“…This is in line with the results of several recent studies which suggested that many widespread marine invertebrates taxa comprise genetically divergent cryptic species (Sponer and Roy 2002;Moura et al 2008;Chen and Hares 2011). Additionally, in the order Amphipoda, cryptic speciation has been widely reported, especially for gammarids (Costa et al 2009;Radulovici et al 2009;Baird et al 2011). In this sense, the study carried out by Pilgrim and Darling (2010) is particularly interesting because it provides molecular evidence of cryptic speciation in two introduced biofouling amphipods along the Pacific North American coast (COI genetic divergence ranged from 4.4 to 14 %).…”

Long-distance dispersal, low connectivity and molecular evidence of a new cryptic species in the obligate rafter Caprella andreae Mayer, 1890 (Crustacea: Amphipoda: Caprellidae)

et al. 2012

The amphipod Caprella andreae Mayer, 1890 was recorded for the first time in Southern Iberian Peninsula (36°44 0 15 00 N, 3°59 0 38 00 W). This species is the only obligate rafter of the suborder Caprellidea and has been reported to attach not only to floating objects such as ropes or driftwoods but also to turtle carapaces. Mitochondrial and nuclear markers were used to examine dispersal capabilities and population genetic structure of C. andreae across seven localities in the Mediterranean and Atlantic Ocean collected from floating substrata with different dispersal patterns. The strong population differentiation with no haplotypes shared between populations suggests that C. andreae is quite faithful to the substratum on which it settles. In addition, the proportionally higher genetic diversity displayed in populations living on turtles as well as the presence of highly differentiated haplotypes in the same turtle population may be indicative that these populations survive longer, which could lead C. andreae to prefer turtles instead of floating objects to settle and disperse. Therefore, rafting on floating objects may be sporadic, and ocean currents would not be the most important factor shaping patterns of connectivity and population structure in this species. Furthermore, molecular phylogenetic analyses revealed the existence of a cryptic species whose estimates of genetic divergence are higher than those estimated between C. andreae and other congeneric species (e.g. Caprella dilatata and Caprella penantis). Discovery of cryptic species among widely distributed small marine invertebrates is quite common and, in this case, prompts for a more detailed phylogenetic analysis and taxonomic revision of genus Caprella. On the other hand, this study also means the first record of the gammarids Jassa cadetta and Elasmopus brasiliensis and the caprellid Caprella hirsuta on drifting objects.

“…It is therefore recommended that an integrative taxonomic approach should be conducted whenever possible. Our results are in large agreement with the general performance of DNA barcoding data in marine metazoans (Bucklin et al 2011), crustaceans (Costa et al 2007) including marine amphipods and demonstrated the identification potential of an integrative approach combining morphology and genetics (Radulovici et al 2009;Havermans et al 2010Havermans et al , 2011). …”

Fishing for scavengers: an integrated study to amphipod (Crustacea: Lysianassoidea) diversity of Potter Cove (South Shetland Islands, Antarctica)

et al. 2017

Amphipoda from the superfamily Lysianassoidea Dana, 1849 play an important role in Southern Ocean benthic food webs due to their high biomass, abundance and predominantly scavenging mode of feeding. Our knowledge on the lysianassoid fauna, even in well-studied areas of the Western Antarctic Peninsula, is incomplete. Here we report the findings of an integrated study of lysianassoid amphipods of Potter Cove, King George Island/ Isla 25 de Mayo (KGI), combining morphological and molecular species identification (COI barcoding) methods, investigating more than 41,000 specimens from baited traps. For comparison, 2039 specimens from the adjacent Marian Cove were analysed. Ten lysianassoid species were recorded in the deeper outer Potter Cove, whereas the inner cove (<50 m) was dominated by a single species, Cheirimedon femoratus Pfeffer, 1888 (99.44% relative abundance). It is hypothesized that the impoverished lysianassoid fauna inside the meltwater-influenced inner cove represents a 1model for future conditions along the Western Antarctic Peninsula under conditions of increased glacial melting. 2Abyssorchomene charcoti (Chevreux, 1912)

“…To illustrate, Shih et al (2009) used genetic barcodes to distinguish six species of fiddler crabs of the genus Uca in the Indian Ocean. In another study, Radulovici et al (2009) barcoded 87 crustacean species, most of which were shrimps, and the study showed the utility of the barcoding approach in diagnosing marine crustaceans. Genetic barcoding can also be particularly useful for identifying marine invertebrate juveniles and larvae, which are difficult to distinguish morphologically.…”

DNA barcoding of twelve shrimp species (Crustacea: Decapoda) from Turkish seas reveals cryptic diversity

et al. 2014

DNA barcoding is a useful tool for the identification and potential discovery of new species. In this study, DNA barcoding was employed by sequencing the mitochondrial cytochrome oxidase subunit I gene (COI) to characterize the genetic diversity of 12 shrimp species inhabiting Turkish coastal waters and, when possible, to compare with the genetic data available from different parts of the Mediterranean and eastern Atlantic. This study also comprises the first DNA barcoding study performed in the Turkish Seas using COI. A total of 40 shrimp specimens were collected and analyzed from 9 sites. Generally, the barcoding gap criterion was successful in identifying species; hence, COI appeared to be a good marker of choice for DNA barcoding in this group. Out of the 12 species investigated, five were barcoded for the first time. For six species, two intraspecific clades were retrieved after the analyses. The results suggest the presence of cryptic diversity in a genetically understudied marine area, the Turkish coastal waters, and further investigation of these species using population genetics, taxonomic approaches and nuclear markers is likely to result in designation of new species.
