Identification of three cephalopods from the Iranian waters of the Gulf of Oman (Continental shelf area) [PDF]

open access: yesIranian Journal of Animal Biosystematics, 2021
This study aimed to find new species of cephalopods in the Iranian waters of the Gulf of Oman. Two species of Oegopsida (Abralia steindachneri Weindl, 1912 and Joubiniteuthis portieri (Joubin, 1916)) and also one species of Sepiida (Sepia omani Adam ...

Future planning Cuttlefish and Octopus

open access: yes, 2023
20 common cuttlefish and 4 common octopuses were tested in a future-planning task. Cuttlefish were tested on their ability to plan for a future need for food instead of following their current need to hide.

The Swimming of Cuttlefish [PDF]

open access: yesNature, 1931
IN NATURE of June 14, 1930, p. 893, F. S. Russell and G. A. Steven publish some observations on the movements of Sepia officinalis, special attention being given to the part played by the siphon. These researches are a confirmation of what was seen by me so long ago as 1912 (Internationale Monatsschrift fur Anatomie und Physiologie, Bd.

Taurine depresses cardiac contractility and enhances systemic heart glucose utilization in the cuttlefish, Sepia officinalis

open access: yes, 2016
Taurine is the most abundant amino acid in the blood of the cuttlefish, Sepia officinalis, where levels can exceed 200 mmol L-1. In mammals, intracellular taurine modulates cardiac Ca2+ handling and carbohydrate metabolism at much lower concentrations ...

Lateralization of eye use in cuttlefish: opposite direction for anti-predatory and predatory behaviors.

open access: yesFrontiers in Physiology, 2016
Vertebrates with laterally placed eyes typically exhibit preferential eye use for ecological activities such as scanning for predators or prey. Processing visual information predominately through the left or right visual field has been associated with ...

Programmable Multi‐Axially Aligned Aerogels via Sequential Freeze‐Casting for Tailored Anisotropy and Tunable Mechanics

open access: yesAdvanced Science, EarlyView.
Conventional single‐gradient freeze‐casting typically produces unidirectional porous architectures with limited transverse connectivity. The Sequential Hybridization by Infiltration and Freeze‐casting Technique (SHIFT) addresses this constraint by integrating secondary aligned structures within a preformed primary scaffold.

Investigating the essential fatty acids in the common cuttlefish Sepia officinalis (Mollusca, Cephalopoda): Molecular cloning and functional characterisation of fatty acyl desaturase and elongase [PDF]

open access: yes, 2016
Some polyunsaturated fatty acids (PUFA) play critical roles in physiology and are essential for normal growth and development of aquatic animals including cephalopods like the common cuttlefish Sepia officinalis.

Altered by Gold: A Comparative Zooarchaeological Analysis of 19th to 20th Century Chinese and British Migrants in Ravenswood, a Northern Queensland Gold Mining Town

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Gold discoveries transformed the 19th century British colony of Queensland, Australia, driving migration, a second wave of pastoral expansion northwards, and an increasingly diverse population. This study presents a comparative and contextual zooarchaeological analysis of British and southern Chinese food waste—globally significant migrant ...

Effects of increased tank bottom areas on cuttlefish (Sepia officinalis, L.) reproduction performance

open access: yes, 2013
Much interest on cuttlefish research during the last years has focused on its introduction as a new species for aquaculture. This is due to this species biological (Barnabe´ 1996) and economical (FAO 2009) aspects which display potential for industrial
