Young Sepia officinalis (0-5 months) were studied in the laboratory and sea, their appearance behaviour compared with that of adult animals. Cuttlefish lay large eggs hatchlings are miniature replicas adults. From moment hatching they show body patterns as complex those adults far more elaborate than shown by most juvenile cephalopods. There 13 patterns: 6 these ‘chronic’ (lasting for minutes or hours) 7 ‘acute’ seconds minutes). The built up from no fewer 34 chromatic, textural, 8 postural...
Technologies that use stretchable materials are increasingly important, yet we unable to control how they stretch with much more sophistication than inflating balloons. Nature, however, demonstrates remarkable of surfaces; for example, cephalopods can project hierarchical structures from their skin in milliseconds a wide range textural camouflage. Inspired by cephalopod muscular morphology, developed synthetic tissue groupings allowed programmable transformation two-dimensional (2D) surfaces...
Significance Artificial systems that replicate functional attributes of the skins cephalopods could offer capabilities in visual appearance modulation with potential utility consumer, industrial, and military applications. Here we demonstrate a complete set materials, components, fabrication approaches, integration schemes, bioinspired designs, coordinated operational modes for adaptive optoelectronic camouflage sheets. These devices are capable producing black-and-white patterns...
In this paper, we describe our recent results in the development of a new class soft, continuous backbone ("continuum") robot manipulators. Our work is strongly motivated by dexterous appendages found cephalopods, particularly arms and suckers octopus, tentacles squid. ongoing investigation these animals reveals interesting unexpected functional aspects their structure behavior. The arrangement dynamic operation muscles connective tissue observed variety octopus species motivate underlying...
Although hearing has been described for many underwater species, there is much debate regarding if and how cephalopods detect sound. Here we quantify the acoustic sensitivity of longfin squid (Loligo pealeii) using near-field shaker-generated acceleration stimuli. Sound field pressure particle motion components were measured from 30 to 10,000 Hz stimuli 20 1000 Hz. Responses determined auditory evoked potentials (AEPs) with electrodes placed near statocysts. Evoked generated by both...
Abstract Chromatophore organs in cephalopod skin are known to produce ultra-fast changes appearance for camouflage and communication. Light-scattering pigment granules within chromatocytes have been presumed be the sole source of coloration these complex organs. We report discovery structural emanating precise register with expanded pigmented chromatocytes. Concurrently, using an annotated squid chromatophore proteome together microscopy, we identify a likely biochemical component this...
Bodily injury in mammals often produces persistent pain that is driven at least part by long-lasting sensitization and spontaneous activity (SA) peripheral branches of primary nociceptors near sites injury. While have been described lower vertebrates invertebrates, outside there limited evidence for afferent neurons, are no reports SA being induced afferents noxious stimulation. Cephalopod molluscs the most neurally behaviorally complex with brains rivaling those some size complexity. This...
Commercial off-the-shelf digital cameras are inexpensive and easy-to-use instruments that can be used for quantitative scientific data acquisition if images captured in raw format processed so they maintain a linear relationship with scene radiance. Here we describe the image-processing steps required consistent color cameras. In addition, present method scene-specific calibration increases accuracy of capture when contains colors not well represented gamut standard color-calibration target....
Abstract In-situ visual observations of marine organisms is crucial to developing behavioural understandings and their relations surrounding ecosystem. Typically, these are collected via divers, tags, remotely-operated or human-piloted vehicles. Recently, however, autonomous underwater vehicles equipped with cameras embedded computers GPU capabilities being developed for a variety applications, in particular, can be used supplement existing data collection mechanisms where human operation...
We tested the hypothesis that soft-bodied octopuses, which spend most of their lives in dens, remain highly cryptic as primary defence against predation while they forage. videotaped foraging octopuses on two widely dispersed Pacific coral reefs and developed a rigorous method to analyse degree crypsis from videotapes. Five ranks were assigned (two of' cryptic', one 'moderately 'conspicuous') assess each octopus's body pattern match its background, using criteria brightness, colour, shape...
Hundreds of Sepia officinalis were hatched and cultured through the life cycle in each 13 populations. Two genetic lines maintained: one for an unprecedented seven generations another presently its fourth. All generations—save one—produced animals excess 1·0 kg body weight. Seven eight with adequate data records had mean weights 1–2 kg, largest cuttlefish reared a male 2·6 female 2·9 kg. Fecundity levels high, but there was trend towards decreased fertility later generations, fertilization...
