Assessing the lifespans of coldwater octopods (Cephalopoda: Octopodiformes) [PDF]

open access: yes, 2019
This thesis dissertation investigates longevity of deep-sea and Antarctic octopodiform species using life history traits and the quantification of growth increments in the octopods’ beaks (chitinous jaws). The first chapter investigates how life history traits including embryonic development, hatchling size, size- and age-at-maturity are correlated ...

Revisiting the identification of Syllipsimopodi bideni and timing of the decabrachian-octobrachian divergence. [PDF]

open access: yesNat Commun, 2023
Recently, on the basis of a single specimen (ROMIP 64897) from the Royal Ontario Museum (Canada), Whalen and Landman1 described the new coleoid taxon with a fairly completely preserved frontal part as Syllipsimopodi bideni.

Evolution of the gills in the octopodiformes [PDF]

open access: yes, 2002
The gills of cirrate octopods are known to be unusual with terms 'half orange' and 'sepioid' commonly used to describe them. The structure and relationships of these gills to other cephalopod gills have not been adequately investigated.

Evolutionary progression in cephalopods using molecular techniques and new approaches to morphology

open access: yes, 2021
Cephalopods evolved during the Cambrian and were once the dominant lifeforms in the world’s oceans. Several groups of the 800 living cephalopod species have diversified due to their rapid response to drivers of evolution and different adaption ...

A phylogeny of fossil and living neocoleoid cephalopods [PDF]

open access: yes, 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

What can the mitochondrial genome reveal about higher-level phylogeny of the molluscan class Cephalopoda?

open access: yes, 2011
We present the first analysis of cephalopod mitochondrial gene order and construct phylogenies based on gene order using Bayesian, distance, and parsimony analysis methods.

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

open access: yesFisheries Management and Ecology, Volume 33, Issue 3, Page 612-629, June 2026.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting.
