Carbonara, P. & Bellodi, A. & Bottaro, M. & Deplano, G. & Mulas, A. & Neglia, C. & Niedermüller, S. & Prato, G. & Toomey, L. & Follesa, M.C. 2025 Insights Into the Ecomorphology of the Blue Shark (Prionace glauca) in the Adriatic Sea (Central Mediterranean Sea). Ecology and Evolution, 15, Article e72478

This study explores morphometric variation and its ecomorphological implications in the Mediterranean blue shark population using linear and geometric morphometric analyses. A total of 119 specimens (64 females, 55 males), spanning from juvenile (total lengths [TLs] 85.4–149.8 cm in females and 82.9–121.2 cm in males) to adult (TLs 150.4–333.1 cm in females and 133.2–206.8 cm in males) stages, were analysed through a set of 30 linear measurements. Linear morphometric analysis identified significant differences between the juvenile and subadult/adult groups, particularly in the anterior body region and pectoral fin measurements. Geometric morphometric results revealed that juveniles have a more heterocercal caudal fin shape, which transitions to a less heterocercal form in adults, with a proportionally larger ventral lobe. The first dorsal fin showed positive allometry, becoming higher. The observed ontogenetic differences could improve energy efficiency and manoeuvrability. This aligns with the diel vertical migrations (DVM) of larger individuals and their need for sustained swimming during long-distance migrations, as well as the enhanced manoeuvrability required by juveniles, notably for predator avoidance.

https://onlinelibrary.wiley.com/doi/10.1111/jfb.70227
Abstract: Peru hosts a diverse chondrichthyan fauna due to its unique oceanographic conditions, including the convergence of the Humboldt Current and the South Equatorial Current. Despite historical research on Peruvian chondrichthyans, taxonomic updates and conservation concerns warrant a revised checklist. This study provides an updated and systematic compilation of chimaeras, sharks and rays recorded in Peruvian waters, including marine and freshwater species. A total of 110 species were confirmed, comprising seven chimaeras, 56 sharks and 47 rays, categorised into 67 genera, 40 families and 13 orders. Several species previously listed for Peru were excluded due to unreliable records or taxonomic revisions. Additionally, we assess the commercial exploitation and conservation status of chondrichthyans, identifying species subject to national regulations and international trade under CITES. Our findings provide a comprehensive update on Peruvian chondrichthyan biodiversity, highlighting the need for continuous monitoring, taxonomic validation and conservation strategies to ensure their sustainable management.

Extinct Chondrichthyes:

Otero, R.A. (2025): New Paleogene records of cartilaginous fishes (Chondrichthyes) from central Chile, including the oldest lamnid diversity from the southeastern Pacific. PeerJ, 13, Article e19996
New species: Lethenia carranzaensis
Abstract: The Paleogene chondrichthyan diversity of the southern hemisphere is mostly known in Antarctica, southernmost South America and New Zealand, but records from the southeastern Pacific remain sparse to date. Among these, lamnid sharks (the lineage of the great white shark) are one of the scarcer groups in the southern hemisphere prior to the Eocene; moreover, their occurrences prior to the Neogene remained unreported in the southeastern Pacific. This contribution presents new Paleogene chondrichthyans recovered from two different horizons at Loanco, central Chile, including the first local records of lamnids, with the description of a new species of the genus Lethenia.

Sections of two geologic units were studied. These provided new teeth of chondrichthyans, as well as a single associated tooth set plus fragments of jaw cartilage and vertebrae. The material was taxonomically identified and compared with other local occurrences and other coeval assemblages from the southern hemisphere.

