Another new discoverd shark species! OPEN ACCESS!
Angel sharks (genus Squatina) are small- to medium-sized sharks with flattened bodies, that live on the seafloor. Until now, 23 valid species of angel sharks have been identified around the world, of which over half are thought to be facing a moderate to severe risk of extinction. Several juvenile angel sharks were collected by researchers working on the Mascarene Plateau, an elevated area of seabed in the Indian Ocean, in 1988 and 1989. They appeared different in coloration and in body shape and structure to a species known from East Africa and Madagascar, the African angel shark. Additional angel sharks were caught off the western coast of India in 2016 and in the central western Indian Ocean in 2017, including adult individuals. Information on body measurements and skeleton structure were collected, and genetic analyses were also conducted on these sharks and on museum specimens previously identified as African angel sharks. The results indicated that the specimens collected from the Mascarene Plateau and off southwestern India were a species that is new to science. It is genetically and morphologically distinct from the African angel shark; is smaller when born and when fully grown; and lives in a distinctly different area. The newly described species has been named Lea’s angel shark.

Upcoming Meetings:


Indo-Pacific Fish Conference and the Australian Society for Fish Biology

20-24 November 2023, Auckland, New Zealand
Keep me updated

We look forward to welcoming you to the University of Auckland, located in the heart of Auckland city.  We invite you to come and meet the people that live and work here, explore our beautiful city and hope that you leave with lasting friends, partnerships and memories.

The Organising Committee look forward to welcoming you to the 11th Indo-Pacific Fish Conference (IPFC) and Annual Conference of the Australian Society for Fish Biology, to be held 20-24 November 2023 at the University of Auckland, New Zealand.

The Indo-Pacific Fish Conference (IPFC), held every four years, is undoubtedly one of the world’s premier ichthyological conferences and is eagerly anticipated by marine, estuarine and freshwater fish enthusiasts alike.

The Australian Society for Fish Biology (ASFB), founded in 1971, aims to promote research, education and management of fish and fisheries across the Indo-Pacific.

We are excited to bring these two conference together in a joint meeting that will reflect the extraordinary biological, environmental and cultural diversity of the vast Indo-Pacific region.

Auckland is a modern city offering a variety of cultural experiences, accommodation and entertainment options for every taste and budget. The city is a key regional hub, with transport connections to multiple cities across New Zealand, Australia, the Pacific and beyond.

The University of Auckland is an internationally recognised university that provides outstanding conference facilities and conference support within easy walking distance of the city centre. An exciting programme of conference field trips will allow attendees to sample the diversity of regional marine and freshwater ecosystems. Before or after the conference, delegates could explore Auckland’s magnificent Hauraki Gulf and its beautiful islands. The jewel of the gulf is Waiheke Island, a haven of vineyards, olive groves, beaches and fine dining, just a 40-minute ferry ride from downtown Auckland. For an exciting day trip, discover the history and sandy coves of Rotoroa Island, explore the open wildlife sanctuary of Tiritiri Matangi Island or climb the volcanic cone of Rangitoto Island for incredible views from the summit. If you have a little more time, travel south for a summer holiday to discover the majestic Milford and Doubtful Sounds, encounter marine life in Abel Tasman National Park, enjoy New Zealand’s beautiful Bay of Islands, or maybe plan a field trip or tropical holiday on one of the many Pacific islands that are only a short flight away from Auckland.

We look forward to welcoming you to Auckland in 2023!

