Affiliation: Sharks Educational Institute  

Sharks Educational Institute is a non-governmental organization dedicated to the education for the marine conservation, founded by Fernando Reis in 2016.
Our focus is the issues's development related to the marine environmental education of the youngers and their active participation in the conservation of the sharks' species in their natural habitats.
Our vision is to enhance the public knowledge of the marine balance, based on sharks' conservation with our stakeholders' influence and involvement.
Our mission is to create new educational events for the knowledge of marine biodiversity supported on sharks.

Extinct Chondrichthyes:
ENGELBRECHT, A. & MÖRS, T. & REGUERO, M.A. & KRIWET, J. (2016): A new sawshark, Pristiophorus laevis, from the Eocene of Antarctica with comments on Pristiophorus lanceolatus. Historical Biology, in press
New species: Pristiophorus laevis
Abstract: The highly fossiliferous Eocene deposits of the Antarctic Peninsula are among the most productive sites for fossil remains in the Southern Hemisphere and offer rare insights into high-latitude faunas during the Palaeogene. Chondrichthyans, which are represented by abundant isolated remains, seemingly dominate the marine assemblages. Eocene Antarctic sawsharks have only been known from few isolated rostral spines up to now, that were assigned to Pristiophorus lanceolatus. Here, we present the first oral teeth of a sawshark from the Eocene of Seymour Island and a re-evaluation of previously described Pristiophorus remains from Gondwana consisting exclusively of rostral spines. The holotype of Pristiophorus lanceolatus represents a single, abraded and insufficiently illustrated spine from the Oligocene of New Zealand. All other Cenozoic rostral spines assigned to this species are morphologically very indistinct and closely resemble those of living taxa. Consequently, we regard this species as dubious and introduce a new species, Pristiophorus laevis, based on oral teeth. The combination of dental characteristics of the new species makes it unique compared to all other described species based on oral teeth. Rostral spines from the Eocene of Seymour Island are assigned to this new species whereas those from other Cenozoic Gondwana localities remain ambiguous.

IVANOV, A.O. (2016): Chondrichthyans from the Lower Permian of Mechetlino, South Urals, Russia. Bulletin of Geosciences, 91 (4): 717–729
New genus: Kungurodus
New species: Kungurodus obliquus
Abstract: A chondrichthyan assemblage is described from the Early Permian (Artinskian and Kungurian) of Mechetlino Quarry (Bashkortostan, South Urals). The assemblage includes the teeth of a symmoriiform, a sphenacanthid euselachian and an anachronistid neoselachian, as well as various denticles and scales. The dentition of Cobelodus aculeatus has been restudied. The teeth of a new genus of symmoriiform shark are described as Kungurodus, the internal structure of which is reconstructed using microtomography.

FIGUEROA, R.T. & GALLO, V. (2017): New chondrichthyan fin spines from the Pedra de Fogo Formation, Brazil. Journal of South American Earth Sciences, in press
New genus: Rubencanthus
New species: Rubencanthus diplotuberculatus, Sphenacanthus ignis, Bythiacanthus lopesi,
Abstract: The Pedra de Fogo Formation is located at the northeast region of Brazil and possesses a diverse palaeobiota mainly composed by plants and vertebrate remains of Lower Permian age (Cisuralian). The palaeoichthyofauna includes several chondrichthyans (e.g. Sphenacanthus maranhensis, Taquaralodus albuquerquei, Itapyrodus punctatus and Anisopleurodontis pricei) but also include osteichthyans as the ‘palaeoniscoid’ Brazilichthys macrognathus and several actinopterygian and sarcopterygian remains. This variety of fish taxa of both marine and freshwater affinities is important for understanding taxonomical diversity and distribution of vertebrates from Western Gondwana. Here, specimens collected at the Pastos Bons locality, near Nova Iorque at Maranhão State, are described as two new species for known genera, Sphenacanthus ignis sp. nov. and Bythiacanthus lopesi sp. nov., also a new genus and a new species Rubencanthus diplotuberculatus gen. et sp. nov. that exhibit a distinct pattern of ornamentation from all previously known Palaeozoic chondrichthyans. These new records highlight the importance of more palaeontological studies for the Pedra de Fogo Formation and enlarge the variety of chondrichthyan for the locality.

