New described species/Taxonomic News:


KEMPER, J.M. & EBERT, D.A. & NAYLOR, G.J.P. & DIDIER, D.A. (2014): Chimaera carophila (Chondrichthyes: Chimaeriformes: Chimaeridae), a new species of chimaera from New Zealand. Bulletin of Marine Science, 91 (1): 63-81

A new species of chimaeroid, Chimaera carophila sp. nov., is described from 37 specimens collected from deepwater slopes and seamounts around New Zealand. The new species is distinguished from its closest congeners, Chimaera fulva Didier et al. 2008, Chimaera macrospina Didier et al. 2008, and Chimaera obscura Didier et al. 2008, by its uniform pale-brown coloration, geographic distribution, and a combination of morphological characters, including longer dorsal and ventral caudal fin bases, a shorter first dorsal fin height, a shorter dorsal fin spine, and shorter claspers that are divided distally for one-third of their length. Chimaera carophila sp. nov. also can be distinguished from closely related species in New Zealand and Australian waters based on DNA sequence divergence of the NADH2 gene. Comparisons of body size in a large sample of specimens show considerable overlap in character ranges among congeners making species distinctions difficult. New combinations of morphometrics are suggested including ratios of head length to eye length and dorsal spine length to head length, to better distinguish among species of chimaeroids that are similar in overall appearance and size. Also, a key to New Zealand and Australian Chimaera species is provided.


LUND, R. & GROGAN, E.D. & FATH, M. (2014):  On the relationships of the Petalodontiformes (Chondrichthyes). Paleontological Journal, 48 (9): 1015-1029
New genus: Fissodopsis
New species: Fissodopsis robustus
Abstract: The Petalodontiformes are Upper Paleozoic marine euchondrocephalan chondrichthyans known primarily from isolated teeth. Few dentitions have been reported, among them that of the Permian Janassa bituminosa and “Janassa” korni and the Serpukhovian, Mississippian Belantsea montana, Obruchevodus griffithiNetsepoye hawesiand Siksika ottae. A dentition has been reconstructed for the PennsylvanianPetalodus ohioensis. New information on dentitions and postcranial morphology is now introduced for petalodont remains from the Bear Gulch Limestone of Montana (USA). These include N. hawesi, Petalorhynchus beargulchensis, several specimens bearing teeth of theFissodus form, and a new genus and species, Fissodopsis robustus. Analysis of all material reveals dignathic heterodonty as prevalent among the Upper Mississippian petalodonts, with distinct regionalization resulting in large anterior and small lateral teeth. Fissodus-style teeth are found as the lower median tooth position of most heterodont dentitions, with aCtenoptychius-like upper anterior tooth or teeth, accompanied by lateral upper and lower teeth of Janassa-like form. As heterodonty seems to have been the plesiomorphic condition not only in these petalodonts but for the Euchondrocephali as well, a model is proposed to explain the derived homodont conditions found in Petalodus (Hansen, 1985),Polyrhizodus (Lund, 1983), Belantsea (Lund, 1989), and J. bituminosa (Jaekel, 1899). The principally dentition-based cladistic analysis retains the previously erected families Petalodontidae, Belantseidae, and Janassidae, rejects the assignment of ”J.” korni to Janassa, and suggests a heterodont clade for the remaining taxa. Two new families are designated on the basis of these data, the Petalorhynchidae and the Obruchevodidae.

LYAPIN, V.R. & BAGIROV, S.V. (2014):  The first record of Copodus Davis, 1883 (Chondrichthyes, Copodontiformes) from the Steshevian Regional Stage (Serpukhovian, Lower Carboniferous) of the Moscow Region. Paleontological Journal, 48 (10): 1045-1059
New species: Copodus lebedevi
Abstract: Deposits of the Steshevian Regional Stage of the Lower Carboniferous Serpukhovian of the Moscow Region have yielded abundant and taxonomically diverse fish remains, which are usually disarticulated but frequently well preserved. The dental plates of chondrichthians assigned to the genus Copodus Davis, 1883 (Copodontiformes, Copodontidae), collected in the Zabor’e and Kalinovskie Vyselki localities (Moscow Region, Serpukhovskii District), have not previously been recorded in these beds. A new species,Copodus lebedevi sp. nov., is established based on the shape of plates, crown sculpturing, and unique shape of the wear facet. C. angulatus (Davis, 1883); C. cornutus Davis, 1883; C. planus (Davis, 1883); C. spatulatus Davis, 1883, C. aff. planus (Davis, 1883), C. cf.prototypus Davis, 1883, and C. aff. spatulatus Davis, 1883 are described for the first time from the Serpukhovian of Russia. The occlusal pattern of the upper and lower jaw plates in various species of the genus Copodus is reconstructed experimentally based on the shape of the wear facet. This shape depends on the structure of the upper and lower jaw plates and their particular parts and is distinctive in each species.