Annual conference


94th Annual Meeting of the Palaeontological Society (PalGes) in Jena, 18.-22.9.2023

From Early Life to the Neandertals

For the first time since founding of the Palaeontological Society (PalGes) in Greifswald 1912 the annual meeting takes place in Jena. This is only the second time in Thuringia since the 1925 meeting in Weimar. We, from the Institute of Geosciences (IGW) at the Friedrich Schiller University of Jena, are glad to invite the members of the Society to our city at the river Saale. The city is a special location, stretching along the river, which is carving into a Muschelkalk plateau with Buntsandstein outcropping below. The surrounding Muschelkalk heights provide marvellous sights over the city. Our institute is located on the slope of the Hausberg in the eastern part of Jena. It was re-founded 1992 and still grows with an increasing number of scientists. Jena houses the most important university of Thuringia and is also a flourishing economic centre with companies like ZEISS and SCHOTT, it is popular for its touristic sights and a wide range of restaurants. The Thuringian palaeontology has a long tradition and is famous for fossils from the Permian, Triassic and Quaternary. We can offer a diverse range of excursions covering fossil sites from the late Palaeozoic to the Quaternary. The organisation of the meeting is supported by colleagues from Thüringischer Geologischer Verein (TGV), Stiftung Schloss Friedenstein Gotha, Museum Schloss Bertholdsburg Schleusingen, Research Station of Quaternary Palaeontology Weimar, and Phyletical Museum Jena. We are looking forward to welcome you in Jena and hear your presentations at 94. Annual Meeting of the PalGes in Jena!

White Sharks Global

Port Lincoln, South Australia, Australia

Sunday 12th to Friday 17th of November 2023


The organising committee is pleased to announce the upcoming White Sharks Global conference (Sunday 12th – Friday 17th of November 2023) in Port Lincoln, South Australia, home of the world’s first white shark tourism industry.
White Sharks Global is the first international white shark conference in 13 years and will provide a forum for the white shark community and stakeholders to meet, share ideas, and update information and report on recent scientific studies. This conference and associated workshops will facilitate in-depth discussions of key challenges related to white sharks.
For more information visit: whitesharksglobal.com and follow @WhiteSharksGlob or contact info@whitesharksglobal.com
The last white shark-focused conference was in Hawaii 13 years ago in early 2010 and a lot has research and studies have happened since. 
We have planned for five days of conference, with one day free in the middle to allow for a dive trip to the Neptune Islands Group Marine Park. There will be several focused workshops (e.g., supporting the recovery of white shark populations, supporting the management of white shark tourism, managing human-shark conflict), contributed talk sessions (5- and 15-min talks), and poster sessions. Based on previous events and our survey, we are expecting ~150 attendants from across the globe, including research scientists, students, resource managers, public safety officials, wildlife tourism operators, environmental consultants, natural history-based production companies, and television network representatives from countries all over the world such as South Africa, United States, Australia, Mexico, New Zealand, and Canada.

Weigmann, S. & Vaz, D.F.B. & Akhilesh, K.V. & Leeney, R.H. & Naylor, G.J.P. (2023) Revision of the Western Indian Ocean Angel Sharks, Genus Squatina (Squatiniformes, Squatinidae), with Description of a New Species and Redescription of the African Angel Shark Squatina africana Regan, 1908. Biology, 12(7), Article 975
New species: Squatina leae
Abstract: Sampling efforts on the Saya de Malha Bank (part of the Mascarene Plateau, western Indian Ocean) unveiled three unusual small juvenile angel shark specimens, that were a much paler color than the only known western Indian Ocean species, Squatina africana Regan, 1908. However, it took many years before further specimens, including adults of both sexes, and tissue samples were collected. The present manuscript contains a redescription of S. africana based on the holotype and additional material, as well as the formal description of the new species of Squatina. All specimens of the new species, hereafter referred to as Squatina leae sp. nov., were collected in the western Indian Ocean off southwestern India and on the Mascarene Plateau at depths of 100–500 m. The new species differs from S. africana in a number of characteristics including its coloration when fresh, smaller size at birth, size at maturity, and adult size, genetic composition, and distribution. Taxonomic characteristics include differences in the morphology of the pectoral skeleton and posterior nasal flap, denticle arrangement and morphology, vertebral counts, trunk width, pectoral–pelvic space, and clasper size. A key to the species of Squatina in the Indian Ocean is provided.

