ADJUSTMENT OF CITATION STYLE IN SHARK REFERENCES
We started to change our old (and unique!) citation style to adapt to the APA citation style (for information please see: https://www.mendeley.com/guides/apa-citation-guide) to make the usage of references listed in shark references easier and more compatible with a widely accepted reference style adopted by several international scientific journals. The transition is ongoing, so far 21445 (last month: 20893) references are changed.
NEW VERSION 10_2021! New database report published by team shark-references! NEW VERSION 10_2021!
- You want to know how many species of sharks, rays and chimaeras there are? - You want to know the distribution of species among the orders or families? - You want to know the references of the first descriptions? - You want a list of all sharks, rays and chimaeras ever described with their synonyms?
Our new data report can answer all these questions for you!
Abstract: The table and provided download links below are intended for informational use in Chondrichthyan research. The allocation aims for faciliating to find species numbers and most recent information on taxonomic changes. We will regularly update the table and download links at lest twice annually. The updates will be announced on facebook (https://www.facebook.com/sharkreferences) and in our monthly newsletter (sign up here: https://eepurl.com/sJNGb). The Excel sheet allows for the application of individual filter- and sorting options. The list of described spsecies complements taxonomic information for the list of valid species by providing synonyms and / or new taxonomic combinations.

Jabado, R.W. & Ebert, D.A. & Al Dhaheri, S.S. (2022): Resolution of the Aetomylaeus nichofii species complex, with the description of a new eagle ray species from the northwest Indian Ocean and a key to the genus Aetomylaeus (Myliobatiformes: Myliobatidae). Marine Biodiversity,52, Article 15 New species: Aetomylaeus wafickii Abstract: In recent years, the eagle ray family Myliobatidae has undergone major taxonomic revisions due to molecular and morphological findings. A new species of eagle ray, Aetomylaeus wafickii sp. nov., is described based on specimens collected from the Arabian Gulf, Northwest Indian Ocean. The new species externally most closely resembles A. caeruleofasciatus White, Last, & Baje, 2015 in White et al. 2016 and A. nichofii (Bloch & Schneider, 1801). It can be distinguished from these species by a combination of morphological and meristic characteristics including a higher number of transverse pale bluish to light grey bands on its dorsal surface (8–10 in Aetomylaeus wafickii sp. nov. vs 5–8 in A. caeruleofasciatus and A. nichofii), a higher number of tooth plate rows (13–15 vs 7), a shorter upper tooth plate width (3.1–4.3 vs 4.6–7.5%DW), and a shorter tail ((0.9–1.6) vs (1.4–1.8)) times disc width. Pelvic fin radial counts separate the new species from A. nichofii for males (14–16 vs 16–19) and females (16–19 vs 20–21). Geographically, it occurs from the southern Red Sea, eastwards to the Arabian Sea, and south to Sri Lanka, including in the Arabian Gulf. It appears to be frequently caught as bycatch in gillnets due to its habit of schooling, and is considered particularly susceptible to impacts from regional fisheries. Morphological and meristic findings complement prior molecular evidence documenting three species within the A. nichofii complex. A key to the genus Aetomylaeus is provided for the first time.
Extinct Chondrichthyes: Adnet, S. & Charpentier, V. (2022): A new elasmobranch fauna from the early Miocene of Sharbithat (Sultanate of Oman) reveals the teeth of an ancient fantail stingray. Geologica Acta, 20.2, 1-13 New species: Taeniurops tosii Abstract: Here we describe a new elasmobranch assemblage consisting of isolated dental material from the Aquitanian near-shore marine deposits of the Shuwayr and Warak formations at Sharbithat, in eastern Sultanate of Oman. The faunal composition clearly indicates affinities to other early Miocene elasmobranch-bearing localities worldwide. This assemblage is predominantly composed of large and common pelagic sharks as well as teeth attributable to a new species of fantail stingray, Taeniurops tosii, as old as the oldest undisputable fossil records of Taeniurops. The study of this fossil assemblage presented here improves the knowledge of the ancient elasmobranchs that frequented the eastern Arabian coasts during the closure of the Neotethys and the birth of the Arabian Sea.
