چکیده

This study examines the ability of Octopus vulgaris to prey on bivalve molluscs showing that octopuses exhibited the same behavioural pattern irrespective of the prey species. When the initial pulling method did not result efficient octopuses skipped to drilling accompanied by an increase in the handling time. A complete behavioural repertoire of O. vulgaris in handling bivalve preys is also given.

The Sydney octopus (Octopus tetricus) occurs in unusual numbers on a shell bed of its prey remains that have accumulated as an extended midden where additional octopuses excavate dens. Here, O tetricus are ecosystem engineers, organisms that modulate availability of resources to other species and to their own species by causing physical state changes in materials. A community of invertebrate gr...

This work reports a genetic data of Octopus vulgaris, marine species of high commercial value, from nineteen localities of Atlantic, Mediterranean and the Adriatic regions. We used mitochondrial DNA cytochrome c oxidase subunit I (COI) gene to investigate the genetic structure of common octopus. Our results indicated a significant genetic structuring in the study area (Phi = 0.136, P <0.001) an...

During the present study, we aimed at providing a first look at the elemental composition of the early stages of cephalopods as an approach to their elemental requirements in culture. Essential and non-essential elemental profiles of the European cuttlefish Sepia officinalis, the European squid Loligo vulgaris and the common octopus Octopus vulgaris laboratory hatchlings and wild juveniles were...

The high mortality of cephalopod early stages is the main bottleneck to grow them from paralarvae to adults in culture conditions, probably because the inadequacy of the diet that results in malnutrition. Since visual analysis of digestive tract contents of paralarvae provides little evidence of diet composition, the use of molecular tools, particularly next generation sequencing (NGS) platform...

The genetic variability of the COI gene was studied in the common octopus, Octopus vulgaris Cuvier, 1797. A total of 222 individuals from 7 sampling sites were analysed with the aim of elucidating patterns of genetic variation along the coasts of Sardinia (Western Mediterranean). A total of 17 different haplotypes were identified with four principal haplotypes recorded in all locations. The pai...
