PHYLOGENETIC RELATIONSHIPS AMONG THE CIRRATE OCTOPODS (MOLLUSCA: Cephalopoda) were investigated using partial sequences of the 16S rRNA mitochondrial gene. The derived phylogeny supports the traditional separation of cirrate families based on web form. Genera with a single web (Opisthoteuthis, Grimpoteuthis, Luteuthis, and Cirroctopus) are clearly distinct from those with an intermediate or secondary web (Cirroteuthis, Cirrothauma, and Stauroteuthis). The cirrates with a single web are… 
A combined approach to the phylogeny of Cephalopoda (Mollusca)
TLDR
This study provides a comprehensive phylogenetic analysis of Cephalopoda (Mollusca) using a combination of molecular and morphological data, finding Vampyromorpha formed the sister group to Decabrachia under the majority of parameters.
TAXONOMY, ECOLOGY AND BEHAVIOUR OF THE CIRRATE OCTOPODS
TLDR
The data on reproductive biology indicate that spawning is extended, with growth continuing during a reproductive period that probably occupies much of the life cycle, an unusual strategy in cephalopod molluscs.
Molecular phylogeny of coleoid cephalopods (Mollusca: Cephalopoda) inferred from three mitochondrial and six nuclear loci: a comparison of alignment, implied alignment and analysis methods
TLDR
It is demonstrated how differences in alignment and analysis methods commonly used in cephalopod phylogenetics can lead to different, but often highly supported, relationships.
Genus-level phylogeny of cephalopods using molecular markers: current status and problematic areas
TLDR
This study identifies unresolved phylogenetic relationships within the cephalopod phylogeny and insufficient taxonomic sampling among squids excluding the Loliginidae in the Decabrachia and within the Order Cirromorphida in the OctobRachia.
Flapjack devilfish in the northern North Atlantic: morphology, biology and ecology of Opisthoteuthis borealis (Cephalopoda, Octopoda, Cirrata)
TLDR
Despite the assumption that Cirrata feed on relatively small prey only, large mature males of O. borealis consume polychaetes reaching 41.5–45.9% ML of the specimens, suggesting well-developed regeneration is present even in this ancient taxon of cephalopods.
Identification of ommastrephid squid paralarvae collected in northern Hawaiian waters and phylogenetic implications for the family Ommastrephidae using mtDNA analysis
TLDR
Although the phylogenetic relationships among genera were not resolved well due to apparent homoplasy and large genetic divergence between species, COI sequence data without transitions provided support for subfamily level relationships.
The genus Grimpoteuthis (Octopoda: Grimpoteuthidae) in the north-east Atlantic, with descriptions of three new species
The systematics and distribution of the cirrate octopod genus Grimpoteuthis in the north-east Atlantic are reviewed. Three new species are described and Grimpoteuthis wuelkeri (Grimpe, 1920) is
Morphology, biology and molecular characterizations of Opisthoteuthis calypso (Cephalopoda: Octopoda) from the Sardinian Channel (central western Mediterranean)
TLDR
Morphological variability and the peculiar structure of the shell and beak are reported and discussed, and the biological characteristics of the Sardinian samples are compared to those of other Mediterranean and Atlantic samples.
Novel insights into early life stages of finned octopods (Octopoda: Cirrata)
The finned or dumbo octopods (Octopoda: Cirrata) constitute a cephalopod (Mollusca: Cephalopoda) taxon almost exclusively comprising organisms that inhabit the deep-sea. This renders studying the
Morphological and genetic differentiation of two loliginid squids, Uroteuthis (Photololigo) chinensis and Uroteuthis (Photololigo) edulis (Cephalopoda: Loliginidae), in Asia
TLDR
The taxonomic status of the two species in East Asia was elucidated by morphological and genetic analyses, indicating that U. (P.) edulis and U.(P.) chinensis are distinct species.

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
Phylogeny of decapod cephalopods based on partial 16S rDNA nucleotide sequences.
TLDR
The 3' end of 16S rDNA gene of cephalopods is a precious tool to analyze taxonomic relationships at the infrafamilial level and a gene with a lower evolutionary rate, is necessary to establish higher taxa phylogeny.
Systematics, distribution and biology of the cirrate octopods of the genus Opisthoteuthis (Mollusca, Cephalopoda) in the Atlantic Ocean, with description of two new species
TLDR
The systematics of the deep-sea cirrate octopod genus Opisthoteuthis Verrill in the Atlantic Ocean is reviewed and two new species, O. calypso and O. hardyi, known only from a single specimen from the SW Atlantic are described.
A revision of the family Stauroteuthidae (Octopoda: Cirrata) with redescriptions of Stauroteuthis syrtensis and S. gilchristi
The cirrate octopod family Stauroteuthidae is revised on the basis of new material collected from the North and South Atlantic and a thorough examination of relevant type material. The family is
A new species of Luteuthis (Mollusca: Cephalopoda: Octopoda: Cirrata) from the South China Sea
TLDR
It is suggested that G. tuftsi be placed in the family Luteuthidae, but because of a lack of adequate comparative material, no formal action is taken to prescribe it to a new genus.
The genus Grimpoteuthis (Octopoda: Grimpoteuthidae) in the north-east Atlantic, with descriptions of three new species
The systematics and distribution of the cirrate octopod genus Grimpoteuthis in the north-east Atlantic are reviewed. Three new species are described and Grimpoteuthis wuelkeri (Grimpe, 1920) is
Distribution of deep-water benthic and bentho–pelagic cephalopods from the north-east Atlantic
The distribution of deep-water (150–4850 m) benthic and bentho–pelagic cephalopods in the north-east Atlantic is described, based on 592 specimens collected from commercial and research trawling.
Subtle population structuring within a highly vagile marine invertebrate, the veined squid Loligo forbesi, demonstrated with microsatellite DNA markers
TLDR
The demonstration of genetic subdivision in an abundant, highly mobile marine invertebrate has implications for the interpretation of dispersal and population dynamics, and consequent management, of such a commercially exploited species.
Cirrothauma murrayi chun, a finned octopod
TLDR
Cirrothauma, like other cirrates, thus shows some features that are present in Vampyroteuthis, and others that are found in decapods, as well as many present in the octopods without fins, which represent in some ways an early condition of the coleoid stock.
CONFIDENCE LIMITS ON PHYLOGENIES: AN APPROACH USING THE BOOTSTRAP
  • J. Felsenstein
  • Biology, Medicine

  • 1985
TLDR
The recently‐developed statistical method known as the “bootstrap” can be used to place confidence intervals on phylogenies and shows significant evidence for a group if it is defined by three or more characters.
