Diet Composition and Variability of Wild Octopus vulgaris and Alloteuthis media (Cephalopoda) Paralarvae: a Metagenomic Approach

open access: yesFrontiers in Physiology, 2017
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

Vertical distribution and abundance of juvenile cephalopods in Aegean Sea

open access: yesScientia Marina, 2003
This study was carried out in northern (Saros Bay) and southern (Gökova Bay) parts of the Aegean Sea. In pelagic samplings, Hamburg Plankton Net (HPN) was used. Samplings were done out at four different periods of a 24 hour day; sunrise, noon, sunset and

Life histories of Antarctic incirrate octopods (Cephalopoda: Octopoda)

open access: yesPLoS ONE, 2019
As a general trend in the life history of marine organisms, species inhabiting cold waters have reduced growth rates and increased lifespans. Studies based on egg sizes and brooding times of deep-sea and polar octopods support this hypothesis, but ...

Clues of ancient incomplete lineage sorting during bivalve evolution undermine support for Heterodonta

open access: yesCladistics, EarlyView.
Abstract A long‐standing challenge in phylogenomics has been the resolution of relationships originated from ancient radiations. In these cases, phenomena such as incomplete lineage sorting can increase the support for conflicting resolutions. Most of the diversity in the Class Bivalvia originated during an Ordovician radiation; indeed, several deep ...
