Species Delimitation of Argonauta Paralarvae Reveals an Extensive Morphological Variability in the Northern Humboldt Current System

Diversity
Argonauts or paper nautiluses are pelagic octopod cephalopods with a cosmopolitan distribution in tropical and subtropical waters around the world. Unlike other species of octopus, these are characterized by the fact that the female has a shell that ...

Epibiotic bacterial community composition varies during different developmental stages of Octopus mimus: Study of cultivable representatives and their secondary metabolite production. [PDF]

PLoS ONE
Marine microbial communities colonizing the skin of invertebrates constitute the primary barrier between host and environment, potentially exerting beneficial, neutral, or detrimental effects on host fitness.

Maturation trade-offs in octopus females and their progeny: energy, digestion and defence indicators [PDF]

PeerJ, 2019
Sexual maturation and reproduction influence the status of a number of physiological processes and consequently the ecology and behaviour of cephalopods.

The effectiveness and impact of disinfection with chlorine on embryos and early hatchlings of two Western Pacific octopus species

Journal of the World Aquaculture Society
Replicating maternal care and incubating octopus embryos artificially is advantageous to improve access to embryonic stages, split and share broods, and reduce the required space to culture large quantities of embryos.

Proteogenomic Study of the Effect of an Improved Mixed Diet of Live Preys on the Aquaculture of Octopus vulgaris Paralarvae

Frontiers in Marine Science, 2022
The common octopus is the most demanded cephalopod species for human consumption. Despite important advances realized recently, the main bottleneck for commercial production of the common octopus, Octopus vulgaris, is the mass mortality of paralarvae in ...

Deep octopod habitat in the western North Atlantic characterized by Standard Ecological Classification from videos

Ecosphere, Volume 14, Issue 12, December 2023., 2023
Abstract Habitat characterization is important to assess fully the niches of different organisms. There is a large knowledge gap regarding habitat use by deep‐sea benthic incirrate octopods, partly due to their assumed preference for hard‐to‐sample rocky substrata. This study uses observations from in situ videos recorded by remotely operated vehicles (

Molecular prey identification in wild Octopus vulgaris paralarvae [PDF]

, 2012
The trophic ecology of Octopus vulgaris paralarvae collected in 2008 off the Ría de Vigo, NW Spain (42º12.80’N–9º00.00’W) was approached by both morphological and molecular methods.

You Are What You Eat: A Genomic Analysis of the Gut Microbiome of Captive and Wild Octopus vulgaris Paralarvae and Their Zooplankton Prey

Frontiers in Physiology, 2017
The common octopus (Octopus vulgaris) is an attractive species for aquaculture, however, several challenges inhibit sustainable commercial production. Little is known about the early paralarval stages in the wild, including diet and intestinal microbiota,
