Cuttlebone, the sophisticated buoyancy device of cuttlefish, is made of extensive superposed chambers that have a complex internal arrangement of calcified pillars and organic membranes. It has not been clear how this structure is assembled. We find that the membranes result from a myriad of minor membranes initially filling the whole chamber, made of nanofibres evenly oriented within each memb...

ABSTRACT To conceal themselves on the seafloor, European cuttlefish, Sepia officinalis, express a large repertoire of body patterns. Scenes with 3D relief are especially challenging because it is not possible either to directly recover visual depth from 2D retinal image or for cuttlefish alter its shape resemble nearby objects. Here, we characterised camouflage responses relief, and cast shadow...

Cephalopods, such as octopus and squid, can change their coloration in an instant, and even produce moving patterns on their skin. A new study describes these wavelike patterns in a colourful tropical cuttlefish, providing insights into the neural mechanisms that generate them.

This article comprises an up-dated review of the processes influencing the distribution and abundance of common cuttlefish Sepia officinalis, the interactions between the species and the main parameters of the environment in which it lives and its trophic, demographic and behavioural ecology.

The functional relevance of oxygen transport by hemocyanin of the Antarctic octopod Megaleledone senoi and of the eurythermal cuttlefish Sepia officinalis was analyzed by continuous and simultaneous recordings of changes in pH and hemocyanin oxygen saturation in whole blood at various temperatures. These data were compared to literature data on other temperate and cold-water cephalopods (octopo...

We experienced five cases of Salmonella oranienburg infection in children living in Saitama prefecture. Thereafter the number of patients with S. oranienburg infection increased not only in Saitama (55 cases) but also in other parts of Japan in 1999 (1505 cases) in 1999. The source of S. oranienburg infection was identified as a snack made from semi-dry cuttlefish.

Population substructure of the cuttlefish Sepia officinalis (Mollusca: Cephalopoda), as investigated by genetic variation of microsatellite loci, has been reported to be significantly extensive around the Iberian Peninsula with F(ST)=0.061 [Pérez-Losada, M., Guerra, A., Carvalho, G.R., Sanjuan, A., Shaw, P.W., 2002. Extensive population subdivision of the cuttlefish Sepia officinalis (Mollusca:...

Due to the current energy crises, search for thermal management systems based on insulating porous materials has drawn a significant deal of attention. Herein, we demonstrated insulation and capabilities cuttlefish bone mimetic aerogels with hierarchically organized structures directly fabricated from surface-modified self-assembled silk fibroin (SF) biopolymer extracted Bombyx mori silkworm co...
