Trophic ecology of Octopus vulgaris paralarvae along the Iberian Canary current eastern boundary upwelling system [PDF]

Scientific Reports, 2023
Our knowledge of the diet of wild octopus paralarvae, Octopus vulgaris, is restricted to the first 2 weeks of its planktonic phase when they are selective hunters found near the coastline.

First Observation of Embryonic Development and Paralarvae of Amphioctopus kagoshimensis [PDF]

Animals
To evaluate the aquaculture potential of Amphioctopus kagoshimensis, we investigated the reproductive biology, embryonic development, and early paralarval morphology of Amphioctopus kagoshimensis under controlled laboratory conditions.

Admixture and Selection Driven by El Niño-Southern Oscillation Events Shape the Genetic Structure of <i>Octopus mimus</i>-<i>O. hubbsorum</i> Complex Across the Humboldt and South Equatorial Current Transition Zone. [PDF]

Ecol Evol
Whole‐genome sequencing of the Octopus mimus–O. hubbsorum complex in the eastern Pacific identified two main genetic clades—northern warm‐water and southern cold‐water lineages—with a broad admixture zone during ENSO years where admixed individuals reflect both their genomic makeup and local environments.

Characterization of cannibalism in early paralarvae of Patagonian red octopus, Enteroctopus megalocyathus (Gould, 1852), grown in a controlled environment

Journal of the World Aquaculture Society, 2021
In the experimental mariculture of Patagonian red octopus, Enteroctopus megalocyathus, paralarvae rearing showed the highest mortalities. Part of this mortality has been attributed to cannibalism, so we studied the joint effect of paralarvae density and ...

New insights into the feeding behaviour of the Japanese squid Todarodes pacificus paralarvae, and a combined analysis of metagenome and amino acid isotope ratios. [PDF]

PLoS ONE
The Japanese flying squid Todarodes pacificus (Ommastrephidae) is a commercially and ecologically important species; however, there remains much room for investigation in its early life phase, especially its diet in wild environments.

Squids use multiple escape jet patterns throughout ontogeny [PDF]

Biology Open, 2020
Throughout their lives, squids are both predators and prey for a multitude of animals, many of which are at the top of ocean food webs, making them an integral component of the trophic structure of marine ecosystems.

The Effect of Prey Size and Prey Density on Paralarval Feeding Success of the Common Sydney Octopus, Octopus tetricus

Aquaculture, Fish and Fisheries
Global demand for octopus seafood has been increasing over the past 30 years. This demand is projected to increase further as coastal communities and seafood consumers seek alternative sources of protein as finfish stocks decline.

Genomic Divergence Between <i>Octopus vulgaris</i> and Its Undescribed Sister Species From the South Atlantic and Indian Ocean. [PDF]

Ecol Evol
Octopus vulgaris Type III — an undescribed Southern Hemisphere lineage occurring along the South African coast and Amsterdam Island — is genomically distinct from O. vulgaris sensu stricto and O. sinensis, as inferred from phylogenetic analyses of 338 nuclear loci and complete mitochondrial genomes, supporting the need for taxonomic re‐evaluation of ...

Development of Swimming Abilities in Squid Paralarvae: Behavioral and Ecological Implications for Dispersal [PDF]

Frontiers in Physiology, 2018
This study investigates the development of swimming abilities and its relationship with morphology, growth, and nourishment of reared Doryteuthis opalescens paralarvae from hatching to 60 days of age.

The Tentacular Strike Behavior in Squid: Functional Interdependency of Morphology and Predatory Behaviors During Ontogeny [PDF]

Frontiers in Physiology, 2019
This study examines the relationship between morphology and predatory behaviors to evaluate the ontogeny of the specialized tentacular strike (TS) in Doryteuthis opalescens squid reared under laboratory conditions [hatching to 80 day-old; 2–16 mm mantle ...
