The tools of molecular genetics have enormous potential for clarifying the nature and age of species boundaries in marine organisms. Below I summarize the genetic implications of various species concepts, and review the results of recent molecular genetic analyses of species boundaries in marine microbes, plants, invertebrates and vertebrates. Excessive lumping, rather than excessive splitting, characterizes the current systematic situation in many groups. Morphologically similar species are… 
Hitchhiking the high seas: Global genomics of rafting crabs
TLDR
The results of this study provide unprecedented resolution of the systematics and global biogeography of this group and contribute valuable information to the understanding of how theoretical dispersal potential relates to actual population differentiation and diversification among marine organisms.
Cryptic speciation on the high seas; global phylogenetics of the copepod family Eucalanidae
  • E. Goetze
  • Biology, Environmental Science
    Proceedings of the Royal Society of London. Series B: Biological Sciences
  • 2003
TLDR
A phylogenetic study of the oceanic copepod family Eucalanidae was undertaken to develop a model zooplankton taxon in which speciation events can be confidently identified, suggesting that continental landmasses form barriers to dispersal for a subset of circumglobal species.
Evolution and biodiversity of Antarctic organisms: a molecular perspective
  • A. Rogers
  • Environmental Science, Biology
    Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2007
TLDR
Genetic studies have revealed that species defined by morphological characters are complexes of cryptic or sibling species, which is consistent with the diversity and distribution of marine and terrestrial taxa having been strongly influenced by geological and climatic cooling events over the last 70 years.
Genetic evidence for an undescribed species previously considered as Sillago sihama from the northern Red Sea
TLDR
This study sequenced a 655-bp region of the mitochondrial cytochrome c oxidase subunit I gene from Hong Kong, southern Red Sea and Mediterranean populations of Sillago and found it to be identical to that of the Mediterranean population, confirming the existence of two distinct species.
A Tri-Oceanic Perspective: DNA Barcoding Reveals Geographic Structure and Cryptic Diversity in Canadian Polychaetes
TLDR
The consistent geographic structuring within presumed widespread species suggests that historical range fragmentation during the Pleistocene ultimately increased Canadian polychaete diversity and that the coastal British Columbia fauna played a minor role in Arctic recolonization following deglaciation.
Dispersal and gene flow in free-living marine nematodes
Dispersal and gene flow determine connectivity among populations, and can be studied through population genetics and phylogeography. We here review the results of such a framework for free-living
Species discovery in marine planktonic invertebrates through global molecular screening
TLDR
It is shown that for taxonomic groups with poorly characterized systematics, large‐scale genetic screening using a mitochondrial DNA marker can be a very effective approach to species discovery through large-scale sampling of mitochondrial diversity.
SPECIATION IN ANCIENT CRYPTIC SPECIES COMPLEXES: EVIDENCE FROM THE MOLECULAR PHYLOGENY OF BRACHIONUS PLICATILIS (ROTIFERA)
TLDR
Analysis of rotifer resting eggs from 27 salt lakes in the Iberian Peninsula plus lakes from four continents revealed nine genetically divergent lineages and sequence divergence estimates indicate that the B. plicatilis complex began diversifying many millions of years ago, yet has showed relatively high levels of morphological stasis.
Hidden diversity in the genus Tethya: comparing molecular and morphological techniques for species identification
TLDR
This study supports the notion that cryptic speciation in sponges may go undetected and diversity underestimated when using only morphology-based taxonomy, which has broad scale implications for conservation and management of marine systems.
SOUTHERN HOSPITALITY: A LATITUDINAL GRADIENT IN GENE FLOW IN THE MARINE ENVIRONMENT
  • R. Kelly, D. Eernisse
  • Environmental Science, Biology
    Evolution; international journal of organic evolution
  • 2007
TLDR
Analysis of original mitochondrial DNA data from 969 individuals representing 28 chiton (Mollusca: Polyplacophora) species reveals a distinct latitudinal connectivity gradient among chitons, which may contribute to the increased species diversity observed at lower latitudes.

Species of marine invertebrates: a comparison of the biological and phylogenetic species concepts
TLDR
In groups with extensive dispersal ability, there may be predictable relationships between genetic and reproductive divergence that allow taxonomic decisions to be made using either species concept, although evidence for this in the field is limited.
Genetic divergence and geographic diversification in Nautilus
TLDR
DNA sequence analysis indicates that there are three geographically distinct clades consisting of western Pacific, eastern Australian/Papua-New Guinean, and western Australian/Indonesian forms, and morphologically and genetically distinct species Nautilus scrobiculatus falls outside the three geographically recognized assemblages.
Genetic structure of coral reef organisms: Ghosts of dispersal past
TLDR
The genetic structure of populations is likely to have been maintained for several thousand years after they were first established, during or immediately after range expansion, by the occurrence of co-adapted gene complexes of some form, and because of more limited opportunity for dispersal than has been assumed to date.
Genetic Divergence, Reproductive Isolation, and Marine Speciation
TLDR
Such studies show how a focus on the physiology, ecology, or sensory biology of reproductive isolation can help uncover the influence of particular genetic changes on reproductive isolation for marine (or terrestrial) taxa.
The General Lineage Concept of Species, Species Criteria, and the Process of Speciation
TLDR
This chapter provides a general theoretical context that accounts for both the unity and the diversity of ideas represented by alternative species definitions, and proposes a revised and conceptually unified terminology for the ideas described by contemporary species definitions.
Population structure in the American oyster as inferred by nuclear gene genealogies.
TLDR
No simple explanation can account for the great variety of population genetic patterns across loci displayed by American oysters, and this study provides an empirical demonstration that different sequences of DNA within the same organismal pedigree can have quite different phylogeographic histories.
Stock structure analysis and species identification
TLDR
Currently available information on species identity and stock structure in the genus Illex, using predominantly ecological, parasitological, molecular genetic and morphometric data is considered, indicating a complex relationship between dispersal capacity, gene flow and population differentiation in these animals.
Hidden diversity in marine algae: Some examples of genetic variation below the species level
TLDR
A number of examples from marine algae in which allozymes, DNA sequences and RAPDs are used to identify cryptic species and explore phylogenetic-population level relationships over several biogeographic spatial and temporal scales are presented.
HYBRIDIZATION FREQUENCY IS NEGATIVELY CORRELATED WITH DIVERGENCE TIME OF MITOCHONDRIAL DNA HAPLOTYPES IN A SEA STAR (LEPTASTERIAS SPP.) SPECIES COMPLEX
  • D. Foltz
  • Biology
    Evolution; international journal of organic evolution
  • 1997
TLDR
The existence of numerous sympatric and closely related haplotypes within the Leptasterias cryptic species complex offered the possibility of studying the occurrence of hybridization between haplotypes in more detail, and genetic cohesiveness of each of the five most common and broadly distributed haplotypes was demonstrated.
No clear genetic distinction between morphological species within the coral genus Platygyra
TLDR
Genotypic frequencies in the three morphological species and in pooled samples of all taxa, deviated significantly from Hardy-Weinberg equilibrium, indicating mating was not entirely random in these groups.
