- Etmopterus samadiae n. sp., a new lanternshark (Squaliformes: Etmopteridae) from Papua New Guinea
- A new species of lanternshark, Etmopterus samadiae (Squaliformes: Etmopteridae), is described from off northern Papua New Guinea, in the western Central Pacific Ocean. The new species resembles other members of the "Etmopterus lucifer" clade in having linear rows of dermal denticles and most closely resembles E. brachyurus from the western North Pacific. The new species occurs along insular slopes between 340 and 785 m depth. The new species can be distinguished from other members of the E. lucifer clade by a combination of characteristics, including length of anterior flank branch markings being slightly shorter than its posterior branch, a longer caudal base marking, and irregular and variable number of black, horizontal, dash-like marks on sides of body. Molecular analysis based on the NADH2 marker further supports the distinction of E. samadiae from other members of the E. lucifer clade. © 2017 Magnolia Press., Export Date: 12 April 2017, Article, Correspondence Address: White, W.T.; CSIRO Oceans and Atmosphere, GPO Box 1538, Australia; email: email@example.com, Funding details: ACIAR, Australian Centre for International Agricultural Research, Funding details: NSF, National Science Foundation, Funding text: The senior author was supported by a project on the shark and ray resources of Papua New Guinea funded by the Australian Centre for International Agricultural Research (ACIAR; project FIS/2012/102), CSIRO Oceans & Atmosphere, and the National Fisheries Authority (NFA).

- Preface: Feeding ecology of elasmobranchs
- Elasmobranchs are apical predators in most marine communities where they occur, often playing a substantial role in the food web dynamics of those communities. However, despite their high trophic status they are often poorly studied compared to most commercially important teleosts. Furthermore, despite efforts towards ecosystem-based management, elasmobranchs are still often lumped into generic categories referred to as "shark" or "skate" unclassified, with limited effort to identify individual species. The role of elasmobranchs in ecosystems has never been more important to our understanding of marine ecology due to high levels of exploitation of many species. Similar to other high trophic level predators, many elasmobranchs have life-history characteristics that make them vulnerable to over-exploitation. Elasmobranch populations are now heavily targeted in many fisheries throughout the world. Increasing exploitation of this group is especially alarming because their feeding ecology is poorly studied and by extension their influence in shaping ecosystems. Given recent increased attention on elasmobranchs in the scientific literature, management and conservation circles, and the general news media, researchers over the past decade have begun to more closely examine the ecological role of this important taxon of fishes. Due to this increasing awareness, and the development of new and innovative methods and analytical techniques, it prompted us to organize an international symposium on the "Feeding Ecology of Elasmobranchs". The symposium was held on 10 July 2010, in conjunction with the 27 th annual meeting of the American Elasmobranch Society meetings in Providence, Rhode Island. © 2012 Springer Science+Business Media B.V.