IVANOV, A.O. & LEBEDEV, O.A. (2014):  Permian chondrichthyans of the Kanin Peninsula, Russia. Paleontological Journal, 48 (9): 1030-1043
New genus: Kanodus
New species: Kanodus robustus
Abstract: Chondrichthyan fish remains reported from the Permian (Kazanian) deposits of the Chiosha Bay, and the lower course of the Nadtey River of the Kanin Peninsula (Nenets Autonomous District, Arkhangelsk Region, Russia) include dental elements and scales belonging to Stethacanthus cf. S. altonensis (St. John et Worthen, 1875), Symmoriiformes gen. indet., “Ctenacanthus” sp. and “Lissodus” sp., Euselachii gen. indet.,Adamantina benedictae Bendix-Almgreen, 1993 and Kanodus robustus sp. nov. The latter genus is assigned to the previously monotypic family Psephodontidae. The record ofStethacanthus in the Middle Permian of Russia is its youngest occurrence worldwide, whilst the occurrence of Adamantina benedictae in the Middle Permian of the Kanin Peninsula is older than the Greenland record.

GROGAN, E.D. & LUND, R. & FATH, M. (2014):  A New Petalodont Chondrichthyan from the Bear Gulch Limestone of Montana, USA, with Reassessment of Netsepoye hawesi and Comments on the Morphology of Holomorphic Petalodonts. Paleontological Journal, 48 (9): 1003-1014
New genus: Obruchevodus
New species:  Obruchevodus griffithi
Abstract:  A new holomorphic petalodont from the Bear Gulch Limestone,Obruchevodus griffithi, is described and features of the related Netsepoye hawesi are reinterpreted. Comparison of these taxa with the holomorphic petalodontsJanassa bituminosa, Belantsea montana, and Siksika ottae provide insight into petalodont anatomical form and variation. All holomorphic material supports holostyly and nested, subcranial branchial arches. Teeth occur in families with linguo-labial replacement but alignment of most families relative to the jaw ramus results in a staggered tooth alignment between adjacent tooth families. Symphysial teeth are the exception to this pattern. Tooth retention is clearly indicated only in the homodont Janassa bituminosa. In contrast there is no evidence of tooth retention in examined petalodonts with a heterodont dentition. There is variation in styles of squamation among all forms; sexual dimorphism in scale development and distribution are suggested as well. Despite depressiform and compressiform conditions there is commonality in possession of a lobular, anteriorly extended and high aspect ratio pectoral fin, large pelvic fins, and absence of fin spines. Pectoral fins provide the primary means of locomotion. Variation in the ventral aspect of the pelvic girdle anatomy exists between that interpreted for Janassa and that documented by Obruchevodus andNetsepoye. Male claspers are long and highly flexible. Laterally compressed body forms display two dorsal fins (first being largest) that are variable in their vertical expanse along the length of the fin. Cranial anatomy shows some correspondence to general features of the Holocephali. Meckel’s cartilage is dorso-ventrally deep, as in extant chimaeroids, with contralaterals in symphysial fusion. Mandibular labial cartilages, when present, may be sexually dimorphic.

HAMM, S.A. 2015 Paraptychodus washitaensis n. gen. et n. sp., of Ptychodontid shark from the Albian of Texas, USA. Cretaceous Research, 54: 60-67
SpeciesParaptychodus washitaensis
Abstract: A new genus and species of Ptychodontiform elasmobranch, Paraptychodus washitaensis n. gen. et n. sp. is described on the basis of 13 teeth from the Middle Albian Duck Creek Formation of the Washita Group in north central Texas, USA. This material is significant as it demonstrates an intermediate tooth form between the Lonchidiidae andPtychodus with regard to occlusal ornamentation of the crown and tooth root morphology; the new taxon represents the earliest member of the family Ptychodontidae in North America. Analysis of dental characters and stratigraphic occurrences within the family suggests that P. washitaensis is a basal taxon and is the most recent ancestor ofPtychodus. Morphological trends of derived species of Ptychodus demonstrate continuous specialization in tooth crown morphologies. The diagnosis of P. washitaensis from the upper Albian of Texas adjusts the stratigraphic distribution of the genus Ptychodus to lower Cenomanian through lower Campanian.