Ivanov, A.O. (2022): New late Carboniferous chondrichthyans from the European Russia. Bulletin of Geosciences, 97(2), in press New genus: Heslerodoides, Gzhelodus, Samarodus New species: Heslerodoides triangularis, Gzhelodus serratus, Samarodus flexus Abstract: Three new genera Heslerodoides gen. nov., Gzhelodus gen. nov., and Samarodus gen. nov. were erected on the basis of numerous isolated teeth found in the late Carboniferous of European part of Russia. The teeth of the ctenacanthiform Heslerodoides resemble the teeth of Heslerodus and demonstrate the morphological variations of teeth in their dentition. The protacrodontid euselachian Gzhelodus is closely related to Deihim and Tiaraju. The peculiar teeth of Samarodus possess a combination of features previously unknown in the Palaeozoic chondrichthyans. The new taxa contribute to the knowledge of the variety of dentitions in the Carboniferous shark.
Parasites: Caira, J.N. & Bueno, V. & Jensen, K. (2021): Emerging global novelty in phyllobothriidean tapeworms (Cestoda: Phyllobothriidea) from sharks and skates (Elasmobranchii). Zoological Journal of the Linnean Society, 193(4), 1336–1363 New genus: Ruhnkebothrium, Yamaguticestus, Rockacestus New species: Ruhnkebothrium mattisi, Ruhnkebothrium bajaense, Yamaguticestus metini, Rockacestus carvajali, Rockacestus conchai Abstract: New genera are erected for three clades of tapeworms originally discovered using molecular sequence data. The morphological features of each are characterized after examination of specimens with light and scanning electron microscopy. Rockacestus gen. nov. parasitizes skates. Ruhnkebothrium gen. nov. parasitizes hammerhead sharks. Yamaguticestus gen. nov. parasitizes small squaliform sharks and catsharks. The novelty of these genera is supported by a taxonomically comprehensive molecular phylogenetic analysis of the D1–D3 region of the 28S rDNA gene, which, with the addition of newly generated sequence data, is the first to include representation of 15 of the 18 genera of phyllobothriideans plus the three new genera. Five new species are described from elasmobranchs in the western Atlantic Ocean, the Gulf of California, Chile, the Falkland Islands and South Africa to help circumscribe the new genera. Two of the genera provide appropriate generic homes for ten species of phyllobothriideans from catsharks and skates with uncertain generic affinities and thus resolve longstanding taxonomic issues. Given that these genera parasitize some of the most poorly sampled groups of elasmobranchs (i.e. hammerhead sharks, squaliform sharks, catsharks and skates), based on the strict degree of host specificity observed, we predict that further work on other members of these groups will yield as many as 200 additional species in these three genera of tapeworms globally. This brings the total number of genera in the Phyllobothriidea to 21.

Sharp decline in basking shark sightings in California

Summary: A recent study confirms a striking decrease in basking shark sightings in the California Current Ecosystem after the 1970s and 1980s and examines what is driving their presence and distribution.
Addressing knowledge gaps in shark and ray research
Date: March 10, 2022
Source: Virginia Tech
Summary: Sharks and rays are one of the most ancient vertebrate groups, as well as one of the most endangered. Researchers still know very little about many shark and ray species and the environments in which they live, particularly rare species and those that dwell in remote areas, where resources and capacity for conducting study and monitoring are scarce.
Do sharks get their ZZZs? New evidence shows it’s not all about the hunt
Date: March 15, 2022
Source: Simon Fraser University
Summary: The first physiological evidence that sharks take a break from tracking prey to catch a few winks has been uncovered by a researcher who specializes in sleep among aquatic creatures, from sharks to crocodiles. The comparative sleep physiologist studied the metabolic signatures of sleep and behavioral sleep indicators among New Zealand's draughtsboard sharks. His research found that they produced a lower metabolic rate and recumbent body posture when inactive for longer than five minutes, supporting the idea that they were conserving energy by sleeping.
