The Mexican Society of Cartilaginous Fishes A.C., in coordination with the Planetarium of Playa del Carmen SAYAB, invites to participate in the First Latin American Conference of Sharks, Rays and Chimaeras, and the VIII National Symposium of Sharks and Rays.
5th International Whale Shark Conference (IWSC5) from 28-31 May 2019
From 28-31 May 2019, the town of Exmouth in the Ningaloo Coast World Heritage Area will welcome delegates to the 5th International Whale Shark Conference (IWSC5), a meeting of the world’s leading whale shark scientists, conservationists, natural resource managers and tourism managers. This is the fifth such conference to be held, following on from the successful IWSC4 held in Doha, Qatar in 2016. This meeting is timed to showcase Ningaloo’s world’s best practice whale shark management program and will follow the Ningaloo Whaleshark Festival, an annual community event that celebrates these magnificent animals.
IWSC5 will bring together local scientists, researchers and postgraduate students to interact with international colleagues and collaborators to explore all aspects of whale shark biology and ecology and how this can translate to direct, on-ground conservation efforts. Delegates from around the world will be treated to four days of presentations, workshops, social functions and experiencing the world renowned Ningaloo whale shark tourism industry to forge new relationships and collaborations and debate ideas.
A core focus of IWSC5 will be bringing together end users of the science being presented, such as tourism managers, marine park managers and conservation groups. This will improve the uptake and application of research and help develop collaborations between research scientists and managers and industry.

EBERT, D.A. & VAN HEES, K.E. (2018): Etmopterus marshae sp. nov, a new lanternshark (Squaliformes: Etmopteridae) from the Philippine Islands, with a revised key to the Etmopterus lucifer clade. Zootaxa, 4508 (2): 197–210
New species: Etmopterus marshae
Abstract: A new species of lanternshark, Etmopterus marshae (Squaliformes: Etmopteridae), is described from the Philippine Islands, western North Pacific Ocean. The new species occurs along insular slopes at a depth range of 322–337 m. The new species resembles other members of the “Etmopterus lucifer” clade in having linear rows of dermal denticles, and most closely resembles E. burgessi from Taiwan and E. evansi and E. pycnolepis from the South Pacific. It can be distinguished from all other members of the E.lucifer clade by a combination of characteristics, including length of anterior and posterior flank branches being of relatively equal length, straight vs. curved anterior flank marking, relative lengths of caudal markings, coloration, and relatively small size. A revised key to the revised key to the Etmopterus lucifer clade is provided.

New genus: Cretacladoides, Natarapax
New species: Cretacladoides ogiveformis, Cretacladoides noricum, Natarapax trivortex
Abstract: Cladodontomorphii represents an archaic clade of chondrichthyan fishes characterised by distinct tooth morphologies referred to as the cladodont type. This group of cartilaginous fishes first occurred during the early Palaeozoic Era as revealed from the fossil record and were long thought to have gone extinct at the Permian-Triassic mass extinction event. However, a recently reported chondrichthyan tooth assemblage from the Early Cretaceous of France suggests that cladodontomorphs might have survived the catastrophic events at the Permian-Triassic boundary, probably by occupying deep-sea refuge environments. Here, we describe two new chondrichthyan genera based on isolated teeth recovered from Valanginian (Early Cretaceous) deep-water deposits of Austria, including a total of three new species tentatively assigned to the cladodontomorph families Falcatidae (Cretacladoides ogiveformis gen. et sp. nov. and C. noricum sp. nov.) and Ctenacanthidae (Natarapax trivortex gen. et sp. nov.). In addition, an enameloid microstructure analysis had led to the identification of a distinct multilayered enameloid including a parallel-, tangled-, and radial-bundled enameloid, whose phylogenetic distribution within Chondrichthyes is here discussed in detail, leading to the conclusion that the herein described cladodont-like taxa, together with those reported from the French Early Cretaceous might be closely related to ancient Palaeozoic taxa.

