Tublitz SUMMARY The goal of this work was to identify some of the principles underlying chromatophore growth and development in the European cuttlefish, Sepia officinalis . One...

... the camouflage patterns of Sepia officinalis during the transition from daytime to night-time using a natural daylight cycle and (2) tested whether cuttlefish on a particular artificial substrate change their camouflage body patterns when the substrate is changed under dim light (down to starlight, 0.003 lux...

... disruptive patterns is dependent not only on object size but also on their body size. Here, we tested whether cuttlefish ( Sepia officinalis ) are able to match their disruptive body patterning with increasing size of background objects as they grow from hatchling to adult size (0.7 to 19.6 cm mantle length...

... cuttlefish( Sepia officinalis L.). The anterior vena cava contracted at the same rate as the mantle, but it often expanded during mantle contraction. Furthermore, the anterior vena cava contracted peristaltically in vivo , suggesting that it actively aids venous return. The lateral venae cavae and efferent...

...R. H. Douglas; R. Williamson; H.-J. Wagner SUMMARY This paper provides the first detailed description of the time courses of light-evoked pupillary constriction for two species of cephalopods, Sepia officinalis (a cuttlefish) and Eledone cirrhosa (an octopus). The responses are much faster than...

... that are directly innervated by central motoneurons. The present study focuses on innervation patterns and location of chromatophore motoneurons in the European cuttlefish Sepia officinalis , specifically those motoneurons that control chromatophores of the fin. The fin is known to be innervated by the large...

Sweedler; Lingjun Li; Philip Floyd; William Gilly ABSTRACT A matrix-assisted laser desorption/ionization (MALDI) mass spectrometric (MS) survey of the major peptides in the stellar, fin and pallial nerves and the posterior chromatophore lobe of the cephalopods Sepia officinalis, Loligo...

...N. A. Curtin; R. C. Woledge; Q. Bone ABSTRACT The passive elastic properties of the mantle of the cuttlefish Sepia officinalis have been characterized in experiments on intact mantle and on pieces cut from the mantle. The mantle was found to be very compliant over a wide range of circumferential...

...Frank Schaeffel; Christopher J. Murphy; Howard C. Howland ABSTRACT We have studied natural accommodation in the eye of six specimens of cuttlefish ( Sepia officinalis ) as they were fed with fish and shrimp. Using infrared photoretinoscopy, we observed (1) that the resting refractive state...

...B. Versen; S. Gokorsch; A. Fiedler; R.

... of the cuttlefish Sepia officinalis (L.) (Sub-class Coleoidea, Order Sepiida) is presented, together with an analysis of the structure of the gene. A proline-rich C terminus is present; this structure is characteristic of cephalopod rhodopsins. In common with all invertebrate opsins studied so far, the equivalent...

Thin slices of muscle were used for twitch...

Brief tetani or twitch stimuli were used as this pattern is likely...

...Poh Kheng Loi; Nathan Tublitz ABSTRACT The display of complex color patterns of the cuttlefish Sepia officinalis is under the regulation of the FMRFamide-related peptide (FaRP) family, but their exact identities are unknown. We report the isolation and characterization of a full-length FaRP cDNA...

.... This sensitivity arises from the orthogonal orientation of neighboring photoreceptors. Electron microscopical examination of the retina of the cuttlefish Sepia officinalis L. revealed the same orthogonal structure, suggesting that cuttlefish are also sensitive to linearly polarized light. Viewing cuttlefish...

... in the European cuttlefish Sepia officinalis are also regulated by the FMRFamide family of neuropeptides. Using an in vitro chromatophore bioassay, it has been determined that several FMRFamide-related peptides (FaRPs) are potent excitors of the chromatophore muscles, causing chromatophore expansion...
