Training Transhumanism : I want to become a cephalopod
… technological change, based on the model of the cephalopod. We focus on three main traits: (1) Embodied and tactile awareness and cognition; (2) The resiliency of camouflage, defined as a hyper-awareness of one's local environment and the flexibility to respond swiftly by morphing one's perceived …

Kinematics and Hydrodynamics of Cephalopod Turning Performance in Routine Swimming and Predatory Attacks
… quantitative turning performance study of cephalopods to date and demonstrates that the unique body architecture of these taxa provides exceptional advantages for maneuvering in the marine environment.</p>

Exploring the Cephalopod Brain: Towards Mapping the First Whole Brain Connectome and Whole Animal Projectome of a Pygmy Squid
Cephalopods have arguably the most complex central nervous system of all studied invertebrates. They possess large, highly centralised brains for processing sensory information, higher cognitive functioning, motor control, and feeding. Cephalopods are known for their ability to solve problems in …

Hydrodynamic and structural constraints on ammonoid shell shape
… been thought that the the shells of chambered cephalopods served as buoyancy compensation devices. However, it was not until the 1960's that the internal pressure of the shell was demonstrated to be less than one atmosphere, and that the shell structure supports hydrostatic load. It is …

Vision and Bioluminescence in Cephalopods
… and bioluminescence through an examination of cephalopods, a highly visual group that exhibits a broad diversity of eye adaptations and multiple evolutions of bioluminescence. My research investigates (1) vision and behavior in a deep-sea squid with dimorphic eyes, (2) depth-dependent patterns …

The Response of a Predatory Fish, Ophiodon elongatus, to a Marine Protected Area: Variation in Diet, Catch Rates, and Size Composition
… the REF site. Lingcod in the REF consumed more cephalopod prey items than Lingcod in the MPA. I analyzed the four most common prey items (rockfish, anchovies, flatfish, and octopus) for nutritional content. My data suggest that Lingcod increased in size and abundance in a no-take MPA because …

Protozoi ed Elminti parassiti dei molluschi cefalopodi delle acque circostanti la Sardegna. Morfologia, sistematica, epidemiologia, possibile utilizzo dei parassiti come indicatori bioecologici
Cephalopods are marine organisms which play a crucial role in the food webs of all the world oceans both as preys and predators. They are also actively exploited in many areas, with a rapid increase of their commercial value in the last decades. Despite this, the knowledge on the role of …

Dispersion of seabirds at sea in the Southern Ocean
… (penguins excluded). Birds eating plankton and cephalopods are the most abundant; few birds eat fish. Plankton- and cephalopod-eaters occur most abundantly in the south and north of the study area, respectively. An association between their distribution and the availability of their principal …

Designing a microhydraulically-driven mini-robotic squid
… driving component. The system was inspired by cephalopod paralarvae, which predominantly rely on jet propulsion in their early stages of development. The squid robot can produce thrust by diaphragm pump-like operation, in either single-acting or double-acting modes. Since the actuator is a …

Programmable adhesion in dry and wet environments through geometric design
… art-inspiration (Kirigami) and bio-inspiration (Cephalopod). Chapter 2 explores the mechanical aspects of adhesive peeling. We compare experimental data with theoretical models to discuss the effect of energy dissipation, particularly through the plastic work of the adherend. Chapter 3 introduces …

Assessing anthropogenic noise impacts and relevant soundscape cues for marine invertebrates: leveraging squid and coral reefs as model systems
Sound is utilized by marine animal taxa for many ecologically important functions, and these taxa are vulnerable to adverse effects of anthropogenic noise on hearing and behavior. However, little is known about marine invertebrates’ responses to anthropogenic noise, and the ambient environmental …

MICROMORPHOLOGY AND GENE EXPRESSION IN MUSCLE AND SHELL DEVELOPMENT OF THE MOLLUSCA
… which is also found in the basal gastropod and cephalopod bauplan but not in the Bivalvia, suggests a clade comprising the Scaphopoda and Gastropoda + Cephalopoda. This is strengthened by expression data of the homeobox gene engrailed, which plays a significant role in molluscan shell formation. …

Variability in the diet of cape fur seals and their interaction with fisheries off the South African coast, 2010-2019
… in the Cape fur seal diet. Fish otoliths, cephalopod beaks and seabird feathers were used to identify prey to the lowest taxonomic level possible, and the mass and length of fish prey were estimated from otolith lengths using regression equations. Fifty-three prey taxa (43 fish, 6 …

Dynamic lighting and its impact on the behaviour of marine invertebrates
All animals face the fundamental problem of extracting information from noisy environments. To mitigate or exploit the impacts that environmental noise may have on their sensory systems, many animals adapt their behaviour when exposed to environmental stimuli that interfere with their ability to …