New species: Heterodontus marshallae
Abstract: A new species of hornshark is described from northwestern Australia based on six whole specimens and a single egg case. Heterodontus marshallae n. sp. was previously considered to be conspecific with H. zebra from the Western Pacific. The new species differs from H. zebra in the sequence of its NADH2 gene, several morphological characters, egg case morphology and key coloration features. Despite the coloration being similar between H. marshallae n. sp. and H. zebra, i.e., pale background with 22 dark brown bands and saddles, they differ consistently in two key aspects. Firstly, the snout of H. marshallae n. sp. has a dark semicircular bar, usually bifurcated for most of its length vs. a pointed, triangular shaped dark marking in H. zebra. Secondly, H. zebra has a dark bar originating below the posterior gill slits and extending onto anterior pectoral fin, which is absent in H. marshallae n. sp. The Heterodontus marshallae n. sp. is endemic to northwestern Australia and occurs in deeper waters (125–229 m) than H. zebra (0–143 m).

Stumpf, S. & Kettler, C. & Kindlimann, R. & Cuny, G. & Kriwet, J. (2023) The oldest Gondwanan record of the extinct durophagous hybodontiform chondrichthyan, Strophodus from the Bajocian of Morocco. Swiss Journal of Palaeontology, 142, Article 5
New species: Strophodus atlasensis
AbstractStrophodus is a speciose and geographically widespread taxon of large durophagous hybodontiform chondrichthyan, with a stratigraphic range extending from Middle Triassic to the Early Cretaceous. Here, we describe a new species of StrophodusSatlasensis sp. nov., based on an incomplete articulated dentition recovered from marine Bajocian deposits of the eastern High Atlas Mountains in Morocco. The new species is diagnosed by a unique combination of dental characters that includes, among others, the presence of triangular first lateral teeth, mesio-distally wide and bulbous second lateral teeth without an occlusal crest or dome and uniquely shaped first posterior teeth that are shorter mesio-distally than being labio-lingually long, as well as small second posterior teeth whose roots protrude below the crowns to meet each other in an efficient interlocking manner. The holotype and only specimen of Strophodus atlasensis sp. nov. represents the hitherto oldest known record of Strophodus from Gondwana and the first record of that genus from the Bajocian, thus adding valuable novel information to our incomplete understanding of the evolutionary history of extinct hybodontiform chondrichthyans.

New genus: Terangabatis, Atlantobatis, Sowibatos
New species: Ptychotrygon nazeensis, Terangabatis thiami, Rhinobatos popenguinensis, Atlantobatis acrodonta, Sowibatos minimus, Dasyatis reticulata, Coupatezia casei, Phosphatodon cretaceus,
Abstract: Three successive horizons were sampled by bulk-sampling across the Campanian–Maastrichtian marine succession at the Cap de Naze cliff, South of Popenguine, Senegal. The material collected includes several hundreds of elasmobranch micro-remains as well as surface-collected specimens that are described in the present work. Twenty-six species are recorded, including three new genera and eight new batomorph species (Ptychotrygon nazeensis sp. nov., Terangabatis thiami gen. et sp. nov., ‘Rhinobatos’ popenguinensis sp. nov., Atlantobatis acrodonta gen. et sp. nov., Sowibatos minimus gen. et sp. nov., ‘Dasyatis’ reticulata sp. nov., Coupatezia casei sp. nov., Phosphatodon cretaceus sp. nov.). These new samplings complement previous records based on surface collection of the Cape de Naze section and bring the number of elasmobranch species for this fauna to 31. Increasing elasmobranch taxonomic diversity throughout the three successive assemblages indicates a transition from restricted marine to open coastal settings. This high-diversity fauna is dominated by necto-benthic batomorphs and is similar in its structure to other Tethyan and Eastern Atlantic Maastrichtian faunas. The high number of species apparently endemic to the studied area suggests high habitat differentiation in corresponding marine Maastrichtian settings. The presence of typical Maastrichtian species in the top of Unit 1 argues against a Campanian age previously proposed for this unit, while our data support a middle–late Maastrichtian age for the ferruginous sandstone bed of Unit 3.
Duffin, C.J. & Heckert, A.B. & Hancox, P.J. (2023) A new low diversity lacustrine elasmobranch fauna from the Lower Triassic Burgersdorp Formation of South Africa with descriptions of Lissodus tumidoclavus n. sp. (Chondrichthyes: Hybodontoidea). Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, 308(2), 151–169
New species: Lissodus tumidoclavus
Abstract: Hybodont chondrichthyans are known from both marine and freshwater assemblages and are globally widespread throughout the Palaeozoic and Mesozoic. However, the dynamics of their diversity before and after the Permo-Triassic extinction are not well understood, as both Late Permian and Early Triassic assemblages are rare, and most assemblages are known from Laurasia. The chondrichthyan fauna of the Early Triassic Langbergia-Garjainia subzone, Cynognathus Assemblage Zone from the farm Driefontein 11, Free State, South Africa, is described for the first time. A new species, Lissodus tumidoclavus n. sp. is established from these freshwater lacustrine deposits, which also include teeth assignable to Polyacrodus n. sp. and a third taxon left in open nomenclature. The new species of Lissodus is the most abundant at Driefontein, represented by hundreds of small (≤ 2.5 mm crown length) teeth from multiple tooth positions and a jaw fragment preserving 14 teeth in four tooth families. Defining characteristics include a vertical ridge along a labial peg that has strong nodes on either its flanks or at the crown-root junction. Specimens of Polyacrodus sp. are rarer (n < 100), larger (up to 4 mm length) and more robust, and the unnamed morphotype is the rarest (n ≤ 25). Like other Early Triassic freshwater chondrichthyan faunas, the Driefontein elasmofauna comprises a low diversity suite of small-sized hybodontiform sharks and may represent a case of reduced diversity and size (“Lilliput effect”) in the aftermath of the end-Permian extinction event.