Rare Shark That Inspired Sea Monster Myths Is Caught
Frilled sharks are rarely seen denizens of the deep that resemble their dinosaur-era ancestors.

With its gaping, tooth-filled mouth and its slender, eel-like body, it’s not hard to see why scientists think the frilled shark may have inspired ancient tales of sea monsters. Looking like something out of a nightmare, the deep-sea creature is rarely seen. But fishers in Australia pulled one up this week.

The frilled shark is often called a “living fossil” because it is thought to have changed little in about 80 million years. The fish also bears a resemblance to ancestor species that lived during the time of the dinosaurs.

On Tuesday, Australian media reported that a fishing trawler pulled up a six-foot-long (two-meter) frilled shark in waters near Lakes Entrance off southeastern Victoria, Australia.

Simon Boag of Australia’s South East Trawl Fishing Association told the Australian Broadcasting Corporation that no local fisher had ever seen the creature before. “It does look 80 million years old,” Boag told the ABC. “It looks prehistoric. It looks like it’s from another time!” (See rare video of another species of “sea serpent.”)

“It has 300 teeth over 25 rows, so once you’re in that mouth, you’re not coming out,” he said. 

The shark "was on its last legs" when it made it to the surface, Boag told National Geographic.

Boag said the frilled shark was caught in about 3,300 feet (1,000 meters) of water. The species has previously been found at depths up to 5,000 feet (1,500 meters) but is generally thought to live no deeper than 4,000 feet (1,200 meters).  than 4,000 feet (1,200 meters).

Australia’s national science agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), confirmed that the specimen was a frilled shark.

Frilled sharks are occasionally seen at the surface, mostly when they are sick. Most known specimens have been around six feet (two meters) in length. But the California-based MarineBio Conservation Society says that the netting of a 25-foot-long (7.6-meter) shark related to the frilled shark in 1880 “suggests there may be some giant frilled sharks in the sea that could be taken for sea serpents.”

In 2007 a 5.3-foot-long (1.6-meter) frilled shark was found in shallow water in Japan and transferred to a marine park. It died hours after being caught.The shark "was on its last legs" when it made it to the surface, Boag told National Geographic.

The Protect Africa's Sawfishes project would be very grateful for any further donations of unused, point-and-shoot digital cameras to the project.

The Protect Africa's Sawfishes project aims to assess where in Africa sawfishes can still be found, in order to focus future conservation and research efforts in those areas. In 2014, interviews with fishers, fish traders and fisheries observers were carried out along the entire Mozambican coast, with the help of the Mozambican Fisheries Research Institute (Instituto Nacional de Investigação Pesceira, IIP). As part of this work, training was provided to IIP staff members in identifying sawfish species and collecting basic information from any sawfishes they might see during their work at fish landings sites or as observers on industrial fishing vessels. Two digital cameras were donated to the project, and these were provided to IIP staff who were encouraged to take photos of sawfishes and other unusual shark and ray species. 
In December 2014, Martinho Padera, who works for IIP's office in Beira, was working as an observer on a shrimp trawler fishing in southern Mozambican waters. They caught three saw sharks as bycatch during their trawls, and Martinho was able to take photographs and length measurements of these rare, deep-water sharks. This shows how valuable a digital camera can be in encouraging local staff to collect additional data and to take an interest in species which are usually simply discarded at sea. The Protect Africa's Sawfishes project would be very grateful for any further donations of unused, point-and-shoot digital cameras to the project. They will all be passed on to fisheries and NGO staff who have received training and who show enthusiasm and interest in the project. Your donation might just encourage someone to take an interest in, and eventually conserve, sharks and rays in African waters!

Scientists document longest-ever case of sperm storage in sharks

SAN FRANCISCO (January 8, 2015) — Brownbanded bamboo sharks take the term “resourceful” to a whole new level. Steinhart Aquarium biologists at the California Academy of Sciences were taken aback when a shark egg case dropped by an adult bamboo shark showed signs of healthy development. The scientists had good reason for surprise: the aquarium’s female Chiloscyllium punctatum adults had spent nearly four years—45 months—in complete isolation from males.

