The term Elasmobranchs or chondrichthyans refers to the The great majority of the commercially important species of group of marine organisms with a skeleton made of cartilage. chondrichthyans are elasmobranchs. The latter are named They include sharks, skates, rays and chimaeras. These for their plated gills which communicate to the exterior by organisms are characterised by and differ from their sister 5–7 openings. In total, there are about 869+ extant species group of bony fishes in the characteristics like cartilaginous of elasmobranchs, with about 400+ of those being sharks skeleton, absence of swim bladders and presence of five and the rest skates and rays.

The chondrichthyans which are placed in Class of the relationships and identity of different organisms. Elasmobranchii are grouped into two main subdivisions Classification of elasmobranchs certainly does not evade this Holocephalii (Chimaeras or ratfishes and elephant fishes) process, and species are sometimes lumped in with other with three families and approximately 37 species inhabiting species, or renamed, or assigned to different families and deep cool waters; and the Elasmobranchii, which is a large, other taxonomic groupings. It is certain, however, that such diverse group (sharks, skates and rays) with representatives revisions will clarify our view of the taxonomy and phylogeny in all types of environments, from fresh waters to the bottom (evolutionary relationships) of elasmobranchs, leading to a of marine trenches and from polar regions to warm tropical better understanding of how these creatures evolved.

Dans ce travail, nous rapportons la capture d’un chien de mer pointe de flèche, Deania pro f u n d o ru m (Smith & Radcliffe, 1912), dans les eaux portugaises méridionales. Le spécimen, une grande femelle mature de 87,5 cm de longueur totale, n’avait que quatre fentes branchiales du côté droit, sans présenter de cicatrice à l’en- droit où la cinquième fente aurait dû se situer. Des mesures compa- ratives entre les tailles des fentes branchiales gauches et droites amènent à conclure que la fente manquante est probablement la première.

Identification Guide to the Deep-Sea Cartilaginous Fishes Of
Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean FAO. 2015. Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean. FishFinder Programme, by Ebert, D.A. and Mostarda, E., Rome, Italy. Supervision: Merete Tandstad, Jessica Sanders (FAO, Rome) Technical editor: Edoardo Mostarda (FAO, Rome) Colour illustrations, cover and graphic design: Emanuela D’Antoni (FAO, Rome) This guide was prepared under the “FAO Deep–sea Fisheries Programme” thanks to a generous funding from the Government of Norway (Support to the implementation of the International Guidelines on the Management of Deep-Sea Fisheries in the High Seas project) for the purpose of assisting states, institutions, the fishing industry and RFMO/As in the implementation of FAO International Guidelines for the Management of Deep-sea Fisheries in the High Seas. It was developed in close collaboration with the FishFinder Programme of the Marine and Inland Fisheries Branch, Fisheries Department, Food and Agriculture Organization of the United Nations (FAO). The present guide covers the deep–sea Southeastern Atlantic Ocean and that portion of Southwestern Indian Ocean from 18°42’E to 30°00’E (FAO Fishing Area 47). It includes a selection of cartilaginous fish species of major, moderate and minor importance to fisheries as well as those of doubtful or potential use to fisheries. It also covers those little known species that may be of research, educational, and ecological importance. In this region, the deep–sea chondrichthyan fauna is currently represented by 50 shark, 20 batoid and 8 chimaera species. This guide includes full species accounts for 37 shark, 9 batoid and 4 chimaera species selected as being the more difficult to identify and/or commonly caught.

