Charlie Underwood sent us a message and asked us, if
"Shark-references" may know people who may be interested. David Ward and he have managed to obtain several jaws of Lamna nasus with data (North Sea). These are probably the last by catch landed under scientific licence before the complete EU ban. They will not sell these but will exchange them for other scientifically useful (modern, maybe fossil) material. If I know anyone interested, they can contact me. As these are CITES it will cost money for permits to ship outside the EU."
If you have interest please contact Charlie Underwood (c.underwood@bbk.ac.uk)

Attached is a small image of the teeth of the lower jaw of the largest (2.25m) male Lamna nasus.

New described species/Taxonomic News:



CICIMURRI, D.J. & EBERSOLE, J.A. (2015): Paleocene chimaeroid fishes (Chondrichthyes: Holocephali) from the eastern United States, including two new species of CallorhinchusPaleoBios, 32 (1): 1-29
New species: Callorhinchus phillipsi, Callorhinchus alfordi
Abstract: Isolated tooth plates collected from Paleocene deposits of Alabama, Arkansas, Illinois, Maryland, Mississippi, New Jersey, South Carolina, Texas, and Virginia represent four genera of chimaeroid fishes. Callorhinchus is reported in the fossil record of North America for the first time and is represented by material from the Danian (early Paleocene) of Mississippi and the Thanetian (late Paleocene) of Maryland and Virginia. Specimens from both locations are identified as new species, the Danian C. phillipsi n. sp. and the Thanetian C. alfordi n. sp. New PaleoceneElasmodus records from North America include two partial mandibulars belonging to E. hunteri from the Thanetian of Maryland, and a nearly complete mandibular from the Danian of New Jersey, tentatively assigned to cf. Elasmodus sp. Two species ofIschyodus are recognized, I. dolloi (Danian and Thanetian) and I. williamsae (Danian), but the two species have not been found in the same lithostratigraphic deposits.Edaphodon mirificus is known from the Danian of New Jersey and Mississippi, and the genus also occurs in the Thanetian of Virginia.



DONNELLAN, S.C. & FOSTER, R. & JUNGE, C. & HUVENEERS, C. & ROGERS, P. & KILIAN, A. & BERTOZZI, T. (2015): Fiddling with the proof: the  is a colour pattern variant of the common Southern Fiddler Ray (Rhinobatidae: Trygonorrhina).Zootaxa, 3981 (3): 367–384
New synonym: Trygonorrhina melaleuca synonym of Trygonorrhina dumerilii
Abstract: The Magpie Fiddler ray, Trygonorrhina melaleuca Scott 1954, is presently South Australia’s (SA) rarest fish, represented by only three museum specimens collected near Adelaide over the past 60 years and listed as Endangered in the IUCN Red List of Threatened Species. However, there is some doubt as to whether the Magpie Fiddler Ray is a different species from the widespread and common Southern Fiddler Ray, Trygonorrhina dumerilii (Castelnau 1873), resulting in two very contrasting scenarios for marine conservation. If the Magpie Fiddler Ray is a black and white patterned variant of the Southern Fiddler Ray then it will be removed from the Red List and appear as a synonym of T. dumerilii. Conversely, if it proves to be a different species then it remains SA’s rarest fish species and highly data deficient. We analysed mtDNA and the largest ever nuclear gene dataset (>4,000 loci) applied to chondrichthyan species level systematics from the most recently collected Magpie Fiddler Ray specimens and a geographically representative selection of Southern Fiddler Rays to determine the species status of this enigmatic ray. We found that the Magpie Fiddler Rays share a mitochondrial haplotype with 23 Southern Fiddler Rays and are not differentiated from 35 Southern Fiddler Rays at more than 4000 SNPs derived from DArTseq data. The morphological trait values that are putatively diagnostic for the Magpie Fiddler Ray fall within the range of variation observed among Southern Fiddler Rays. Our analyses are consistent with the notion that the Magpie Fiddler Ray is a rare colour and pattern variant of the widespread and abundant Southern Fiddler Ray. We also identified two hybrids between the Eastern and Southern Fiddler Rays, only the third time that hybrids have been identified in nature in chondrichthyans. Our results provide critical guidance in the assessment of its conservation status and an ending to a 60 year old conundrum for marine conservation.

WALOVICH, K.A. & EBERT, D.A. & LONG, D.J. & DIDIER, D.A. (2015):Redescription of Hydrolagus africanus (Gilchrist, 1922) (Chimaeriformes: Chimaeridae), with a review of southern African chimaeroids and a key to their identification. African Journal of Marine Science, 37 (2): 157-165
Redescription/new neotype
AbstractHydrolagus africanus (Gilchrist, 1922) is a little‑known chimaeroid species, originally described from the KwaZulu‑ Natal coast of South Africa, with a range spanning the western Indian Ocean from Kenya, south to Mozambique and South Africa, and extending into the south‑eastern Atlantic to Namibia. This species is characterised by a lateral patch of denticles on the male prepelvic tenacula, a second dorsal fin slightly indented in the centre, a long, curved dorsal spine equal to or sometimes exceeding the height of the first dorsal fin, and a uniform light brown body with no distinctive markings or patterns and slightly darker brown fins. To clarify the taxonomic status of H. africanus, we examined and compared specimens from throughout its range in southern Africa. Because the syntypes of H. africanus are lost, we designate a neotype and redescribe the species based on the neotype and additional southern African specimens. In addition, we present a review of southern African chimaeroids and provide an updated key to their identification.


UTEVSKY, A. & GORDEEV, I. (2015): New tentacled leech Ceratobdella quadricornuta n. g., n. sp (Hirudinida: Piscicolidae) parasitic on the starry skate Raja georgiana Norman from the Scotia Sea, Antarctica. Systematic Parasitology, 91 (3): 203-210
New genus: Ceratobdella
New species: Ceratobdella quadricornuta
Abstract: A new fish leech Ceratobdella quadricornuta n. g., n. sp. (Hirudinida: Piscicolidae), a parasite of the Antarctic skate Raja georgiana Norman (Rajiformes: Rajidae) collected between the Falkland Islands and South Georgia Island in the Scotia Sea, is described and compared with related genera. Ceratobdella quadricornuta is characterised by an uncommon appearance of its anterior sucker bearing four well-developed tentacles and a unique combination of features of the reproductive and digestive systems: crop and intestine equally developed, posterior crop caeca separated; accessory glands, conductive tissue and external copulatory area lacking; common part of ejaculatory ducts (common atrium) voluminous and muscular, male copulatory bursa short, small ovisacs opening into female copulatory bursa (vagina).

Why do these sharks glow in the dark?

Creatures that dwell hundreds of meters below the ocean’s surface are notoriously strange and alluring, and the lanternshark is no exception. Mysterious fluorescent markings, called lateral photophores, flank both sides of the small, slender shark’s body, glowing vibrantly in waters that are otherwise black (pictured).

Exit dinosaurs, enter fishes

Mass extinction event that killed the dinosaurs gave rise to modern 'age of fishes'

A pair of paleobiologists have determined that the world's most numerous and diverse vertebrates -- ray-finned fishes -- began their ecological dominance of the oceans 66 million years ago, aided by the mass extinction event that killed off dinosaurs.

To avoid dangerous shark encounters, information trumps culling

Risk of great white shark attack in California waters down 91 percent since 1950, researchers report

The risk of white shark attack for individual ocean users in California has fallen strikingly, by over 91 percent, since 1950, California scientists have found. Information that empowers ocean users to avoid the large predators is far more effective for public safety than culling sharks.