This research recognizes a lower Paleocene-lower Eocene assemblage including material referable to Palaeohypotodus sp., Megasqualus sp. and Hexanchidae indet., the latter being the oldest known record in the southwestern Pacific. In addition, material from upper Eocene-lower Oligocene levels include dental pieces referable to the lamnids Macrorhizodus praecursor Leriche, and to a new species, Lethenia carranzaensis sp. nov., the latter represented by an exceptional specimen preserving a dental set, mandibular cartilage and vertebrae. Although discrete, this fauna shows the presence of Paleocene- lower Eocene elements commonly present in Antarctica and the Austral Basin, suggesting a typical Weddellian distribution during that timespan. On the contrary, the presence of the genus Lethenia reinforces the evidence of vertebrate interchange with the north Atlantic between the upper Eocene—lower Oligocene, previously suspected by the shared presence of blochiid billfishes. Evidence of such marine interchange is also present during the late Paleocene, based on the previous reports of Palaeogaleus, Physogaleus, and Premontreia, genera with similar known geographic occurrences. The new records of Macrorhizodus and Lethenia also represent the oldest known record of Lamnidae in the southwestern Pacific, proving its early presence previous to its widespread and abundant occurrence during the Neogene.

(2025): Diving into the past: a new assemblage of Neogene elasmobranch microfossils from the eastern Pacific of South America. Papers in Palaeontology, 11(6), 1–25
New species: Dasyatis manuelcamposi, Pochitaserra patriciacanalae
Abstract: The fossil record of chondrichthyans from the Pacific coast of South America is rich and diverse, with the Bahía Inglesa Formation distinguished as one of the most important in the region. Despite the extensive fossil record of cartilaginous fish in the Bahía Inglesa Formation, studies focused on microremains of this group of fish are non-existent. This study describes for the first time a new locality of fossil microremains from the Upper Miocene of northern Chile. Over 300 kg of sediment was extracted at the study locality to examine and identify chondrichthyan fossils smaller than 1 cm. Here, 19 chondrichthyan taxa from the Upper Miocene of Bahía Inglesa are reported: five were identified at the species level, seven at the genus level, three at the family level, and four at the superorder level. Notably, this includes the first record of Sympterygia for the Americas, the first record of Dipturus for the Neogene, and the first mention of Rhinobatos for the Neogene of South America. At the species level, the first description of the basking shark Cetorhinus maximus for South America and the leopard shark Triakis semifasciata in any locality worldwide is provided. Additionally, a new species of ray from the genus Dasyatis and a new genus and species of sawshark from the family Pristiophoridae are proposed. In this research we present the largest number of chondrichthyan microremains collected and described from fossiliferous localities in Chile.

Burrow, C.J. & Turner, S. & Itano, W.M. & Den Blaauwen, J.L. & Stewart, S. (2025): Cynopodius, a long-toothed chondrichthyan from the Carboniferous of Scotland and the USA. Earth and Environmental Science Transactions of The Royal Society of Edinburgh , in press
New species: Cynopodius robustus
Abstract: The distinctive isolated elements of Cynopodius, characterised by their deep narrow base and spatulate crown, were first described (as spine-like elements) by Ramsay Heatley Traquair in the late 19th Century, based on specimens from the Burghlee Ironstone (Serpukhovian, Carboniferous) at Loanhead near Edinburgh, Scotland. The type species Cynopodius crenulatus is also known from older Calciferous Sandstone Measures (Viséan) of Fife. Here we provide evidence that the elements are teeth rather than spines or dermal claspers, as hypothesised elsewhere. Thin sections of the teeth, illustrated for the first time, show osteodentine and tubate dentine forming the crown, covered by a thin outer hypermineralised layer on the cusps, and trabecular osteodentine or acellular bone forming the base. In recent decades, teeth of Cynopodius have also been collected from the lower Carboniferous Sainte Genevieve Formation (Mississippian: Viséan) of Iowa, Kentucky, and West Virginia in the USA. We assign these teeth from Iowa to Cynopodius robustus n. sp. They are distinguished from the type species by their relative robustness, with a ratio of maximum crown length to root length of c. 2:3 for C. traquairi and c. 1:2 for C. crenulatus, and lack of longitudinal curvature. The Scottish and American occurrences, though widely separated in the early Carboniferous, are the only known localities for the genus. The similarity between these over 300-million-year-old teeth and those of Recent long-toothed teleost reef fishes like Ctenochaetus, for instance, suggests that the Cynopodius animals might also have been specialised detritivores.