About the position

A three-year PhD fellowship in molecular ecology is available at the Faculty of Biosciences and Aquaculture (FBA), Nord University Bodø, Norway. For the right candidate a four-year position, which also includes 25% teaching, supervision and/or administrative duties, may be possible.

Increasing anthropogenic disturbance of marine ecosystems is leading to loss of keystone species. Fisheries are probably the most important contemporary pressure on natural populations in the marine environment, yet supply vital protein. The selective focus of intensive commercial fisheries demonstrably alters life-history traits. You will use advanced novel genomic approaches to explore the impact of fisheries on spurdog, Squalus acanthias. This study promises unprecedented resolution of population genetics, movement patterns, population estimates, seascape genomics, and genomic footprint of over-fishing.

The position will be available from 1st of January 2024 at the Bodø Campus.

Shark shock: Scientists discover filter-feeding basking sharks are warm-bodied like great whites

Date: July 20, 2023
Source: Trinity College Dublin
Summary: Approximately 99.9% of fish and shark species are 'cold-blooded', meaning their body tissues generally match the temperature of the water they swim in -- but researchers have just discovered the mighty basking shark is a one-in-a-thousand exception. Instead, these sharks keep the core regions of their bodies warmer than the water like the most athletic swimmers in the sea such as great white sharks, mako sharks and tuna.

Tiny scales reveal megalodon was not as fast as believed, but it had a mega-appetite explaining its gigantism

DePaul University professor leads discovery of prehistoric shark's intriguing lifestyle
Date: July 11, 2023
Source: Taylor & Francis Group
Summary: A new study reveals the iconic extinct Megalodon, or 'megatooth shark', was a rather slow cruiser that used its warm-bloodedness to facilitate digestion and absorption of nutrients.


Estimating the long-term effects of whale shark feeding practices

Date: July 3, 2023
Source: Flinders University
Summary: Increasing opportunities for up-close encounters with sharks and other animals are making wildlife tourism one of the fastest growing tourism sectors -- leading ecology experts to venture to one of the world's main sites to investigate the effects of tourism on endangered whale sharks. At Oslob in the Philippines, Flinders University's Southern Shark Ecology Group and Global Ecology Lab joined local Filipino researchers to measure how the daily feeding regimes for resident whale shark population might have affected their behaviour and physiology by assessing their activity and metabolic requirements.