When one viable egg resulted in the birth of a healthy pup, Academy scientists set out to examine this unprecedented example of sharks’ long-suspected (but little-documented) ability to store sperm over long periods of time. Their results, published in the Journal of Fish Biology, mark the longest documented case of sperm storage in any species of shark, and highlight a bright bit of news for the future of wild sharks threatened by overfishing and habitat loss.

“Long-term sperm storage—where a female can delay fertilization for months or even years after mating—is a remarkable adaptation that helps promote genetic diversity,” says Dr. Luiz Rocha, Academy Curator of Ichthyology. “In contrast, asexual reproduction produces offspring with very little genetic variation. Exploring the bamboo shark’s ability to store sperm gives us hope that wild sharks can help protect their population’s genetic diversity when mates are scarce and serious threats arise.”

The Academy’s scientific investigation began in 2010, when curious Academy biologist Nancy Sinai wondered whether any of the shark egg cases regularly found in the aquarium’s Shark Lagoon exhibit might be viable. Much like the hens that lay our breakfast eggs, many sharks are known to produce unfertilized eggs. Biologists transferred several brownish egg cases from the Lagoon into a separate incubator on public display, where two of the eggs showed signs of healthy embryonic development. While one egg failed to develop successfully, the other flourished. On January 21, 2012, a healthy bamboo shark pup emerged from its egg and began its life at the Academy’s Steinhart Aquarium.

A team of Academy scientists—including Rocha and Veterinarian Dr. Freeland Dunker—were left to investigate how this seemingly unlikely birth may have occurred in the absence of male sharks.

“It’s highly unlikely that the bamboo sharks mated with another individual in the aquarium,” says lead author Moisés A. Bernal, PhD candidate and researcher in the Academy’s Ichthyology Department. “All the other sharks in the Lagoon are female. There is one male Javanese cownose ray, but mating between sharks and rays is only a very remote possibility.”

Two guesses were more likely: either a female adult shark reproduced asexually in a process called “parthenogenesis” (as has been observed in four different shark species), or it had stored sperm from its last mating event several years before the fertilized egg appeared in the Lagoon. Aquarium records showed that the Academy’s three female bamboo sharks—each a possible mother to the new pup—had no contact with compatible males since their 2007 residence at the Aquarium of the Pacific in Southern California.

Armed with highly advanced genetic tools, scientists headed to the lab to solve the mystery of the brownbanded bamboo pup. Dunker and his veterinarian team removed tiny DNA-packed slivers from the fins of the pup and the three potential mothers during their annual physical exam. Researchers used this DNA to craft genetic profiles for each individual, and ran them through a series of genetic tests for comparison. In a strike against the asexual reproduction theory, the shark pup displayed comparable results with each female on a particular genetic test that looks at genetic variation within an individual. If the mother had reproduced asexually through parthenogenesis, the offspring would have shown less genetic variation than that of its mother.

The pup also displayed genetic material—in the form of 32 alleles, or parts of genes—absent from all three adult females. Study authors concluded that the young shark most likely inherited this “mystery” genetic material from its father—an unknown male from the long-ago tank at the Aquarium of the Pacific.

While the new study results are the first documentation of long-term sperm storage inC. punctatum, the advantageous adaptation has been observed in other sharks (and many other animals, including marsupials, insects, and frogs). After mating, some female sharks can store sperm in the tubules near their oviduct—an important reproductive area that helps produce the jelly-like substance that surrounds fertilized shark eggs.

The ability to store sperm gives females the power to produce young regardless of whether or not they are ovulating when mating occurs, and also means a potential pup will have unique genetic contributions from both its mother and its father. This type of genetic diversity is a boon for wild populations. Diversity is critical in maintaining the health of populations—especially those pared down by overfishing, environmental threats, and a lack of potential reproductive partners. Like a monoculture crop destroyed by a single pest species, populations that lack diversity are susceptible to widespread die-off in the face of significant threats.

“Questions remain,” adds Bernal, in reference to next research steps. “We know that several species of sharks have reproductive tactics like storing sperm or reproducing by parthenogenesis in the absence of males, but we need to know when and how these alternate techniques are triggered. Understanding these mechanisms—and how they impact genetic diversity—could be vital for the future of shark conservation.”
