Abstract:

Squatinids are quite distinct from other shark-like fishes, but individual species are difficult to differentiate. Four of the 16 known, valid squatinid species occur in the western North Pacific (WNP). Differences among the WNP species complex have traditionally relied upon the nasal barbel shape, interorbital and interspiracle distances, ocellus patterns, number of dermal folds about the mouth, and the presence of midback thorns. Unfortunately, many of these characters are difficult to distinguish, hindering identification of individuals. Using WNP squatinid specimens and photographs, both from field expeditions and museums, we confirm the validity of four species in the area. Additionally, we correct mistakes made in the literature on S. formosa type material, clarify differences in the particularly challenging distinction between S. formosa and S. nebulosa, and provide the basis for a revised dichotomous key for the region that includes all four known valid WNP squatinid species.

Abstract:

Four species of angel sharks (family Squatinidae) occur in temperate and subtropical Australian waters. Two of these, Squatina albipunctata sp. nov. and S. pseudocellata sp. nov., which occur mainly off subtropical eastern and western Australia respectively, are formally described and illustrated. The new species differ from temperate Australian species, S. australis and S. tergocellata, in morphometrics, meristics, squamation, and coloration. Another new angel shark, S. legnota sp. nov. from eastern Indonesia, is compared to these species. Unlike Australian Squatina, it has unfringed (rather than fringed) barbels on its nasal flap.

Abstract:

A detailed redescription of a chondrocranium from the basal Boom Clay Formation (Rupelian, Upper Oligocene) at the SVK clay pit, Sint-Niklaas (province of Oost-Vlaanderen, Belgium), previously assigned to the sawshark Pristiophorus rupeliensis, is presented. The chondrocranium is re-identified as that of an angel shark (Squatinidae), based on comparative anatomy of extant Squatina, inclusive of CT scans of Squatina africana, S. australis, S. dumeril, S. guggenheimand S. squatina, with different geographic distributions and representing all four angel shark clades as defined in a previous molecular study. Differential characters for chondrocrania listed in earlier accounts to discriminate angel shark species from the southwest Atlantic proved to be even more revealing when comparing angel sharks from different regions/clades. Despite this wide interspecific variation, the fossil chondrocranium compares well with modern Squatina, but differs in having a UUU-shaped ventral margin of the occipital region and rounded margins of the upper postorbital processes. The distal expansion of the upper postorbital processes present in modern species has not yet been observed in extinct squatinoids and might constitute a derived character for modern representatives only. Angel shark teeth and vertebrae are well known from the same basal deposit at the SVK clay pit, but Cenozoic squatinid taxonomy remains problematic. It is here discussed in detail for the Oligocene taxa S. angeloides, S. rupeliensisand S. beyrichi. For the time being, all SVK material is left in open nomenclature and referred to as Squatinasp.

Abstract:

AbstractFive new species of the genus Eudactylina are described based on specimens recovered from the branchial lamellae of six species of Japanese elasmobranchs. These are E. musteli nov. sp. from Mustelus griseus Pietschmann, 1908 (Triakidae), E. squatini nov. sp. from Squatina japonica Bleeker, 1858 (Squatinidae), E. dasyati nov. sp. from Dasyatis akajei (Müller & Henle, 1841) and Taeniura meyeni Müller & Henle, 1841 (Dasyatidae), E. taeniuri nov. sp. from T. meyeni, and E. gymnuri nov. sp. from Gymnura japonica (Temminck & Schlegel, 1850) (Gymnuridae). The males of four new species and the copepodid stages IV and V of E. gimnuri nov. sp. are described. Segment formation of the abdomen in the late copepodid stages of this genus and a peculiar process of the 1st endopodal segment of the male leg 2 are discussed.

Abstract:

A new species of angel shark, Squatina caillieti sp. nov., is described from a single specimen collected in deepwater off Luzon in the Philippines. The new species is closest to S. formosa and S. nebulosa, but differs from its congeners based on the following characters: unfringed barbels with rod-like tips, upper lip arch semi-oval in shape, large papillae present on the inside posterior margin of the spiracles, a greater interspiracle space than interorbital space, pelvic fin-tips which reach the first dorsal origin, a short pelvic fin base, short pelvic inner margin very short, and a short pelvic posterior margin; pelvic girdle span more than 1.4 times greater than head length; dorsal fins angular, greater interdorsal space than dorsal caudal space; caudal fin lobed, very short upper postventral caudal margin. The new species is the only Squatina confirmed as occurring in the Philippines. We also comment on the biogeography of western North Pacific Squatina and provide a revised regional key to this group.

