On October 15, the Fishbase Sweden Symposium took place. This years topic: fishes at depth including two talks by shark scientists Sarah Viana and Nicolas Straube.
More information:

The theme for the 16th annual FishBase Symposium, held at the Swedish Museum of Natural History in Stockholm on the 15th of October 2018, was Fishes At Depth / Fiskar På Djupet, a reference to the deep sea. To learn more about the fishes of the deep sea and their adaptations, FishBase Sweden invited six experts who gave lectures on a range of topics. Imants G. Priede introduced us to the deep sea by presenting an overview of the deep sea and its inhabitants and the evolutionary history of the deep sea fauna, while Alan Jamieson showed us some in situ observations of the world’s deepest-living fishes. Fanny de Busserolles gave a brief introduction to the light conditions of the deep-sea environment and the visual adaptations of deep-sea fishes. Jan Yde Poulsen talked about recently discovered species from deep-sea habitats. Sarah Viana introduced us to the diversity and taxonomy of tropical deep-sea sharks and skates, and provided an outline of fish collections in Brazil. Nicolas Straube gave an introduction to the taxonomy of bioluminescent sharks and their interrelationships and evolution. A summary of the symposium in PDF format is available at the FishBase Sweden blog (http://artedi.nrm.se)
Recordings of the talks can be watched on Youtube:

We wish you all merry Christmas and a happy new year 2019!

Upcoming Meetings:


Save the date! 25. - 29. March 2019

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.

 Description of a new deep-water dogfish shark from Hawaii, with comments on the Squalus mitsukurii species complex in the West Pacific. ZooKeys, 798: 135–157
New species: Squalus hawaiiensis
Abstract: Dogfish sharks of the genus Squalus are small, deep-water sharks with a slow rate of molecular evolution that has led to their designation as a series of species complexes, with low between-species diversity relative to other taxa. The largest of these complexes is named for the Shortspine spurdog (Squalus mitsukurii Jordan & Snyder), a medium-sized dogfish shark common to warm upper slope and seamount habitats, with a putative circumglobal distribution that has come under investigation recently due to geographic variation in morphology and genetic diversity. The Hawaiian population of Squalus mitsukurii was examined using both morphological and molecular analyses, putting this group in an evolutionary context with animals from the type population in Japan and closely-related congeners. External morphology differs significantly between the Hawaiian and Japanese S. mitsukurii, especially in dorsal fin size and relative interdorsal length, and molecular analysis of 1,311 base pairs of the mitochondrial genes ND2 and COI show significant, species-level divergence on par with other taxonomic studies of this genus. The dogfish shark in Hawaii represents a new species in the genus, and the name Squalus hawaiiensis, the Hawaiian spurdog, is designated after the type location.

HERZOG, K.S. & JENSEN, K. (2018): Five new species of the tapeworm genus Anthocephalum (Rhinebothriidea: Anthocephaliidae) parasitizing a single species of Indo-Pacific stingray, and a revised diagnosis of the genus. Journal of Parasitology, 104 (5): 505-522
New species: Anthocephalum blairi, Anthocephalum gravisi, Anthocephalum haroldsoni, Anthocephalum mounseyi, Anthocephalum ruhnkei
Abstract: Five new species of the elasmobranch tapeworm genus Anthocephalum Linton, 1890(Rhinebothriidea: Anthocephaliidae Ruhnke, Caira and Cox, 2015) are described from the mangrove whipray, Urogymnus granulatus (Macleay) from the Solomon Islands and northern Australia. Anthocephalum blairi n. sp., Anthocephalum gravisi n. sp., Anthocephalum haroldsonin. sp., Anthocephalum mounseyi n. sp., and Anthocephalum ruhnkei n. sp. differ from one another and their congeners based on quantitative and qualitative features of the scolex and proglottid anatomy. Species boundaries recognized by these distinguishing morphological features are supported by a maximum likelihood phylogenetic analysis based on combined 18S rDNA and 28S rDNA (D1–D3) sequence data showing the new species as independent lineages among 13 of the 18 species of Anthocephalum described to date. Several morphological features (the possession of columns of vitelline follicles that are interrupted by the ovary, a uterus that does not extend to the anterior margin of the proglottid but stops short in the anterior region of the field of testes, proximal surfaces of the marginal loculi covered with acicular filitriches only throughout, or with gladiate spinitriches and acicular filitriches throughout, and proximal bothridial surfaces with gladiate spinitriches and acicular filitriches) are collectively exhibited by the 5 new species and have not been documented previously in other species of Anthocephalum. The genus is herein amended to reflect these features. Additionally, the replacement name Anthocephalum centrurum(Southwell, 1925Ruhnke, 1994 is reinstated as the valid name for the type species of the genus, Anthocephalum gracile Linton, 1890, with the latter being the junior secondary homonym of A. gracile (Wedl, 1855Ruhnke, 1994. The description of these new species increases the number of valid species of Anthocephalum from 18 to 23.

New species: Aloculibothrium dasyatii
Abstract: Aloculibothrium dasyatii n. gen. n. sp. is described from the spiral intestine of Dasyatis sephenForsskal, 1775 captured at Digha coastal waters, Bay of Bengal, India. This species is placed under the famil Onchobothriidae (Braun, 1900) and erected a new genus Aloculibothrium to accommodate this specimen. The body is 24.22–36.58 mm long and with 310–325 proglottids; scolex rectangular with two parts; anterior bearing four bothridia with paired bifurcated hooks, divided into inner and outer prong and posterior with fleshy collar. The cestode has been compared with all the existing twelve different valid genera under the family Onchobothriidae but to accommodate the present specimens a new genera Aloculibothrium is erected.

Deepwater Horizon oil spill's dramatic effect on stingrays' sensory abilities

Study first to measure physiological effects of crude oil on marine animals' olfactory system

Date: November 13, 2018
Source: Florida Atlantic University
Summary: Marine fishes rely on their sensory systems to survive. A study is the first to quantify the physiological effects of whole crude oil on the olfactory function of a marine vertebrate -- the Atlantic stingray. Results of the study, confirm that exposure to crude oil, at concentrations mimicking those measured in coastal areas following the Deepwater Horizon oil spill in 2010, significantly impaired olfactory function in the Atlantic stingray after just 48 hours of exposure.

How the devil ray got its horns

Biologists reveals origins of a distinctive fish feature

Date: November 29, 2018

Summary: If you ever find yourself staring down a manta ray, you'll probably notice two things right away: its massive fins and the two fleshy growths curling out of its head that give it the nickname 'devil ray.' A new study shows that these two very different features have the same origin -- a discovery that reflects an important lesson for understanding the diversity of life.
