia and Vanuatu using a diversified alpha-taxonomy approach that integrates species, population and size-related allometric differences. Based on large sets of comparative morphological and colour data, diagnoses and inter- and intraspecific comparison...
Currently, three of the seven described species of Sirembo Bleeker, 1858 and both species of Spottobrotula Cohen & Nielsen, 1978 are considered valid. The present revision is based on 73 specimens of Sirembo known from the Red Sea to Japan and southwards to off northwestern Australia and northern New South Wales and 19 specimens of Spottobrotula kn...
A new goatfish, Upeneus heemstra sp. nov. (Mullidae), from the Western Indian Ocean and SE India is described from initial DNA barcoding and quantitative morphological screening, followed by a taxonomic analysis featuring the comparison of 56 meristic, morphometric and colour characters compiled from 340 specimens of 10 phenotypically similar speci...
A new goatfish, Upeneus saiab n. sp. (Mullidae), is described from six specimens collected off Angoche, northern Mozambique, during a research cruise of the RV Dr. F. Nansen in August 2009.

The mullid genus Upeneus is highly diverse, with a considerable number of new species found only recently. Based on 16 specimens of Upeneus collected at the southeastern edge of the Seychelles Bank, a large oceanic platform in the Western Indian Ocean, a new species, Upeneus seychellensis, is described. Comparisons with and among populations of the...
Jan Mayen Island was already the focus of science during the First International Polar Year in 1882–1883, even though fish
biodiversity played only a minor role. Marine investigations were conducted at irregular intervals until the area was covered
by the routine research activities of the Institute of Marine Research (IMR). The objective of this p...
The number of species of the goatfish genus Upeneus from the western Indian Ocean has increased considerably due to recent taxonomic efforts. Here we describe a new species, Upeneus randalli n. sp., based on body and fin coloration and 50 morphometric and meristic characters of eight specimens from the Persian Gulf, and supported by comparative dat...

Oceanic islands of volcanic origin have a narrow shelf and a steep slope that should lead to considerable spatial overlap among coastal and oceanic fauna. During six pelagic surveys in the Canarian archipelago, Eastern Central Atlantic, over 65,000 fishes belonging to 211 species were collected at depths between 8 and 1035 in. The mesopelagic famil...
The cirrate octopod Stauroteuthis syrtensis is a mesopelagic species commonly collected in the North Atlantic. Individuals were observed at depths > 600 m and typically within 100 m of the bottom in three similar to 900 m deep canyons indenting the southern edge of Georges Bank. When first sighted, most octopods were floating passively with their w...

The systematics of the abyssal giant cusk-eel genus Spectrunculus was revised, based on the examination of 55 specimens recently collected from the northern Mid-Atlantic Ridge and 32 specimens from earlier collections in the Atlantic and Pacific Oceans. The conclusion of Nielsen and Hureau that only one sexually dimorphic species, S. grandis, exist...
This review investigates if goatfishes qualify as habitat indicators and play a role as key species for use in coastal ecosystem monitoring and management, emphasizing major gaps of knowledge in goatfish ecology and systematics. Currently, 66 species of goatfishes are known, the family occurring widely in tropical, subtropical and temperate habitat...
Deep-sea fishes show distinct behavioral responses to manned submersibles and remotely operated vehicles (ROV's). Here we provide preliminary evidence that such disturbance responses are mediated by a variety of factors including type of vehicle and environmental and species-specific constraints.
A total of 168 bottom longline operations were carried out at depths between 72 and 1102 m during four cruises off Lanzarote and Fuerteventura, Canary Islands. One hundred and twenty-eight operations were successful, resulting in the capture of 1167 fishes belonging to 55 species. Clear variations in fish total weight and number, species richness a...
Based on the examination of almost 1200 specimens representing 50 species of the secondary deep-sea fish genus Neobythites (family Ophidiidae), this study provides an overview of body coloration and a detailed comparison among species that have
typical ocelli or eyespots consisting of a dark spot surrounded by a contrasting pale ring on their dorsa...
This paper presents preliminary information on identification of midwater and demersal fishes to the lowest possible taxon, their spatial distribution and abundance patterns and their behaviour in four deep-water canyons. Data were collected with a manned submersible and an underwater video profiler. The basic study question was: “Does increased tr...
Much is known in very broad terms about the distribution of deep-sea fishes, but information on fine-scale habitat selection and behaviour in the largest living space on earth is still rare. Based on video sequences from 4 dives performed with the manned submersible 'Nautile' at depths between 400 and 2000 in in the Bay of Biscay, NE Atlantic, we s...
Based on the analysis of video sequences recorded during four dives with a manned submersible in the Bay of Biscay, NE Atlantic, evidence is provided that the northern cutthroat eel Synaphobranchus kaupi shows marked variations in abundance and in the adoption of three locomotion behaviours—forward movement, station holding, and drifting—among six...
Quantitative data collected with different bottom trawls at the Great Meteor Seamount (subtropical NE Atlantic, 30°N; 28.5°W) in 1967, 1970 and 1998 are compared. Bootstrap estimates of total catch per unit effort increased from 6.96 and 10.8 ind. m–1 h–1 in 1967 and 1970, respectively, to 583.98 ind. m–1 h–1 in 1998. Gear effects and an effect of...
Analyses of 13 submersible dives on the continental slope of the Bay of Biscay
(north-east Atlantic) showed that: (i) orange roughy formed dense aggregation of more than
4000 individuals per ha close to the bottom of a small underwater canyon. In all other study
areas only a few individuals were observed. Orange roughy aggregations are probably...
Morphological variation and ecological characteristics of habitats of two populations of the Pyrenean salamander Euproctus asper from the Flumen river, Prepyrenees, and the Salto del Pis torrent, Central Pyrenees, were studied to determine whether intraspecific differences in body form and sexual dimor- phism occur and if they can be functionally r...

... The cusk eel genus Neobythites Goode et Bean, 1885 is the most diverse group in the family Ophidiidae, with 60 species currently recognized as valid (Nielsen 2002;Nielsen et al. 2009;Ohashi et al. 2012;Uiblein and Nielsen 2018, 2021, 2023. Species of this genus are characterized by having a tapering caudal portion; operculum with one strong spine; pelvic-fin rays 2; medial basibranchial tooth patch 2; preopercle with 0 to 3 spines; snout length equal or longer than the width of eye window (Nielsen 2002). ...
... Similarly, individuals of the oreosomatid fish species, Neocyttus helgae, have been observed "holding station" perhaps in an effort to gain refuge from the currents as well as increase encounters with passing zooplankton (Auster et al., 2005). Several species of demersal fishes also were observed to be stationary and inactive in deep-water canyons off Georges Bank, suggesting that these fishes are either sit-and-wait predators, are avoiding predators, or conserving energy, all of which should be successful strategies for life in highly structured benthic habitats (Uiblein et al., 2005). Individuals of E. picta appear to have adopted similar strategies by remaining stationary at a fixed location on the corals where they function as sit-and-wait predators ready to capture prey from the ever-changing water column moved by high-speed currents while conserving their energy reserves. ...
