“…Molecular tools have prompted the recognition of distinct lineages even among large, well‐studied predators such as the Scalloped hammerhead shark ( Sphyrna lewini , Sphyrnidae) (Table ; Quattro et al . ). In total, molecular evaluations have led to the division of five previously circumtropical species into multiple taxa and subsequent removal from the list (Tables and S2).…”

“…Indeed, several circumtropical species have been subdivided when two or more genetic lineages were detected and the species was subsequently reexamined using morphology (e.g. Bowen et al 2008;Durand et al 2012;Quattro et al 2013). The application of DNA barcoding to fishes (Ward et al 2005) and the subsequent establishment of public depositories for DNA sequences provide a new data source to explore the cohesiveness of circumtropical species.…”

Fishes that rule the world: circumtropical distributions revisited

et al. 2015

Briggs (1960) published the first checklist of circumtropical fishes with 107 species. This work served for a half century as the most comprehensive checklist of globally distributed fishes, but the intervening years witnessed many discoveries, and molecular data have changed the way we evaluate species. Here, we update the list guided by taxonomic revisions, phylogenies, phylogeographic data and DNA barcodes. The resulting list now includes 284 species. The dramatic increase is primarily due to two trends: (i) continued oceanic exploration leading to range revisions and species discoveries and (ii) public databases such as FishBase and the Catalogue of Fishes make range data more accessible. Five species were removed from the list as closer scrutiny revealed multiple taxa, 14 were removed due to updated range information, and 35 more are suspected to be species complexes. The species listed here are mostly pelagic and bathypelagic fishes. Euryhaline, anadromous, catadromous, freshwater, and with few exceptions, reef fishes do not achieve global distributions. The most species-rich family of marine fishes (Gobiidae) is absent. The fishes with the longest pelagic larval stage (Anguillidae) are absent. In contrast, requiem sharks (Carcharhinidae), tunas (Scombridae), jacks (Carangidae), remoras (Echeneidae) and especially lanternfishes (Myctophidae) have multiple representatives. The combined evidence indicates that high mobility as an adult is a key requirement to achieve a global distribution. Many others are members of monotypic genera or families, indicating old lineages that did not diversify. We conclude that global ranges may promote persistence over evolutionary timescales, but also reduce opportunities for speciation.

“…Approximately 1120 base pairs (bp) of the 5 0 end of the mtDNA CR was amplified for C. limbatus, C. sorrah, and R. acutus using the forward primer ProL2 and the reverse primer PheCa-caH2 (Pardini et al 2001). A different primer set was used for S. lewini to identify potential specimens of the recently described cryptic species S. gilberti (Quattro et al 2013). The forward primer CRF6 and the reverse primer CRR10 (Pinhal et al 2012) were shown to clearly distinguish between the two species and were hence used in our study to amplify approximately 700 bp of the initial portion of the mtDNA CR for all S. lewini specimens.…”

Population genetics of four heavily exploited shark species around the Arabian Peninsula

The northwestern Indian Ocean harbors a number of larger marine vertebrate taxa that warrant the investigation of genetic population structure given remarkable spatial heterogeneity in biological characteristics such as distribution, behavior, and morphology. Here, we investigate the genetic population structure of four commercially exploited shark species with different biological characteristics (Carcharhinus limbatus, Carcharhinus sorrah, Rhizoprionodon acutus, and Sphyrna lewini) between the Red Sea and all other water bodies surrounding the Arabian Peninsula. To assess intraspecific patterns of connectivity, we constructed statistical parsimony networks among haplotypes and estimated (1) population structure; and (2) time of most recent population expansion, based on mitochondrial control region DNA and a total of 20 microsatellites. Our analysis indicates that, even in smaller, less vagile shark species, there are no contemporary barriers to gene flow across the study region, while historical events, for example, Pleistocene glacial cycles, may have affected connectivity in C. sorrah and R. acutus. A parsimony network analysis provided evidence that Arabian S. lewini may represent a population segment that is distinct from other known stocks in the Indian Ocean, raising a new layer of conservation concern. Our results call for urgent regional cooperation to ensure the sustainable exploitation of sharks in the Arabian region.

“…To investigate nursery habitat usage of two sympatrically distributed sphyrnids, the scalloped hammerhead Sphyrna lewini (Griffith & Smith 1834) and the recently discovered Carolina hammerhead Sphyrna gilberti Quattro, Driggers III, Grady, Ulrich & Roberts 2013, double‐digest restriction associated DNA sequencing (ddRAD) was used to identify a panel of single nucleotide polymorphisms (SNP) that can be used to differentiate between the species. Because S. lewini and S. gilberti are conserved morphologically and differ only in the number of precaudal vertebrae (Quattro et al ., ), the panel allows for conclusive, non–lethal species identification.…”

Identification of young‐of‐the‐year great hammerhead shark Sphyrna mokarran in northern Florida and South Carolina

Two sharks, visually identified in the field as young-of-the-year (YOY) scalloped hammerhead Sphyrna lewini, were identified as great hammerhead Sphyrna mokarran based on nuclear-encoded single nucleotide polymorphisms (SNP) and sequences of mtDNA. Individuals were captured and released in Bulls Bay, SC, and Saint Joseph Bay, FL, in 2013 and 2014, respectively. These findings indicate S. mokarran may be pupping in or around these areas and highlight new regions that may be a productive focus for future research on early life history of S. mokarran.