CUTMORE, S.C. & CRIBB, T.H. & YONG, R.Q.Y. (2018): Aporocotylids from batoid and elopomorph fishes from Moreton Bay, Queensland, Australia, including a new genus and species of blood fluke infecting the Giant shovelnose ray, Glaucostegus typus(Rhinopristiformes: Glaucostegidae). Parasitology International, 67 (6): 768-775
New genus: Ogawaia
New species: Ogawaia glaucostegi
Abstract: Fishes of the elasmobranch superorder Batoidea and the basal teleost superorder Elopomorpha were assessed for blood flukes (Digenea: Aporocotylidae) during a parasitological survey conducted in Moreton Bay, Queensland, Australia. A new blood fluke genus and species, Ogawaia glaucostegi n. gen., n. sp., is described from the Giant shovelnose ray, Glaucostegus typus (Anonymous [Bennett]) (Rhinopristiformes: Glaucostegidae). Ogawaia glaucostegi differs from species of all other aporocotylid genera in the combination of the absence of anterior caeca and oral sucker, having a pronounced distal oesophageal chamber, a strongly coiled testis and a common genital pore. The new species most closely resembles Myliobaticola richardheardi Bullard & Jensen, 2008, from which it differs in lacking an oral sucker and in possessing a straight (rather than coiled) oesophagus, longer caeca in proportion to the oesophageal and total body length, and a much longer testis relative to body length. Ogawaia glaucostegi is just the eighth aporocotylid described from chondrichthyans, of which four belong to monotypic genera. This is the first description of a blood fluke from the order Rhinopristiformes, and the first of a chondrichthyan-infecting aporocotylid from Australian waters. Elopicola bristowi Orelis-Ribeiro & Bullard, 2017 is reported from Australia for the first time, from the type-host, Elops hawaiensis Regan (Elopiformes: Elopidae). This species is identified by morphological and molecular data and distinctions between our specimens and those of the original description are discussed.
CANTATORE, D.M.P. & IRIGOITIA, M.M. & HOLZER, A.S. & BARTOSOVA-SOJKOVA, P. & PECKOVA, H. & FIALA, I. & TIMI, J.T. (2018): The description of two new species of Chloromyxum from skates in the Argentine Sea reveals that a limited geographic host distribution causes phylogenetic lineage separation of myxozoans in Chondrichthyes. Parasite, 25: 47
New species: Chloromyxum atlantoraji, Chloromyxum zearaji
Abstract: During a survey on the myxosporean fauna of Rajiformes from the Atlantic coast of Argentina, in waters off Buenos Aires Province (34–42S; 53–62W), the gall bladders of 217 specimens belonging to seven species of skates, representatives of two families, were examined. As a result, three species of Chloromyxum Mingazzini, 1890, namely C. atlantoraji n. sp., C. zearaji n. sp. and C. riorajum Azevedo, Casal, Garcia, Matos, Teles-Grilo and Matos, 2009 were found infecting three endemic host species, the spotback skate Atlantoraja castelnaui (Arhynchobatidae), the yellownose skate Zearaja chilensis (Rajidae) and the Rio skate Rioraja agassizii (Arhynchobatidae), respectively. These species were described based on myxospore morphology and morphometry characterization, as well as by providing their small subunit ribosomal DNA (SSU rDNA) sequences. The SSU rDNA-based phylogenetic analyses showed that these three species constituted a well-established monophyletic subclade within the marine Chloromyxumclade, while branches subtending the other Chloromyxum species were poorly resolved or unresolved, independently of the host taxonomic identities (Carchariniformes, Myliobatiformes, Orectolobiformes, Pristiophoriformes, Rajiformes, Squaliformes and Torpediniformes) and/or host geographic distribution (Atlantic coast of Portugal, Atlantic coast of the USA, Australian waters or Mediterranean Sea). The possible causes of these discrepancies are discussed, providing new insights into the phylogeny of the marine Chloromyxum clade.
DEDRICK, E.A. & REYDA, F.B. & IWANYCKYJ, E.K. & RUHNKE, T.R. (2018): Two new species of Stillabothrium (Cestoda: Rhinebothriidea) from stingrays of the genus Fontitrygon from Senegal. Folia Parasitologica, 65: 014
New species: Stillabothrium allisonae, Stillabothrium charlotteae
Abstract: Morphological and molecular analyses of cestode specimens collected during survey work of batoid elasmobranchs and their parasites in Senegal revealed two new species of the rhinebothriidean cestode genus Stillabothrium Healy et Reyda 2016. Stillabothrium allisonae Dedrick et Reyda sp. n. and Stillabothrium charlotteae Iwanyckyj, Dedrick et Reyda sp. n. are both described from Fontitrygon margaritella (Compagno et Roberts) and Fontitrygon margarita (Günther). Both new cestode species overlap in geographic distribution, host use and proglottid morphology, but are distinguished from each other, and from the other seven described species of Stillabothrium, on the basis of their pattern of bothridial loculi. Phylogenetic analyses based on sequence data for 1,084 bp from the D1–D3 region of 28S rDNA that included multiple specimens of both new species and eight other species of Stillabothrium corroborated the morphologically-determined species boundaries. The phylogenetic analyses indicate that S. allisonae sp. n. and S. charlotteae sp. n. are sister species, a noteworthy pattern given that the two species of the stingray genus Fontitrygon they both parasitise, F. margaritella and F. margarita, are also sister species. Although species of Stillabothrium vary widely in their patterns of facial loculi, the variation does not appear to correlate with phylogeny. Most species of Stillabothrium parasitise myliobatiform elasmobranch genera of the Dasyatidae Jordan. This study brings the number of described species of Stillabothrium to nine, three of which occur in the eastern Atlantic, two of which occur off the northern coast of Australia, and four of which are from coastal Borneo.