Abstract:

All three species of angelsharks that inhabit the Mediterranean Sea, Squatina aculeata Cuvier, 1829; Squatina oculata Bonaparte, 1840; and Squatina squatina (Linnaeus, 1758), are classified as Critically Endangered on the IUCN Red List of Threatened Species, since their populations have suffered severe decline and range reduction, mainly due to fishing pressure. The presently reported study aims to further update records of S. aculeata and S. oculata in the basin in order to achieve a clearer picture of their current status and geographical distribution. In this way, we were able to add a contribution to our knowledge about their biological characteristics. Records on the incidental capture and observation of specimens of S. aculeata and S. oculata between 2005 and 2022 were collected through the input of alerted professional fishermen, fisher amateurs, and specialist observers on fishery landings or on board in the context of specific surveying programs as well as of citizens’ science initiatives. Biological characters such as total length, total weight, sex, and maturity were determined whenever possible. A total of 18 S. aculeata and 34 S. oculata specimens were recorded. Data corroborate the current occurrence, which is almost rare, of these two Critically Endangered elasmobranchs from the central to the east part of the basin, revealing furthermore the presence of S. aculeata in Sardinian waters, in the western part of the basin. Data document the important habitats for both species existing in the Strait of Sicily, especially in the area around Malta, and confirm the occurrence of S. aculeata in the southern Aegean Sea. The current presence of both species is also established in Mediterranean Egyptian waters. Our study suggests the urgent need for a wider application and/or reinforcement of existing protection measures for these angelshark species and their habitat, including populations of the southern Mediterranean waters.

Abstract:

Electroreception is an ancient sense found in many aquatic animals, including sharks, which may be used in the detection of prey, predators and mates. Wobbegong sharks (Orectolobidae) and angel sharks (Squatinidae) represent two distantly related families that have independently evolved a similar dorso-ventrally compressed body form to complement their benthic ambush feeding strategy. Consequently, these groups represent useful models in which to investigate the specific morphological and physiological adaptations that are driven by the adoption of a benthic lifestyle. In this study, we compared the distribution and abundance of electrosensory pores in the spotted wobbegong shark (Orectolobus maculatus) with the Australian angel shark (Squatina australis) to determine whether both species display a similar pattern of clustering of sub-dermal electroreceptors and to further understand the functional importance of electroreception in the feeding behaviour of these benthic sharks. Orectolobus maculatus has a more complex electrosensory system than S. australis, with a higher abundance of pores and an additional cluster of electroreceptors positioned in the snout (the superficial ophthalmic cluster). Interestingly, both species possess a cluster of pores (the hyoid cluster, positioned slightly posterior to the first gill slit) more commonly found in rays, but which may be present in all benthic elasmobranchs to assist in the detection of approaching predators.

Abstract:

ABSTRACTA section of the Vitabäck Clays at Eriksdal in southern Sweden was sampled for vertebrate fossils. Large bulk samples were collected from three horizons, including two coquina beds, VC3 and VC11, and a silty clay bed, VC7. Shark teeth are very common and constitute the main portion of the vertebrate material discussed herein. The selachian tooth faunas are almost exclusively represented by hybodonts, although a single tooth from a neoselachian shark, Squatinidae indet., was recorded from one horizon (VC3). Hybodont species identified from the Vitabäck Clay samples include Egertonodus basanus, Hybodus parvidens and Parvodus rugianus. Hybodont remains, other than teeth, include five morphotypes of placoid scales, incomplete cephalic spines and fragmentary fin spines.Other fossil groups represented in the sieved residues from the bulk samples include bivalves, gastropods and bony fish. Together with the selachians, they indicate fluctuating palaeosalinities in the area. The lower coquina bed, VC3, includes taxa indicating mesohaline conditions while the composition of the fauna in the other coquina bed, VC11, suggests oligohaline settings. In bed VC7, the presence of amphibian remains and the rarity of selachian fossils indicate an even lower salinity. Palynomorphs from the basal part of the section, immediately below bed VC3, indicate an earliest Cretaceous (Berriasian) age.

