Coupled Genomic Evolutionary Histories as Signatures of Organismal Innovations in Cephalopods [PDF]
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 ...

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.

Genome skimming elucidates the evolutionary history of Octopoda [PDF]
, 2023 Phylogenies for Octopoda have, until now, been based on morphological characters or a few genes. Here we provide the complete mitogenomes and the nuclear 18S and 28S ribosomal genes of twenty Octopoda specimens, comprising 18 species of Cirrata and ...

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 ...

High-Density Genetic Linkage Map of the Southern Blue-ringed Octopus (Octopodidae: Hapalochlaena maculosa) [PDF]
, 2022 Genetic linkage maps provide a useful resource for non-model genomes and can aid in genome reassembly to form more contiguous pseudo-chromosomes. We present the first linkage map of any cephalopod, H. maculosa, composed of 47 linkage groups (LG). A total

A phylogeny of fossil and living neocoleoid cephalopods [PDF]
, 2015 Coleoid cephalopod phylogeny is well studied via both molecular and morphological data, yet although some agreement has been reached (e.g. that extant Decapodiformes and Octopoda are monophyletic) many details remain poorly resolved. Fossil coleoids, for

Larval ascaridoid nematodes in horned and musky octopus (Eledone cirrhosa and E. moschata) and longfin inshore squid (Doryteuthis pealeii): Safety and quality implications for cephalopod products sold as fresh on the Italian market [PDF]
, 2020 The aim of this study was to evaluate the occurrence, infection level and distribution of ascaridoid larvae in cephalopod products sold in Italy. Data on the species most commonly commercialized as whole and fresh on the Italian market were collected ...

Actin Gene Family Evolution and the Phylogeny of Coleoid Cephalopods (Mollusca: Cephalopoda) [PDF]
, 2000 Phylogenetic analysis conducted on a 784-bp fragment of 82 actin gene sequences of 44 coleoid cephalopod taxa, along with results obtained from genomic Southern blot analysis, confirmed the presence of at least three distinct actin loci in coleoids ...

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
