This study exposed 8 Enteroctopus dofleini separately to 2 unfamiliar individual humans over a 2-week period under differing circumstances. [] Key Method One person consistently fed the octopuses and the other touched them with a bristly stick. Each human recorded octopus body patterns, behaviors, and respiration rates directly after each treatment. At the end of 2 weeks, a body pattern (a dark Eyebar) and 2 behaviors (reaching arms toward or away from the tester and funnel direction) were significantly…
Octopus bimaculoides Activity Depends on Who Their Neighbor is
TLDR
It is found that laboratory-housed Octopus bimaculoides were more active, and more of their activity occurred in proximity to a neighboring tank when housed in social situations similar to their natural habitation, compared to when housed alone.
I Know My Neighbour: Individual Recognition in Octopus vulgaris
TLDR
Octopuses appear able to recognise conspecifics and to remember the individual previously met for at least one day in the first experimental study showing the occurrence of a form of IR in cephalopods.

TLDR
The ability of ocean and terrestrial animals to relate to one another in ways that are reciprocal, if not equally balanced, and illustrates this with the examples of octopuses is explored.
Can cuttlefish learn by observing others?
TLDR
The results indicate that most cuttlefish did not learn by observing others, but individual differences exist, and some cuttle fish may have the potential of observational learning/conditioning within their cognitive capacities.
What is in an octopus's mind?
TLDR
The actions of octopuses can be domain general, with flexible problem-solving strategies, enabling them to survive “by their wits” in a challenging and variable environment.
Where Is It Like to Be an Octopus?
TLDR
This manuscript explores the possibility that the octopus arm is capable of supporting an idiosyncratic field of consciousness, and investigates the likelihood that there is something it is like to be anOctopus arm.
Behavioural aspects of the New Zealand octopus Pinnoctopus cordiformis: acclimation, sleep deprivation and responses to video stimuli
TLDR
Pinnoctopus cordiformis did not appear to possess homeostatic regulation of sleep behaviour following sleep deprivation, indicating that the variability in sleep and rest patterns seen in aquatic mammals and elsewhere also exists between octopuses of different species.
Care and Enrichment for Captive Cephalopods
TLDR
Cephalopods’ abilities are far-ranging and must be considered when providing captive care, to not only provide adequate welfare and well-being but to also ensure normal development.
Cephalopod Behavior: From Neural Plasticity to Consciousness
TLDR
It is proposed that cephalopods - particularly the octopus - provide a unique test case among invertebrates for examining the properties and conditions that afford a basal faculty of consciousness, and identifies future research directions for the study of consciousness in these tantalizing animals.
Cognition and Recognition in the Cephalopod Mollusc Octopus vulgaris: Coordinating Interaction with Environment and Conspecifics
TLDR
The examination of data and observations available provide the basis for asking new stimulating questions about the cognitive abilities of octopuses and their allies and open novel scenarios for future comparative research.

Personalities of octopuses (Octopus rubescens)
TLDR
Large individual differences are commonly found in the behavior of octopuses, even in standardized situations, and the similarity of these factors to dimensions of personality in humans and individual differences in animals suggests there may be commonalities in such variation across phyla.
Octopuses (Octopus bimaculoides) and cuttlefishes (Sepia pharaonis, S. officinalis) can conditionally discriminate
TLDR
It is demonstrated that cephalopods are capable of conditional discrimination and extend the limits of invertebrate complex learning.
Inhibitory learning and memory in the lesser octopus (Eledone cirrhosa)
TLDR
The results indicated that octopi are capable of inhibitory learning, they can transfer the learned inhibition to a natural feeding situation, and they remember the learned inhibitions for at least 37 days.
Chemotactic behaviour inOctopus
TLDR
The suckers on the arms of theOctopus are believed to be the sensory structures responsible for the observed behaviours and the chemical sense may be an important adjunct to vision in the search for food under natural conditions.
Interactions of juvenile Octopus vulgaris with scavenging and territorial fishes
TLDR
The octopuses excluded from potential foraging areas were made more localizable by predators due to the presence of slippery dicks, and these common interactions are another manifestation of Cephalopods’ competition with fish in the marine environment.
Observational Learning in Octopus vulgaris
TLDR
Untrained Octopus vulgaris (observers) were allowed to watch conditioned Octopus(demonstrators) perform the task of selecting one of two objects that were presented simultaneously and differed only in color to show that observational learning can occur in invertebrates.
Visual Acuity in Octopus Pallidus and Octopus Australis
TLDR
Animals rapidly reached performance levels of better than 80% correct responses on all discriminations, and the behaviour of the two species is very similar to that of O. vulgaris, except that they accept less food per day, so fewer trials could be given.
A new approach to octopuses' body pattern analysis: A framework for taxonomy and behavioral studies*
TLDR
The strong degree of similarity among photographs supports previous taxonomic studies that pointed to morphological similarity within this species from the oceanic islands of northeastern Brazil and distinguishes between morphological and physiological units of the display system.
Visual responses by octopus to crabs and other figures before and after training
TLDR
The experiments show that information stores associating a given figure with either food or shock can be set up after removal of the vertical lobes but tend to dissipate more rapidly than in a normal octopus.