Greeneye Spurdog, Squalus Chloroculus
Published Date: 1 March 2019 Greeneye Spurdog, Squalus chloroculus Report Card Recovering assessment IUCN Red List IUCN Red List Australian Endemic to Australia Global Near Threatened Assessment Assessment Assessors Walker, T.I. Management measures are expected to rehabilitate depleted Report Card Remarks populations Summary The Greeneye Spurdog is a large, deepwater endemic dogfish from southeast Australia. The species has low biological productivity due to its high longevity and low reproductive output. Fishing was intense in some Source: CSIRO National Fish Collection. License: CC BY Attribution areas where it has caused severe population reductions. Fishing intensity has since reduced, and management measures such as a low combined Total Allowable Catch of all deepwater dogfish in southeast Australia and a network of refuges have stabilised the population. The management actions are expected to rehabilitate the population. Therefore, the Greeneye Spurdog is assessed as Near Threatened (IUCN) and Transitional Recovering (SAFS). Distribution The Greeneye Spurdog occurs off southern Australia from New South Wales (NSW) to the Great Australian Bight (Last and Stevens 2009). Stock structure and status The Greeneye Spurdog is a recently described species (Last et al. 2007). The relative abundance of populations has varied widely across its distribution range with localised depletion in some localities and comparatively high abundance in others (Walker and Gason 2007). Declines in the population indicated by both fishery-dependent monitoring and fishery-independent scientific surveys show that Greeneye Spurdog is vulnerable to rapid population decline where it is heavily fished. Fisheries The primary threat to the Greeneye Spurdog is fishing. Fishing is intensive on trawl grounds around southeast Australia, where there is evidence that this species has been severely depleted in some localities, but less so in others.

Tropical Eastern Pacific Records of the Prickly Shark, Echinorhinus Cookei
Tropical Eastern Pacific Records of the Prickly Shark, Echinorhinus cookei (Chondrichthyes: Echinorhinidae)1 Douglas J. Long,2,3,5 John E. McCosker,3 Shmulik Blum,4 and Avi Klapfer4 Abstract: Most records of the prickly shark, Echinorhinus cookei Pietschmann, 1928, are from temperate and subtropical areas of the Pacific rim, with few rec- ords from the tropics. This seemingly disjunct distribution led some authors to consider E. cookei to have an antitropical distribution. Unreported museum spec- imens and underwater observations of E. cookei from Cocos Island, Costa Rica; the Galápagos Islands; and northern Peru confirm its occurrence in the trop ical eastern Pacific and, combined with other published records from the eastern Pacific, establish a continuous, panhemispheric eastern Pacific distribution. The genus Echinorhinus contains two spe- Mundy [1994] and Crow et al. [1996]); it has cies, the bramble shark, E. brucus (Bonnaterre, subsequently been collected or observed off 1788), from the Atlantic, Mediterranean, Japan (Taniuchi and Yanagisawa 1983, Ko- western Indian Ocean, and Australia, New bayashi 1986), Taiwan (Teng 1958), Palau Zealand, and Japan, and the prickly shark, (Saunders 1984), Tonga (Randall et al. 2003), E. cookei Pietschmann, 1928, known from New Caledonia (Fourmanoir 1979), New Hawai‘i and the western and eastern Pacific Zealand (Garrick 1960, Garrick and More- Ocean (Compagno et al. 2005, Last and Ste- land 1968), northeastern and southeastern vens 2009).

Sensitive to fishing pressure with some catches in Australia but Report Card Remarks uncertainty over stock status Summary The Leafscale Gulper Shark is a deepwater dogfish with a global distribution. Its flesh and livers are marketed in varying quantities over much of the species' range. Most targeted fishing pressure is in the northeast Atlantic where it is an important component of deepwater fisheries and declines of Source: CSIRO National Fish Collection. License: CC BY Attribution >80% have been reported. Catches of the species off Australia are relatively low and do not represent a significant component of deepwater catches. However, significant declines in closely related species in southeast Australia led to management measures to promote recovery of deepwater dogfish populations, such as catch limits and a ban on trawling below 700 m. The Leafscale Gulper Shark has intrinsically very low productivity, evident in significant population declines where it is heavily fished. Therefore, the species is assessed as globally Vulnerable (IUCN) and in Australia, Undefined Stock (SAFS) because the information is uncertain and insufficient to assess the Australian fish stock status. Distribution The Leafscale Gulper Shark occurs sporadically in the eastern Atlantic (Iceland to South Africa), in the Indian Ocean (South Africa and the Aldabra Islands), and the western Pacific (Japan, Taiwan, Philippines, Indonesia, New Zealand and Australia); a recent capture off the Galapagos Island extended the range to the eastern central Pacific (Acuna-Marrero et al.