Egli, H.C. & Goode, B. & Rempert, T. & Rego, C. (2025): Pseudocorax (Chondrichthyes, Lamniformes, Pseudocoracidae) in the Upper Maastrichtian phosphates of Khouribga Province, Morocco. Journal of Paleontology, in press
New species: Pseudocorax heteroserratus
Abstract: A new species of Pseudocorax (Lamniformes, Pseudocoracidae), Pseudocorax heteroserratus n. sp., is described from the upper Maastrichtian phosphates of Morocco. This novel taxon is recognized by a large sample of isolated teeth collected from the upper Couche III layer at the Sidi Chennane quarry in the Oulad Abdoun Basin, Khouribga Province, Morocco. P. heteroserratus is differentiated from other Pseudocorax species by bearing a mesiodistally elongated tooth base, broad crown, and highly variable serrations. The variability in number and extent of serrations along the carinae ranges from completely absent to fully serrated and finely to coarsely serrated, raising speculation on broader Pseudocorax phylogenetics and as to whether the genesis of serrations within Pseudocorax occurred in a singular progressive event or rather from two distinct events. The morphological variability within the new species highlights the importance of large sample sizes in selachian odontological studies using isolated teeth.



Parasites:
Irigoitia, M.M. & Franzese, S. & Alarcos, A.J. & Arredondo, N.J. & Timi, J.T. (2025): An unusual new species at risk, parasite of a critically endangered guitarfish, Pseudobatos horkelii (Elasmobranchi: Rhinobatidae): insights into the phylogeny of Acanthobothrium (Cestoda: Onchoproteocephalidea). Zoologischer Anzeiger, 318, 120–131
New species: Acanthobothrium goleketen
Abstract: Guitarfishes comprise a group of elasmobranchs with a high risk of extinction and whose parasite fauna is largely unknown in the Southwest Atlantic Ocean. The genus Acanthobothrium is one of the most diverse groups of cestodes from elasmobranchs. In the present study, the erection of the new species Acanthobothrium goleketen n. sp., parasitizing Pseudobatos horkelii, is proposed based on both morphological and molecular characters. The new species is assigned to the morphological category 3 and is differentiated morphologically from all congeners in that category and those of the related category 4 by the type of apolysis, total length, number of proglottids, scolex configuration, size of various bothridial structures, length of cephalic peduncle and number of testes. Knowledge about the phylogenetic relationships among Acanthobothrium species is still incipient. This study discusses the interspecific relationships of all formally described and sequenced species of Acanthobothrium on the basis of phylogenetic reconstructions using Bayesian Inference, Maximum Likelihood and Maximum Parsimony. No apparent phylogenetic pattern was observed among species with geographical affinity or species from closely related hosts. In contrast, some species with morphological similarities were grouped in highly supported clades. The new species was catalogued as Critically Endangered in accordance with the status of its host. The great diversity of chondrichthyans in the Argentine Sea and the lack of information about their parasite fauna, highlight the need to increase diversity studies and complete the assignment of conservation categories.

Kita, Y. & Nitta, M. & Abe, H. & Kaburagi, S. & Fujita, T. & Toyota, K. & Kondo, Y. & Kajihara, H. (2025): A new species of Pseudoacanthocephalus (Acanthocephala: Pseudoacanthocephalidae) from Sado Island, Japan, with a report of its accidental occurrence in a marine elasmobranch. Folia Parasitologica, 72, Article 28
New species: Pseudoacanthocephalus sadoensis
Abstract: Three species of amphibian-parasitic acanthocephalans belonging to the genus Pseudoacanthocephalus Petrochenko, 1958 have been recorded in Japan. However, only a limited number of localities have been surveyed, and the distribution of these congeners across other regions of Japan remains unclear. In this study, acanthocephalans of the genus Pseudoacanthocephalus were recovered from both definitive (Rana ornativentris Werner - type host, and Zhangixalus arboreus [Okada et Kawano]) and accidental hosts (Scyliorhinus torazame [Tanaka]) from Sado Island, Japan. Morphological analyses indicate that those specimens represent a new species, Pseudoacanthocephalus sadoensis sp. n., which may be endemic to the island. Additionally, our report of the incidental occurrence of this species in a marine elasmobranch represents the first documented case of a Pseudoacanthocephalus species found in a marine host.