Introducing Otlet: An online database to search for and share research samples
In the life sciences, acquiring biological samples can be challenging and costly. The resulting small sample sizes may jeopardise a study’s statistical power, experimental design and publication potential. Sharing leftover samples is a great way to build collaboration, but too often these valuable items are left in freezers and forgotten. Scientists may not be aware that their samples could be useful to someone in a different country, or may simply have no idea how to connect with interested parties.
If you are looking to collaborate, share, and boost sample sizes in your current study, the solution is here. Otlet is a free platform that allows scientists to connect and share their biological samples with others. Launched in June 2018, Otlet is not a tissue bank, but a communication hub for facilitating sample-sharing directly between scientists.
Otlet accepts records for all sample types and all plant and animal species. As an expanded version of our previous platform, Shark Share Global, Otlet has a large number of records for sharks and rays. We have also upgraded the software, added new features, and made it even easier to upload sample records.
What can you do with Otlet?
Submit. Simply lodge a record of your unused, shareable research sample onto the database using our quick, <4-minute process.
Search. Browse the database of over 13,000 records to find specific species and sample types.
Enquire. Contact the sample holder directly to discuss sharing options and shipping arrangements.
Request. Can’t find the sample you need? Post a list of your criteria to the searchable database so others know what you are looking for. Requests for samples are also emailed out to Otlet users weekly.
What are the benefits of using Otlet?
Collaboration. Otlet connects you with researchers from across the globe, forming new links with people working in your field.
Efficiency. Valuable samples are used, not wasted—especially important when studying rare and endangered species.
Transparency. Key sharing criteria, such as authorship requirements and acknowledgement, are provided up-front by each user. There’s no cost and no obligation; sharing is at each person’s discretion.
Community. Sharing samples with researchers in developing and under-represented nations helps advance equity and diversity in science.

Getting a grip on the slow but unique evolution of sharks
- Date: October 8, 2018
- Source: RIKEN
- Summary: Scientists have decoded the whole genomes of two shark species for the first time and improved the whale shark genome sequences released previously. By analyzing the genomes and comparing them with those of other vertebrate species, they have constructed an overview of their unique life histories and evolutionary paths.
Satellite tech to create more effective, 'true' shark sanctuaries
- Date: October 16, 2018
- Source: University of California - Santa Barbara
- Summary: When they first set out to follow grey reef sharks around the Republic of the Marshall Islands (RMI), researchers intended to survey their movement in the protected waters there. What they found was a disturbing development for the Pacific island nation.
