The full mitochondrial genome sequence of the greater argonaut Argonauta argo (Cephalopoda, Argonautoidea) and its phylogenetic position in Octopodiformes [PDF]
Mitochondrial DNA. Part B. Resources, 2021 The greater argonaut Argonauta argo is a species of the paper nautilus (Argonautidae), which is a family in Octopoda. In this paper, we report its full mitogenome sequence, which was obtained from a specimen collected in the Japan Seas near Oki Island ...

Topographical distribution of visual cell nuclei in the retina in relation to the habitat of five species of Decapodiformes (Cephalopoda) [PDF]
Journal of Molluscan Studies, 2010 Studies of retinal histology of fish have established that the position of an area of high cell density reflects both the habitat and feeding behaviour. Here, we discuss potential relationships between biology, specifically behaviour and ecology, and visual axes (estimated from density of visual cell nuclei) in five species of Decapodiformes.

O enigma da "reação espermatofórica": breve síntese do conhecimento sobre a estrutura e o funcionamento dos espermatóforos dos cefalópodes (Mollusca: Cephalopoda) [PDF]
Papéis Avulsos de Zoologia, 2011 Cefalópodes coleóides (lulas, sépias e polvos) produzem espermatóforos muito complexos que são transferidos à fêmea durante a cópula por meio do hectocótilo, um apêndice modificado nos machos.

Distribution of pelagic squids Abraliopsis Joubin, 1896 (Enoploteuthidae) and Pterygioteuthis P. Fischer, 1896 (Pyroteuthidae) (Cephalopoda, Decapodiformes, Oegopsida) in the Mexican Pacific [PDF]
ZooKeys, 2015 The oegopsid squids Abraliopsis and Pterygioteuthis are abundant and diverse genera with taxonomic and distributional problems. Identification and distribution of species in the Mexican Pacific has been somewhat controversial.

Natural Habitat and Wild Behaviors of the Dwarf Cuttlefish, <i>Ascarosepion bandense</i>. [PDF]
Ecol EvolGibbons et al. performed a field study to characterize the dwarf cuttlefish—a popular aquarium and research cephalopod—in its natural habitat. They observed dynamic camouflage, social behaviors, and use of an expanded color palette in wild animals compared to laboratory animals.

The functional-morphological adaptive strategy of digestive organs of decapodiform cephalopods
Journal of Veterinary Medical Science, 2015 The digestive organs in decapodiform cephalopod species morphologically vary by individual lifestyle. We examined the following six species of adult decapodiformes cephalopods representing different habitats: Todarodes pacificus, Loligo bleekeri, Loligo ...

Evolutionary history influences the microbiomes of a female symbiotic reproductive organ in cephalopods. [PDF]
Appl Environ MicrobiolMany female squids and cuttlefishes have a symbiotic reproductive organ called the accessory nidamental gland (ANG) that hosts a bacterial consortium involved with egg defense against pathogens and fouling organisms.

Towards an eDNA assay for decapodiform cephalopods [PDF]
ARPHA Conference Abstracts, 2021 Assessing the distribution and diversity of cephalopods using traditional approaches (standard fishing, market collection, and DNA barcoding) is time-consuming. Environmental DNA (eDNA) assays are non-invasive, fast, and can capture the diversity of the species of interest using a specific primer-set.
