  author={Annie R. Lindgren and Gonzalo Giribet and Michelle K. Nishiguchi},
Cephalopoda represents a highly diverse group of molluscs, ranging in habitat from coastal regions to deep benthic waters. While cephalopods remain at the forefront of modern biology, in providing insight into fields such as neurobiology and population genetics, little is known about the relationships within the group. This study provides a comprehensive phylogenetic analysis of Cephalopoda (Mollusca) using a combination of molecular and morphological data. Four loci (three nuclear 18S rRNA… 

Molecular phylogeny of coleoid cephalopods (Mollusca: Cephalopoda) inferred from three mitochondrial and six nuclear loci: a comparison of alignment, implied alignment and analysis methods

It is demonstrated how differences in alignment and analysis methods commonly used in cephalopod phylogenetics can lead to different, but often highly supported, relationships.

DNA barcoding analysis of Coleoidea (Mollusca: Cephalopoda) from Chinese waters

The efficacy of DNA barcoding for identifying species as well as discovering cryptic diversity of Chinese coleoids is confirmed and lays a foundation for other ecological and biological studies of Coleoidea.

A Preliminary Cephalopod Baraminology Study Based on the Analysis of Mitochondrial Genomes and Morphological Characteristics

The genome analysis study was augmented with the analysis of two morphological character sets which, when combined cover 72 cephalopod species, even fossil taxa which represent the palaeobaramin, and suggests that Decapods and Octopods each form a single holobaramin within the class Cephalopsoda.

A mitochondrial phylogeny of the family Onychoteuthidae Gray, 1847 (Cephalopoda: Oegopsida)

Results support monophyly for the family and all seven onychoteuthid genera (including Moroteuthopsis, established herein as the senior genus name for species formerly attributed to Kondakovia); 29 genetically distinct species were recovered, with the BIN analysis for COI showing good congruence overall with morphological species groupings.

Genetic diversity of isolated populations of Nautilus pompilius (Mollusca, Cephalopoda) in the Great Barrier Reef and Coral Sea

The differentiation of the Nautilus populations from the Northern section of the Great Barrier Reef and those from the Coral Sea were supported by two distinctly different methodologies and the significance of this separation and the potential evolutionary divergence of these two population groups is discussed.

Title A multigene phylogeny of Cephalopoda supports convergent morphological evolution in association with multiple habitat shifts in the marine environment Permalink

This study presents the first statistical tests for correlation between convergent traits and habitat in cephalopods to better understand the evolutionary history of characters that are adaptive in benthic or pelagic environments, respectively and supports the hypothesis that habitat has influenced convergent evolution in the marine environment.



Towards a phylogeny of gastropod molluscs: an analysis using morphological characters

This is one of the first attempts to use Morphological and developmental characters to assess the relationships of all major clades using parsimony methods and discusses the major monophyletic groups within gastropods.

Phylogeny of cephalopods inferred from mitochondrial DNA sequences.

The monophyly of the Decapoda and of each family is confirmed, and a high hierarchical rank for sepiolids appears justified; the order Sepioidea comprising five families should be abandoned, with Spirula being excluded.

A molecular phylogeny of the Octopoda (Mollusca: Cephalopoda) evaluated in light of morphological evidence.

In this paper we examine the phylogenetic relationships of the Octopoda utilizing molecular sequence data from the cytochrome c oxidase subunit I (COI) gene and compare results from analyses of

The evolution of coleoid cephalopods and their present biodiversity and ecology

The roles that transitions between pelagic and benthic habitats played in the evolution of cephalopods are noted, and the possibility is advanced that the most recent "oceanic anoxic event" may have established a time marker for the divergence of some oegopsid families.

On bivalve phylogeny: a high‐level analysis of the Bivalvia (Mollusca) based on combined morphology and DNA sequence data

Abstract. Bivalve classification has suffered in the past from the crossed-purpose discussions among paleontologists and neontologists, and many have based their proposals on single character

Towards a phylogeny of chitons (Mollusca, Polyplacophora) based on combined analysis of five molecular loci

The results refute several aspects of conventional classifications of chitons that are based primarily on shell characters, reinforcing the idea that chiton classification should be revised using additional characters.

Phylogeny of Henicopidae (Chilopoda: Lithobiomorpha): a combined analysis of morphology and five molecular loci

Morphology, as well as the most congruent parameters for the sequence data and combined analysis, resolved Zygethobiini within Henicopini, and Biogeographic analysis of subtrees for Paralamyctes resolved the interrelationships of Gondwana.

Biodiversity and systematics in cephalopods: unresolved problems require an integrated approach

No single organ/system-of-organs nor single methodology currently exists that will solve every problem in taxonomy, so an integrated approach, based on analysis of as many organs and different taxa as possible, is necessary to construct an accurate picture.

First molecular evidence for the existence of a Tardigrada + Arthropoda clade.

The results obtained represent the first molecular evidence for a Tardigrada + Arthropoda clade and indicate the need to review those obtained solely on morphological characters.

Actin gene family evolution and the phylogeny of coleoid cephalopods (Mollusca: Cephalopoda).

Phylogenetic analysis conducted on a 784-bp fragment of 82 actin gene sequences of 44 coleoid cephalopod taxa confirmed the presence of at least three distinct actin loci in coleoids, suggesting at least two independent derivations of muscle actins in the protostome lineage, although statistical support for this conclusion was lacking.
