Fractions from an organic extract from fresh octopus (Paraoctopus limaculatus) were studied for biological activities such as antimutagenic and antiproliferative properties using Salmonella tester strains TA98 and TA100 with metabolic activation (S9) and a cancer cell line (B-cell lymphoma), respectively. A chloroform extract obtained from octopus tentacles was sequentially fractionated using t...

In the Octopus each user has a single PC in the network that is used to run applications. Any machine in the Internet can be used as a user s terminal to access the Octopus, which means that the latency between the user interface devices and the central system may be utterly high. Multiple machines are used as terminals, simultaneously. We have devel­ oped a unique user interface file system fo...

The Sydney octopus (Octopus tetricus) occurs in unusual numbers on a shell bed of its prey remains that have accumulated as an extended midden where additional octopuses excavate dens. Here, O tetricus are ecosystem engineers, organisms that modulate availability of resources to other species and to their own species by causing physical state changes in materials. A community of invertebrate gr...

During their 3rd week of life, 73 Octopus bimaculoides were observed to test whether discrete behaviors could be grouped reliably to reflect dimensions of temperament. Frequencies of behaviors during Week 3 were subjected to principal-components analysis (PCA), resulting in 4 components (active engagement, arousal/readiness, aggression, and avoidance/disinterest) that explain 53% of the varianc...

Octopuses will make detours in order to reach prey that is not directly accessible to them. Using the apparatus shown in Fig. 1 Wells (1964) trained octopuses to make detours to reach crabs shown in the feeding compartments flanking the central corridor. Eight out of twenty-nine animals tested completed detours successfully on entering the corridor for the first time at their first trial. The r...

Gurita in English is called Octopus which often refers only to animals of the genus Octopus. This creation based on results research octopus used as a symbolic brand icon reveal existence current social, cultural, economic and political realities. In interpreting characteristics shape nature Octopus, it expressed through metaphorical visual language represent value rajas tamas that permeates hu...

A Chatbot is a type of conversational agent or a computer program which has been designed to simulate an intelligent conversation with one or more human users via auditory or textual methods. Chatbots can be used as an exciting intelligent mechanism to interacting with computers. Undisputedly, Chatbots revolutionize the next generation of human-machine and machine-machine interaction in the con...

The Octopus arm is a highly versatile and complex limb. How the Octopus controls such a hyper-redundant arm (not to mention eight of them!) is as yet unknown. Robotic arms based on the same mechanical principles may render present day robotic arms obsolete. In this paper, we tackle this control problem using an online reinforcement learning algorithm, based on a Bayesian approach to policy eval...

Depredation of southern rock lobster (Jasus edwardsii) within fishing gear by the Maori octopus (Pinnoctopus cordiformis) has economic and ecological impacts on valuable fisheries in South Australia. In addition, depredation rates can be highly variable resulting in uncertainties for the fishery. We examined how in-pot lobster predation was influenced by factors such as lobster size and sex, se...