Hanselman, K.M. & Gobiraj, R. & Jensen, K. (2025): Revision of the Lecanicephalidean Genus Flapocephalus Deshmukh, 1979 (Eucestoda) from Cowtail Rays (Genus Pastinachus Rüppell) (Myliobatiformes: Dasyatidae Jordan and Gilbert) with the Description of Four New Species. Journal of Parasitology, 111(5), 582–605
New species: Flapocephalus monostylorchis, Flapocephalus capitonis, Flapocephalus rudkinorum, Flapocephalus infundibulapex
Abstract: The genus Flapocephalus Deshmukh, 1979, is a little-known group of lecanicephalidean cestodes parasitizing cowtail rays (genus Pastinachus Rüppell) mainly in the Indo-Pacific region. Since the erection of the genus, with Flapocephalus trygonis Deshmukh, 1979, as the type species, and the description of a second species, Flapocephalus saurashtri Shinde and Deshmukh, 1979, both from Pastinachus sephen (Fabricius) from India, reports of this genus have been restricted mainly to brief mentions or discussion of its validity and taxonomic placement. More recently, phylogenetic analyses based on molecular sequence data that included specimens of Flapocephalus have supported Flapocephalus as a distinct genus allied with the Polypocephalidae Meggitt, 1924. Limited by the amount of detail provided in the original descriptions, the unavailability of type material, and the lack of a detailed generic diagnosis, we aimed to fully characterize the genus based on newly collected specimens. A total of 38 specimens of Pastinachus, representing 3 of the 5 described species and 1 undescribed species, from throughout the Indo-Pacific region were examined for specimens of Flapocephalus. Worms were prepared for examination with light and scanning electron microscopy and as histological sections. A subset of specimens was included in a phylogenetic analysis based on data for a portion of the 28S rDNA gene. Overall, these specimens were found to include the type species, 4 new species that are described herein (Flapocephalus monostylorchis Hanselman and Jensen n. sp., Flapocephalus capitonis Hanselman and Jensen n. sp., Flapocephalus rudkinorum Hanselman and Jensen n. sp., and Flapocephalus infundibulapex Hanselman and Jensen n. sp.), and 4 putative new species. Flapocephalus trygonis is redescribed from specimens from Pastinachus ater (Macleay) from Sri Lanka, and a neotype is designated. The newly described species are distinct genetically and can be distinguished morphologically from the existing species and one another based on a combination of total length, the shape of the apical organ, and the arrangement of testes and vitelline follicles. A revised diagnosis of the genus and a key to the described species are presented, as is a hypothesis of the interrelationships resulting from a maximum likelihood analysis including 4 of the 5 described species and the 4 putative new species. The presence of 4 glandular, sac-like structures surrounded by scolex proper, with channels that open to the outside at the base of the apical organ, is reported in lecanicephalidean tapeworms for the first time.

