Cephalopod Cognition
Focusing on comparative cognition in cephalopods, this book illuminates the wide range of mental function in this often overlooked group.
Cephalopod Behaviour
A fully updated overview of the causation, function, development and evolution of cephalopod behaviour, richly illustrated in full colour.
CephsInAction: Towards Future Challenges for Cephalopod Science
The last five years have been extremely challenging, but also very innovative for cephalopod science, and the outstanding tradition of biological contribution with cephalopod molluscs as key players in science and human activities and interests has continued. This Research Topic is one of several dedicated to cephalopod molluscs (e.g., Hanke and Osorio, 2018; Ponte et al., 2018) hosted by Frontiers over the last few years, not to mention other papers published separately. Highlighting of cephalopod science is important because it has much to offer not only the life science community, but also more broadly the public perception of science and its understanding and relationship with scientific...
Invertebrate Learning and Memory
Understanding how memories are induced and maintained is one of the major outstanding questions in modern neuroscience. This is difficult to address in the mammalian brain due to its enormous complexity, and invertebrates offer major advantages for learning and memory studies because of their relative simplicity. Many important discoveries made in invertebrates have been found to be generally applicable to higher organisms, and the overarching theme of the proposed will be to integrate information from different levels of neural organization to help generate a complete account of learning and memory. Edited by two leaders in the field, Invertebrate Learning and Memory will offer a current an...
Ingenious
As humans evolved, we developed technologies to modify our environment, yet these innovations are increasingly affecting our behavior, biology, and society. Now we must figure out how to function in the world we’ve created. Over thousands of years, humans have invented ingenious ways to gain mastery over our environment. The ability to communicate, accumulate knowledge collectively, and build on previous innovations has enabled us to change nature. Innovation has allowed us to thrive. The trouble with innovation is that we can seldom go back and undo it. We invent, embrace, and exploit new technologies to modify our environment. Then we modify those technologies to cope with the resulting ...
Invertebrate Learning and Memory
This chapter summarizes the literature on the anatomical and functional organization of the cuttlefish brain, with a focus on the structures involved in learning and memory processes (namely the vertical lobe system and optic lobes). Also, different learning paradigms that are commonly used in Sepia officinalis are described with, when possible, their neural correlates. Recent work on the early development of brain and memory is also reviewed. Some research directions to follow in the field of neurobiology of learning and memory in cuttlefish are suggested to better understand the extraordinary behavioral plasticity of these sophisticated invertebrates.
Squid
In myths and legends, squids are portrayed as fearsome sea-monsters, lurking in the watery deeps waiting to devour humans. Even as modern science has tried to turn those monsters of the deep into unremarkable calamari, squids continue to dominate the nightmares of the Western imagination. Taking inspiration from early weird fiction writer H. P. Lovecraft, modern writers such as Jeff VanderMeer depict squids as the absolute Other of human civilization, while non-Western poets such as Daren Kamali depict squids as anything but threats. In Squid, Martin Wallen traces the many different ways humans have thought about and pictured this predatory mollusk: as guardians, harbingers of environmental collapse, or an untapped resource to be exploited. No matter how we have perceived them, squids have always gazed back at us, unblinking, from the dark.

Vision in Cephalopods
Cephalopods usually have large and mobile eyes with which they constantly scan their environment. The eyes of cephalopods are single-chamber eyes which show resemblance to vertebrate eyes. However there are marked differences such as the cephalopod eye having an everted retina instead of an inverted retina found in vertebrates. Their visual system allows the cephalopods, depending on species, to discriminate objects on the basis of their shapes or sizes, images from mirror images or to learn from the observation of others. The cephalopod visual system is also polarization sensitive and controls camouflage, an extraordinary ability almost exclusive to all cephalopods; they are capable of rapi...