VIANA, S.T. & LISHER, M.W. & DE CARVALHO, M.R. (2017): Two new species of short-snouted dogfish sharks of the genus Squalus Linnaeus, 1758, from southern Africa (Chondrichthyes: Squaliformes: Squalidae). Marine Biodiversity, in press
New species: Squalus margaretsmithae, Squalus mahia
Abstract: Species composition of the genus Squalus from the eastern Atlantic and western Indian oceans is still poorly known, with three to four species often recognized: S. acanthias, S. megalops, S. blainvillei, and S. mitsukurii. A fifth species, S. acutipinnis, was recently redescribed as valid in the region, although morphological variation was noted among its type specimens that indicated the presence of two different forms. The second form is described herein as Squalus margaretsmithae sp. nov. and distinguished from S. acutipinnis based on external morphological characters. Squalus mahia sp. nov. is also described from southern Africa based mostly on material collected from Madagascar. Squalus mahia sp. nov. stands out from other Squalus species by having a conspicuously slender body, elongate and thin dorsal fin spines, narrow caudal fin, and other external proportions. These two species are often misidentified with the Australian S. megalops because they share a short snout, white postventral caudal margins, lanceolate and unicuspid dermal denticles, and a low number of vertebrae. Comparative analyses are provided here between Squalus margaretsmithae sp. nov., Squalus mahia sp. nov., and morphologically similar species that also share these features, including S. brevirostris, S. crassispinus, S. acutipinnis, S. altipinnis, and S. hemipinnis. A taxonomic evaluation of the nominal species S. megalops and its occurrence in the region is also discussed.

WHITE, W.T. & LAST, P.R. & MANA, R.R. (2017): A new species of velvet skate, Notoraja sereti n.sp. (Rajiformes: Arhynchobatidae) from Papua New Guinea. Zootaxa, 4244 (2):  219–230
New species: Notoraja sereti
Abstract: A new arhynchobatin skate, Notoraja sereti n. sp., is described based on three specimens collected from off Madang (Papua New Guinea) at depths of 800–980 m. This medium-size Notoraja skate shares with other velcro skates from the Western Pacific, N. alisae, N. fijiensis, N. inusitata and N. longiventralis, a ventral surface covering of fine denticles giving the skin a velvety feel. Notoraja sereti differs from all of these species in having a shorter snout (preorbital length 10.1–11.1 vs. 11.5–14.5% TL, prenasal length 8.2–8.9 vs, 9.8–12.1% TL), shorter head (dorsal head length 15.2–16.2 vs. 17.1–19.3% TL, ventral head length 21.6–22.9 vs. 22.9–25.9% TL), fewer pectoral-fin radials (total radials 58–60 vs. 61–74), and fewer vertebrae (predorsal diplospondylous centra 66–71 vs. 72–82, predorsal centra 90–95 vs. 98–107, total centra 126–131 vs. 135–152).

WHITE, W.T. & EBERT, D.A. & MANA, R.R. & CORRIGAN, S. (2017): Etmopterus samadiae n. sp., a new lanternshark (Squaliformes: Etmopteridae) from Papua New Guinea. Zootaxa, 4244 (3): 339–354
New species: Etmopterus samadiae
Abstract: A new species of lanternshark, Etmopterus samadiae (Squaliformes: Etmopteridae), is described from off northern Papua New Guinea, in the western Central Pacific Ocean. The new species resembles other members of the “Etmopterus lucifer” clade in having linear rows of dermal denticles and most closely resembles E. brachyurus from the western North Pacific. The new species occurs along insular slopes between 340 and 785 m depth. The new species can be distinguished from other members of the E. lucifer clade by a combination of characteristics, including length of anterior flank branch markings being slightly shorter than its posterior branch, a longer caudal base marking, and irregular and variable number of black, horizontal, dash-like marks on sides of body. Molecular analysis based on the NADH2 marker further supports the distinction of E. samadiae from other members of the E. lucifer clade.
