“…Fossil, morphological and molecular data support the hypothesis that mobulids are one of the most derived groups of elasmobranchs and closely related to rhinopterids (cownose rays, genus Rhinoptera) within a polyphyletic clade of Myliobatidae Aschliman et al, 2012a;Claeson et al, 2010;De Carvalho et al, 2004;Dunn et al, 2003;Lovejoy, 1996;McEachran and Aschliman, 2004;McEachran et al, 1996;Nishida, 1990;Shirai, 1996). However, a sister-clade relationship to a myliobatid-rhinopterid clade has also been proposed (Gonzalez-Isais and Dominguez, 2004) solely based on morphological data.…”

“…This pattern is most notable in Clades II and III; however, a similar pattern is repeated in Clade I, where early radiations within the clade between 19 and 17 Mya are followed by long interior branches and the subsequent diversification of Manta less than 1 Mya. Punctuated patterns are common across the Tree of Life, including all major lineages of batoid rays (Aschliman et al, 2012a). Rapid radiations are often associated with key innovations, meta-community dynamics, environmental change and/or accelerated rates of molecular evolution (reviewed by Crisp and Cook, 2009).…”

“…In that case, the fossil record, in combination with correlations between phylogenetic topologies and paleo-climatic events can provide clues about possible drivers of the observed pattern. For example, Aschliman et al (2012a) attributed the pattern observed in the batoid ray phylogeny to an extinction event around the K/T boundary, owing to the higher survival rate of older lineages (families) relative to internal branches (genera).…”

“…Most notably, and despite the formal separation into Manta and Mobula, it has been suggested that Manta is nested within the genus Mobula (reviewed by Aschliman, 2014). This is based on the analysis of three out of 11 mobulids with the mitochondrial genes NADH2 and NADH4, and the nuclear genes RAG1 and SCFD2 (Aschliman et al, 2012a), and an analysis of six out of 11 mobulids with the mitochondrial gene NADH2 ; morphology (Adnet et al, 2012;Aschliman et al, 2012b;Gonzalez-Isais and Dominguez, 2004;Herman et al, 2000); and parasite evolution (Benz and Deets, 1988;Olson et al, 2010). Additionally, for several species it is still not clear whether they comprise distinct lineages or merely represent geographically separated morphological variants of the same species (Marshall and Bennett, 2010;Notarbartolo di Sciara, 1987).…”

a b s t r a c tManta and devil rays are an iconic group of globally distributed pelagic filter feeders, yet their evolutionary history remains enigmatic. We employed next generation sequencing of mitogenomes for nine of the 11 recognized species and two outgroups; as well as additional Sanger sequencing of two mitochondrial and two nuclear genes in an extended taxon sampling set. Analysis of the mitogenome coding regions in a Maximum Likelihood and Bayesian framework provided a well-resolved phylogeny. The deepest divergences distinguished three clades with high support, one containing Manta birostris, Manta alfredi, Mobula tarapacana, Mobula japanica and Mobula mobular; one containing Mobula kuhlii, Mobula eregoodootenkee and Mobula thurstoni; and one containing Mobula munkiana, Mobula hypostoma and Mobula rochebrunei. Mobula remains paraphyletic with the inclusion of Manta, a result that is in agreement with previous studies based on molecular and morphological data. A fossil-calibrated Bayesian random local clock analysis suggests that mobulids diverged from Rhinoptera around 30 Mya. Subsequent divergences are characterized by long internodes followed by short bursts of speciation extending from an initial episode of divergence in the Early and Middle Miocene (19-17 Mya) to a second episode during the Pliocene and Pleistocene (3.6 Mya -recent). Estimates of divergence dates overlap significantly with periods of global warming, during which upwelling intensity -and related high primary productivity in upwelling regions -decreased markedly. These periods are hypothesized to have led to fragmentation and isolation of feeding regions leading to possible regional extinctions, as well as the promotion of allopatric speciation. The closely shared evolutionary history of mobulids in combination with ongoing threats from fisheries and climate change effects on upwelling and food supply, reinforces the case for greater protection of this charismatic family of pelagic filter feeders.

“…The libraries were subsequently pooled in equimolar ratios for 100-bp paired-end sequencing using an Illumina MiSeq Benchtop Sequencer (Illumina). The mitochondrial sequence of one G. fowlerae (GN1363) specimen was also determined using PCR with overlapping primers and Sanger sequencing following the method of Aschliman et al (34) to validate the accuracy of sequence collected by our target capture method. To compare with the mitochondrial data, we also collected sequences of nuclear protein-coding genes for representatives of the major Glyphis lineages following the targeted nuclear gene capture protocol of Li et al (13).…”

For over a hundred years, the "river sharks" of the genus Glyphis were only known from the type specimens of species that had been collected in the 19th century. They were widely considered extinct until populations of Glyphis-like sharks were rediscovered in remote regions of Borneo and Northern Australia at the end of the 20th century. However, the genetic affinities between the newly discovered Glyphis-like populations and the poorly preserved, original museum-type specimens have never been established. Here, we present the first (to our knowledge) fully resolved, complete phylogeny of Glyphis that includes both archival-type specimens and modern material. We used a sensitive DNA hybridization capture method to obtain complete mitochondrial genomes from all of our samples and show that three of the five described river shark species are probably conspecific and widely distributed in Southeast Asia. Furthermore we show that there has been recent gene flow between locations that are separated by large oceanic expanses. Our data strongly suggest marine dispersal in these species, overturning the widely held notion that river sharks are restricted to freshwater. It seems that species in the genus Glyphis are euryhaline with an ecology similar to the bull shark, in which adult individuals live in the ocean while the young grow up in river habitats with reduced predation pressure. Finally, we discovered a previously unidentified species within the genus Glyphis that is deeply divergent from all other lineages, underscoring the current lack of knowledge about the biodiversity and ecology of these mysterious sharks.freshwater sharks | DNA | museum specimens