Abstract:

Two species of genus Squatina were recorded off the coast of Senegal and Squatina oculata is the most commonly caught in the area. Adult males and females studied were over 820 and 890 mm total length (TL) respectively, with the largest male and the largest female recorded being 1450 mm and 1570 mm and weighed 37 kg and 39 kg respectively. The females were significantly heavier than the males. Size at birth was between 226 and 266 mm and weight at birth between 129 and 159 g. Weight of ripe oocytes ranged from 87·65 to 117·60 g (mean SD 101·73±&;8·65). Gestation lasts one year minimum. Squatina oculata is a lecithotrophic species. Counts of ripe oocytes, eggs, embryos and fully developed foetuses showed that ovarian fecundity is significantly higher than uterine fecundity. The former ranged from 8 to 20 (mean SD 12·04±5·80), the latter from 3 to 8 (mean SD 6·22±3·41). There is no relationship between size and the categories of fecundity. Adult males and females were more common than the other categories of specimens landed. Among adults, females were more numerous than males, mainly gravid specimens.

Abstract:

Hiu merupakan sumber daya perikanan sangat rentan terhadap usaha penangkapan yang berlebihan (over-eksploitasi). Eksploitasi hiu di Indonesia masih berlanjut hingga hari ini tanpa diimbangi dengan tata kelola dan manajemen yang mengarah pada perikanan berkelanjutan. Penelitian ini bertujuan untuk mengetahui tingkat pemanfaatan hiu dan mengidentifikasi jenis hiu yang didaratkan di PPS Cilacap berdasarkan status konservasi. Penelitian ini dilakukan pada bulan April-Mei 2015 di PPS Cilacap, Jawa Tengah. Metode yang digunakan dalam penelitian ini adalah deskriptif survey. Tingkat pemanfaatan dihitung dengan cara menghitung jumlah hasil tangkapan pada tahun tertentu terhadap nilai TAC (Total Allowable Catch) atau jumlah tangkapan yang diperbolehkan. Jumlah tangkapan yang diperbolehkan (JTB) tersebut adalah 80% dari potensi maksimum lestari (MSY). Pendugaan nilai MSY dianalisis menggunakan model surplus produksi Fox. Status konservasi hiu dianalisis berdasarkan hasil tangkapan hiu yang didaratkan di PPS Cilacap dibandingkan dengan daftar kategori konservasi International Union for Conservation of Nature (IUCN). Hasil penelitian menunjukkan bahwa hiu tertangkap dan didaratkan di PPS Cilacap pada bulan Februari-Mei 2015 terdiri dari 11 famili atau 30 spesies. Hasil tangkapan terdiri dari famili Alopiidae, Carcharhinidae, Squalidae, Hexanchidae, Lamnidae, Triakidae, Sphyrnidae, Squatinidae, Rhinidae, Centrophoridae, dan Chimaeridae. Hasil tangkapan tertinggi berasal dari famili Alopiidae (2.028 hiu) dan hasil tangkapan terendah berasal dari famili Chimaeridae (2 hiu). Tingkat pemanfaatan hiu yang didaratkan di PPS Cilacap pada tahun 2010-2014 berdasarkan model surplus produksi Fox adalah 24-81%. Sebagian besar dari jumlah tangkapan hiu mendarat di PPS Cilacap pada bulan Februari-Mei 2015 yang mencakup dalam kategori dari rentan (46,44%) dan hampir terancam (39,65%). Jenis hiu yang didaratkan di PPS Cilacap termasuk dalam kategori rawan adalah A. pelagicus, A. superciliosus, I. paucus, C. plumbeus, R. ancylostoma, I. oxyrinchus, N. acutidens, C. squamosus, C. longimanus, sedangkan jenis hiu yang termasuk dalam kategori hampir terancam adalah C. sorrah, C. falciformis, H. perlo, P. glauca, C. brevivina, C. amblyrhynchoides, G. cuvieri, C. leucas, H. griceus, C. albimarginatus.
