Natural Habitat and Wild Behaviors of the Dwarf Cuttlefish, <i>Ascarosepion bandense</i>. [PDF]

Ecol Evol
Gibbons 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 complete mitochondrial genomes of two octopods Cistopus chinensis and Cistopus taiwanicus: revealing the phylogenetic position of the genus Cistopus within the order Octopoda. [PDF]

PLoS ONE, 2013
In the present study, we determined the complete mitochondrial DNA (mtDNA) sequences of two species of Cistopus, namely C. chinensis and C. taiwanicus, and conducted a comparative mt genome analysis across the class Cephalopoda.

Every hooked beak is maintained by a prey: Ecological signal in cephalopod beak shape

Functional Ecology, Volume 36, Issue 8, Page 2015-2028, August 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Beaks are among the few hard parts of coleoid cephalopods and are informative for species identification. Although mandible shape has been shown to be adaptive in many vertebrate taxa, it has been suggested that the shape of coleoid beaks does not bear any ecological ...

Systematics and Phylogenetic Relationships of New Zealand Benthic Octopuses (Cephalopoda: Octopodoidea)

Frontiers in Marine Science, 2020
The systematics of the New Zealand octopods have only been reviewed twice in the last 100 years. In these revisions many species have been provisionally classified in the genus Octopus.

O enigma da "reação espermatofórica": breve síntese do conhecimento sobre a estrutura e o funcionamento dos espermatóforos dos cefalópodes (Mollusca: Cephalopoda)

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.

Coupled Genomic Evolutionary Histories as Signatures of Organismal Innovations in Cephalopods

BioEssays, Volume 41, Issue 12, December 2019., 2019
How genomic innovation translates into organismal organization remains largely unanswered. Cephalopods provide a unique model system to investigate how organismal novelties evolve. Here, it is discussed how co‐evolutionary signatures among various genomic characters have contributed to cephalopod organismal novelties and can be used to dissect their ...

DNA metabarcoding for diet analysis and biodiversity: A case study using the endangered Australian sea lion (Neophoca cinerea)

Ecology and Evolution, Volume 7, Issue 14, Page 5435-5453, July 2017., 2017
The Australian sea lion is an endangered apex predator which is endemic to Western Australia. We collected and extracted the DNA from 36 scats taken from five known sea lion haul out locations around the southeast coast of Western Australia. Several assays were used to target barcode sequences to both identify the diet of the sea lions and gain insight