New species: Kroyeria cresseyi
Abstract: This study focuses on the taxonomy and systematics of Kroyeria, a genus of ectoparasitic copepods found on the gills of sharks. Members of the genus Kroyeria exhibit species-specific appendage ornamentation, including denticles, membranes, and setules, in addition to the setae and spines typical of most copepods. The taxonomy and systematics of Kroyeria have been hampered by the lack of observation of these fine morphological details. This study is a systematic revision of the genus in which 11 species of Kroyeria are redescribed, 6 species are synonymized, and 5 new species are described: Kroyeria branchiocetes n. sp. from Carcharhinus amblyrhynchos from the Red Sea, Kroyeria cresseyi n. sp. from Triakis semifasciata from off California, Kroyeria decepta n. sp. from Carcharhinus obscurus from the Pacific Ocean off Mexico, Kroyeria procerobscena n. sp. from Carcharhinus leucas from off Madagascar, and Kroyeria rhophemophaga n. sp. from Galeorhinus galeus from off California. With this work, Kroyeria now comprises 20 valid species. The 16 species of Kroyeria that were examined in this study were scored for 44 morphological characters, which were used for a phylogenetic analysis of the genus.

New species: Sphyrnacestus ananas, Sphyrnacestus eusphyrensis, Sphyrnacestus latocapitus, Sphyrnacestus paralewinensis, Phoreiobothrium angustivastum, Phoreiobothrium danae, Phoreiobothrium magnaloculum, Phoreiobothrium posteroporum, Phoreiobothrium tesserascolex, Phoreiobothrium waeschenbachae
Abstract: The onchoproteocephalidean cestodes reported on herein were obtained from requiem (Carcharhinidae) and hammerhead (Sphyrnidae) sharks during fieldwork conducted over the past several decades off Australia, Japan, Malaysian and Indonesian Borneo, Mexico, Mozambique, Senegal, Taiwan, the United States, and Vietnam. Sequence data were generated for the D1–D3 region of the 28S rDNA gene for 36 specimens of 23 species of onchoproteocephalideans. The phylogenetic tree resulting from a Maximum Likelihood analysis revealed 3 subclades consistent with major morphological and host differences among included taxa. One subclade consisted of species of Triloculatum, which have bothridia with 3 subloculi, basal prongs on their hooks that are at least half as long as the axial and abaxial prongs, and a uterus that extends essentially the length of the proglottid. These species parasitize requiem sharks. Another subclade consisted of a subset of species currently assigned to Phoreiobothrium, all of which came from hammerhead sharks. These species have bothridia with 5–11 subloculi, basal prongs on their hooks that are less than half as long as the axial and abaxial prongs or are entirely absent, and a uterus that extends only to the level of the terminal genitalia. The final subclade consisted of species of Phoreiobothrium that have bothridia with 8 or more subloculi, basal prongs on their hooks that are more than half as long as the axial and abaxial prongs, and a uterus that extends much of the length of the proglottid, all of which parasitize requiem sharks. Sphyrnacestus n. gen. is erected for species in the second subclade, and the diagnoses of Phoreiobothrium and Triloculatum are emended. Four new species of Sphyrnacestus n. gen. are described, and the 5 species from hammerhead sharks currently assigned to Phoreiobothrium that are consistent with the morphology of members of the second subclade are transferred to the new genus. Six new species of Phoreiobothrium are also described. Evidence of 16 undescribed species of Phoreiobothrium and 1 undescribed species of Triloculatum is presented. The family Phoreiobothriidae is resurrected for the 3 genera, which all possess bothridia with tri- or bi-pronged hooks and subloculi. Members of this family are predicted to be found in other species of Carcharhinidae and Sphyrnidae. Furthermore, we predict they will not be found to parasitize members of other families of carcharhiniform sharks because phoreiobothriids appear to be restricted to sharks that possess the scroll type rather than the conicospiral type of spiral intestine.

