Cephalopods are the most intelligent, most mobile, and the largest of all molluscs squid, octopuses, cuttlefish, the chambered nautilus, and their relatives display remarkable diversity in size and lifestyle with adaptations for predation, locomotion, disguise, and communication. Herein, we provide an overview of selected literature examples that have used cephalopods as models for the development of novel adaptive materials, devices, and systems we in turn highlight some significant remaining challenges and potential future directions for such studies.

Cephalopods have been among the dominant large predators in the ocean at various times in geological history two groups of cephalopods exist today: the nautiloidea with a few species of the pearly nautilus, and the coleoidea, containing the squids, cuttlefishes, octopods and vampire squids, which is represented by about 700 species. Cephalopods are widely regarded as the most intelligent of the invertebrates and have well developed senses and large brains larger than the brains of gastropods or bivalves. Vertebrates of bc overview it was years later that the affinities between cephalopods and the myriad of hard shelled animals such as clams and snails was. There are over 800 extant species of cephalopod, although new species continue to be described an estimated 11,000 extinct taxa have been described, although the soft-bodied nature of cephalopods means they are not easily fossilised.
Cephalopoda the aim is to create an overview of which groups are proving the most nautilus was used as the outgroup for the analysis of all cephalopods. Cephalopods (octopus, squid, cuttlefish) are among the most intelligent invertebrates, with highly developed nervous systems which provide excellent model systems for investigating basic questions in neuroscience.

Overview the molluscan class cephalopoda--squids and octopuses being the most familiar examples--includes a remarkable diversity of tentacled marine predators that use a jet propulsion system to move through the water, in some cases very quickly. In this primer, i provide an overview of recent work on the mechanisms and principles of rapid adaptive camouflage of cephalopods — octopus, cuttlefish and squids these strange but capable marine invertebrates can camouflage themselves against almost any background, a feat well appreciated by aristotle, and one never mastered by any land animal.
Cephalopoids were species which resembled or were related to cephalopods (a group of highly intelligent invertebrate molluscs, usually oxygen-breathing, often with color-changing abilities, often with large eyes capable of low-light vision, often amphibious, often with an internal or external. Cephalopods are ancient group of highly advanced predatory creatures that make-up an entirely marine group within the phylum mollusca and are recorded as far back as the late cambrian (albertin, et al, 2012. Overestimation of cephalopod frequency in predator diets could arise because cephalopod remains persist longer than those of other prey another source of uncertainty is the scaling up of limited predator and fishery data to ocean basin scales and the low carbon content (watery tissues) of many mesopelagic cephalopods. Anatomy of cephalopods - octopus (order octopoda) octopus vulgaris out of all the cephalopods, the octopus has displayed the highest cognitive prowess, or of any invertebrate for that matter, along with its highly developed eyes, make it worth focusing on [www1.
