Skates exhibit a variety of manifestations of sexual dimorphism. However, this phenomenon has been poorly documented in deepwater species. New data on the sexual dimorphism of five species of deepwater skates from the North Atlantic Ocean are presented: Amblyraja jenseni, Bathyraja pallida, Bathyraja richardsoni, Rajella bigelowi, and R. kukujevi. These skates exhibit sexual dimorphism most frequently in interorbital width, disc length and width, length of the third gill slit, horizontal diameter of the orbit, length of the fifth gill slit, space between the first and fifth gill slits, length of the second dorsal fin base, mouth width, length and width of each lobe of the nasal curtain, distance from the snout to the center of anus, distance from the snout tip to the point of maximum disc width, length of the lateral fold, length of the orbit + spiracle (measured together), tail height at the pelvic fin tips, and the number of median thorns. -

Here we report the presence of group of gyrocotylidean cestodes, which represent a Gyrocotyle spp. from rarely-caught deep-sea chi- sister group of the true tapeworms (Eucestoda). These maeras collected in the North-East Atlantic, and unique, non-segmented cestodes have been known describe two new species: G. haffii n. sp. from the since the 1850s and multiple species and genera have bent-nose chimaera, Harriota raleighana Goode & been erected despite a general agreement that the Bean, and G. discoveryi n. sp. from the large-eyed delineation of species on the basis of morphology is rabbit fish, Hydrolagus mirabilis (Collett). Nuclear effectively impossible. Thus, in the absence of ribosomal sequence data were generated for individual molecular studies, the validity of gyrocotylid taxa parasites taken from different host species collected on different dates and from different localities and were combined with previously published sequences. -

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -
Constraints on the Timescale of Animal Evolutionary History
Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

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.
