In recent years Azorean fishermen reported the presence of the smalltooth sand tiger shark, Odontaspis ferox (Risso, 1810), a very rare demersal shark species, associated with insular shelves and slopes, with occasional incursions into shallow waters and of poorly known biology and ecology. There are fourteen new records of this species, between 1996 and 2014, captured by spearfishing, harpoons, hand lines, or entangled in fishing gear in the Azores. These records were analysed and complemented with fishermen interviews, providing new locations and new biological data for this species. Also, specimens photographs were studied and post-mortem analysis were carefully carried out in one individual.
This species is rare and captured only as bycatch in shallow waters. More detailed information on this species is critically needed in order to assess its conservation status and implement management guidelines. Bycatch statistics are crucial in this respect.

Please inform us about new upcoming meetings!


II Joint Congress on Evolutionary Biology – Montpellier 2018

ESEB is delighted to welcome you to the Second Joint Congress on Evolutionary Biology. Joint Congresses take place every six years and bring together four of the world's largest academic societies in the field of evolutionary biology: the European Society for Evolutionary Biology, the American Society of Naturalists, the Society for the Study of Evolution and the Society of Systematic Biologists. The first joint congress was in Ottawa, Canada in 2012. The current (i.e. second) will be held in Montpellier, France, on August 19-22 2018.


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.

ITANO, W.M. & LAMBERT, L.L. (2018): A new cochliodont anterior tooth plate from the Mississippian of Alabama (USA) having implications for the origin of tooth plates from tooth files. Zoological Letters, 4: 12
New genus: Arcuodus
New species: Arcuodus multicuspidatus
Background: Paleozoic holocephalian tooth plates are rarely found articulated in their original positions. When they are found isolated, it is difficult to associate the small, anterior tooth plates with the larger, more posterior ones. Tooth plates are presumed to have evolved from fusion of tooth files. However, there is little fossil evidence for this hypothesis.
Results: We report a tooth plate having nearly perfect bilateral symmetry from the Mississippian (Chesterian Stage) Bangor Limestone of Franklin County, Alabama, USA. The high degree of symmetry suggests that it may have occupied a symphyseal or parasymphyseal position. The tooth plate resembles Deltodopsisbialveatus St. John and Worthen, 1883, but differs in having a sharp ridge with multiple cusps arranged along the occlusal surface of the presumed labiolingual axis, rather than a relatively smooth occlusal surface. The multicusped shape is suggestive of a fused tooth file. The middle to latest Chesterian (Serpukhovian) age is determined by conodonts found in the same bed.
Conclusion: The new tooth plate is interpreted as an anterior tooth plate of a chondrichthyan fish. It is referred to Arcuodus multicuspidatus Itano and Lambert, gen. et sp. nov. Deltodopsisbialveatus is also referred to Arcuodus.

BERNÁRDEZ, E. (2018): Truyolsodontos estauni n. gen., n. sp., Truyolsodontidae, a new family of lamniform sharks from the Cenomanian of northern Spain. Annales de Paléontologie, in press
New family: Truyolsodontidae
New genus: Truyolsodontos
New species: Truyolsodontos estauni
Abstract: Truyolsodontos estauni n. gen., n. sp. is described based on fossil teeth from the middle and upper Cenomanian of northern Spain. The species Protoscyliorhinus magnus Landemaine, 1991 is withdrawn from the genus Protoscyliorhinus and placed in this new one. For the new genus, the new family Truyolsodontidae is proposed.
