Diversity of apostome ciliates, Chromidina spp. (Oligohymenophorea, Opalinopsidae), parasites of cephalopods of the Mediterranean Sea

open access: yesParasite, 2016
Chromidina spp. are enigmatic apostome ciliates (Oligohymenophorea, Opalinopsidae) that parasitise the renal and pancreatic appendages of cephalopods. Only four species have been described, among which only three have been formally named. No DNA sequence

The Cuttlebone Blueprint for Multifunctional Metamaterials: Design Taxonomy, Functional Decoupling, and Future Horizons

open access: yesAdvanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
Cuttlebone‐inspired metamaterials exploit a septum‐wall architecture to achieve excellent mechanical and functional properties. This review classifies existing designs into direct biomimetic, honeycomb‐type, and strut‐type architectures, summarizes governing design principles, and presents a decoupled design framework for interpreting multiphysical ...

The Possible Protective Role of Powder Cuttlefish Bone, Crabshell and Eggshell on Osteoporotic Rats [PDF]

open access: yesJournal of Food and Dairy Sciences, 2018
Bone mass declines alongside maturing, particularly for ladies after menopause as a result of diminishing estrogen emission together with low calcium consumption.

Sperm Transfer Under Behavioral and Morphological Constraints in the Orb‐Web Spider Genus Argiope

open access: yesIntegrative Zoology, Volume 21, Issue 3, Page 485-498, May 2026.
The polygamous mating system of the orb‐web spider genus Argiope provides a model to study the evolution of sperm transfer under morphological and behavioral constraints. This helps us to understand how male and female behavioral and morphological reproductive traits influence sperm transfer.

Shoaling behaviour in the European cuttlefishSepia officinalis

open access: yesEthology, 2021
AbstractGroup living is a common behavioural feature in many different animal species. It offers a multitude of fitness benefits, such as increased opportunities to find resources, improved predator vigilance and potentially even social learning. In cephalopods, social grouping behaviour has mainly been reported for squid species, with up to several ...

Siphonal zone structure in the cuttlebone of Sepia officinalis

open access: yesSwiss Journal of Palaeontology, 2015
The evolutionary process through which the siphonal zone of the cuttlebone of Sepia replaced the tubular siphuncle seen in other shelled cephalopods is poorly understood. Recently, porous connecting stripes, interpreted as homologous to connecting rings of tubular siphuncles, were revealed in Sepia (Acanthosepion) cf. savignyi (Geobios, 45:13–17, 2012).

From commons to commoning as resistance efforts to blue injustice: A sociohistorical and ethnographical approach

open access: yesPeople and Nature, Volume 8, Issue 4, Page 835-853, April 2026.
Abstract Over the last 20 years, collaborative efforts have emerged with the intention of going beyond the pure capitalist economy, seeking to generate transformative community‐based changes that guarantee blue equity, fair distribution and well‐being.

Classification of European Illex coindetii and Loligo forbesii Squid Stocks by Trace Element Analysis of Statoliths

open access: yesFisheries Management and Ecology, Volume 33, Issue 2, Page 181-200, April 2026.
ABSTRACT We investigated whether statolith microchemistry analysis could classify ommastrephid and loliginid squid species into fishery stocks. Statolith nucleus (early life stage) and edge (life stage at time before catch) of Illex coindetii (Verany, 1839) and Loligo forbesii (Steenstrup, 1856) from various areas of the North East Atlantic Ocean and ...

Ecosystem Impacts of the Landing Obligation for Unwanted Catch in Thermaikos Gulf (Greece)

open access: yesFisheries Management and Ecology, Volume 33, Issue 2, Page 246-259, April 2026.
ABSTRACT Discards by marine commercial fisheries have been an issue of major concern to the scientific community in recent years. We modeled the ecological and trophic consequences of a mandatory landing obligation (LO) regulated by the reformed Common Fisheries Policy [Regulation (EU) 1380/2013] on the Thermaikos Gulf ecosystem (northwestern Aegean ...

CHEMICAL BIO-COMPOUNDS AND FUNCTIONAL PROPERTIES OF RAW AND PROCESSED CUTTLEFISH, SEPIA OFFICINALIS (MOLLUSCA: CEPHALOPODA)

open access: yesFood and Environment Safety, 2018
Cuttlefish is one of the most economically important cephalopods with rich taste and few inedible parts. The study was aimed at evaluating the nutrient, non-nutrients, free fatty acid and cholesterol compositions and functional properties of raw and ...
