Social tolerance in Octopus laqueus—A maximum entropy model

It is found that O. laqueus will socially tolerate other individuals by sharing tanks and dens and with typically no loss to cannibalism or escape, but animals also exhibit significant levels of social repulsion, and individuals often chose a solitary den when given the option.

Social tolerance in Octopus laqueus - a maximal entropy model

It is found that O. laqueus will socially tolerate other individuals by sharing tanks and dens, including several animals in contact and sharing a den under den-limited conditions, and with typically no loss to cannibalism or escape.

Body coloration as a dynamic signal during intrasexual communication in a cichlid fish

Analysis of body coloration in male P. taeniatus revealed a change in within-individual color intensity and colored area after interaction with a male competitor, which explained dominance established between the two contestants.

A second site occupied by Octopus tetricus at high densities, with notes on their ecology and behavior

Wild octopuses (Octopus tetricus) are reported living at high density at a rock outcrop, the second such site known, and behavior at this second site confirms that complex social interactions also occur in association with natural substrate, and suggests that social interactions are more wide spread among octopus than previously recognized.

Tactical Tentacles: New Insights on the Processes of Sexual Selection Among the Cephalopoda

It is concluded that sperm competition and possibly cryptic female choice are likely to be critical determinants of which individuals' alleles get transferred to subsequent generations in cephalopod mating systems.

A Conserved Role for Serotonergic Neurotransmission in Mediating Social Behavior in Octopus

Odor Coding of Nestmate Recognition in the Eusocial Ant Camponotus floridanus

These studies provide direct evidence that the antennae and odorant receptors are necessary for mediating aggression towards non-nestmates and contribute to a long-standing interest in odor coding and the molecular neuroethology of nestmate recognition.

In the line of fire: Debris throwing by wild octopuses

Wild octopuses at an Australian site frequently propel shells, silt, and algae through the water by releasing these materials from their arms while creating a forceful jet from the siphon held under the arm web, as suggested by several kinds of evidence.

Chemical cues correlate with agonistic behaviour and female mate choice in the southern blue-ringed octopus, Hapalochlaena maculosa (Hoyle, 1883) (Cephalopoda: Octopodidae)

Results suggest that female H. maculosa can use chemosensory cues to discriminate the sex, and possibly identity, of conspecifics and that this information might influence their mate choice, although the mechanisms underlying these responses and subsequent copulatory access to females by males remain unknown.

Do cuttlefish (Cephalopoda) signal their intentions to conspecifics during agonistic encounters?

Abstract Abstract. Male cuttlefish adopt a specific body pattern during agonistic behaviour called the Intense Zebra Display. Some components of the Display were variable, especially the chromatic

Apparent movement in a visual display: the ‘passing cloud’ of Octopus cyanea (Mollusca: Cephalopoda)

This visual display is presumed to be a startle attempt, producing apparent movement by selective sequential chromatophore expansion to induce a crab to move without the drawback of motion by the octopus itself.

Ethogram of Abdopus aculeatus (d'Orbigny, 1834) (Cephalopoda: Octopodidae): can behavioural characters inform octopodid taxomony and systematics?

Aspects of the dymantic display, mating system, activity patterns, and habitat use appear similar to those expressed by other members of Abdopus, as well as the large sister taxon Octopus cyanea, suggesting that these behaviours may be conserved throughout the evolution of these octopuses.

Dominance and den use in Octopus bimaculoides

The hypothesis that dominance determines den use when dens are limited and vary in quality was tested and it is suggested that O. bimaculoides is able to recognize whether an individual is dominant or subordinate to it and that this recognition occurs quickly.

Crypsis, conspicuousness, mimicry and polyphenism as antipredator defences of foraging octopuses on Indo-Pacific coral reefs, with a method of quantifying crypsis from video tapes

The results suggest that, while foraging, the overall strategy is to use polyphenism to produce «apparent rarity» of any single phenotype (or search image) through mechanisms of crypsis, conspicuousness and mimicry, all of which are guided by keen vision in this marine invertebrate.