(2025): Evidence from integrative taxonomy reveals non-monophyly in Pseudocharopinus (Copepoda: Lernaeopodidae), with description of a new species from the Southwestern Atlantic. Systematic Parasitology, 102(6), Article 56
New species: Pseudocharopinus tenshken
Abstract: A new species, Pseudocharopinus tenshken n. sp., is described and illustrated as a parasite of juvenile Squalus acanthias from Argentine waters in the South Atlantic. Although morphologically similar to Pseudocharopinus bicaudatus, a species widely distributed on the same host, distinct morphological differences are evident. The new species differs from P. bicaudatus in its dorsal shield, which is more elongated and has more developed sclerites. Additionally, the cephalothorax of the new species reaches 82% of the trunk length, whereas it is shorter in P. bicaudatus. In contrast, the maxilla in P. bicaudatus extends up to 65% of the trunk length, while in P. tenshken n. sp., it reaches 76% of the trunk length. These morphological distinctions are supported by a genetic divergence of 17% from P. bicaudatus. In the COI phylogenetic tree, a strongly supported clade is observed, consisting of (Pseudocharopinus malleus (P. bicaudatus + Lernaeopoda bivia)). Then, Salmincola spp. appears in a clade with low support, followed by Pseudocharopinus pillai. Later, another strongly supported clade includes (Pseudocharopinus tenshken n. sp. (Brianella corniger + Pseudocharopinus pteromylaei)). Based on our results, the genus Pseudocharopinus should be considered non-monophyletic. These findings suggest that at least two independent Lernaeopodid infection events occurred in chondrichthyans.

Fossils reveal a massive shark that ruled Australia in dinosaur times

Date: November 22, 2025

Source: Swedish Museum of Natural History

Summary: Around 115 million years ago, northern Australia’s seas hosted a colossal shark that rewrites what we thought we knew about early ocean predators. New fossil discoveries show that modern-type sharks were experimenting with gigantic sizes far earlier than scientists believed, competing with the marine “monsters” of the dinosaur age.

DNA in seawater reveals lost hammerhead sharks

Date: November 8, 2025

Source: Florida International University

Summary: A revolutionary eDNA test detects endangered hammerhead sharks using genetic traces left in seawater, eliminating the need to capture or even see them. This powerful tool could finally uncover where these elusive species still survive, and help protect them before they disappear for good.

Killer whales perfect a ruthless trick to hunt great white sharks

Orcas in Mexico are flipping young great whites for their livers — a chilling display of intelligence and adaptation.

Date: November 3, 2025

Source: Frontiers

Summary: In the Gulf of California, a pod of orcas known as Moctezuma’s pod has developed a chillingly precise technique for hunting young great white sharks — flipping them upside down to paralyze and extract their nutrient-rich livers. The behavior, filmed and documented by marine biologists, reveals a level of intelligence and social learning that suggests cultural transmission of hunting tactics among orcas.

Glowing shark and hidden crab found deep off Australia

Date: October 9, 2025

Source: CSIRO

Summary: In a stunning glimpse into the mysteries of the deep, scientists have uncovered two new marine species off Western Australia—a glowing lanternshark and a tiny porcelain crab. The discoveries, made from specimens collected during a 2022 CSIRO research voyage, highlight both the dazzling adaptations of life in the deep sea and the vast number of species yet to be described.

From gentle giants to ghostly hunters, sharks face an unseen peril

Date: October 5, 2025

Source: University of Hawaii at Manoa

Summary: New research reveals that deep-sea mining could dramatically threaten 30 species of sharks, rays, and ghost sharks whose habitats overlap with proposed mining zones. Many of these species, already at risk of extinction, could face increased dangers from seafloor disruptions and sediment plumes caused by mining activity.

Breakthrough wetsuits slash shark attack injuries and save lives

Date: September 25, 2025

Source: Flinders University

Summary: Shark experts tested four innovative wetsuit materials to measure how well they reduce shark-bite injuries. The results show they can lessen major trauma, blood loss, and even save lives when compared to standard neoprene. While not a perfect shield, these suits represent a leap forward in personal protection.

Ghost sharks grow teeth on their heads to mate

Date: September 5, 2025

Source: University of Florida

Summary: Ghost sharks have evolved rows of true teeth on a bizarre forehead rod used for mating. Fossil and genetic evidence revealed the tenaculum’s teeth develop the same way as those inside the mouth, offering a striking example of evolution’s ability to repurpose biological tools.
