Summary: 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. [...] Key Result Positive feedbacks included the accumulation of shell debris, increasing shelter availability for additional octopuses and aggregating fish.Expand

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

Variation in Octopus bimaculatus Verrill, 1883 Diet as Revealed through δ13C and δ15N Stable Isotope Analysis: Potential Indirect Effects of Marine Protected Areas
TLDR
Results suggest octopus foraging behavior could be influenced by variation in predation risk reveal an indirect impact of diurnal predator recovery in the MPA. Expand
Octopus engineering, intentional and inadvertent
ABSTRACT We previously published a description of discovery of a site where octopuses live in an unusually dense collection of individual dens near one another in a bed of scallop shells amid a rock… Expand
Signal Use by Octopuses in Agonistic Interactions
TLDR
It is shown by field observation that in a shallow-water octopus, Octopus tetricus, a range of visible displays are produced during agonistic interactions, and these displays correlate with the outcome of those interactions. Expand

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. Expand
TIME-AVERAGING AND STRATIGRAPHIC RESOLUTION IN DEATH ASSEMBLAGES AND HOLOCENE DEPOSITS: SYDNEY HARBOUR'S MOLLUSCAN RECORD
Abstract: Time-averaging has evolved from an unrecognized variable in paleoecological analyses to a key concept in understanding the dynamics of sedimentary systems and the formation of fossil… Expand

Effects of octopus predation on motile invertebrates in a rocky subtidal community
TLDR
It is concluded that octopus predation can dramatically reduce prey densities when octopuses are unusually common, but that in most years the abundance ofoctopuses is too low to disrupt the basic patterns of prey abundance that result from other processes. Expand
AEROBIC METABOLISM AND DIETARY ECOLOGY OF OCTOPUS RUBESCENS
TLDR
Octopus rubescens is the most common shallow water octopus on the west coast of North America, and seems to be a likely candidate to exert considerable influence on lower trophic levels through its energy budgeting by the species. Expand
Foraging, feeding and prey remains in middens of juvenile Octopus vulgaris (Mollusca: Cephalopoda)
Juvenile Octopus vulgaris foraged by chemotactile exploration, mainly in crevices and under rocks. They caught small crustaceans and molluscs, including Lima bivalves, and preferred crabs and Lima in… Expand
Variability in the Diet Specialization of Enteroctopus dofleini (Cephalopoda: Octopodidae) in the Eastern Pacific Examined from Midden Contents
TLDR
Examination of variation in dietary specialization of Enteroctopus dofleini, the giant Pacific octopus, from Puget Sound to the Aleutian Islands, as represented in midden remains found an influence of items per midden and prey species maximum size on these indices. Expand
Habitat selection and shelter use by Octopus tetricus
TLDR
This study suggests that Octopus telricus are associated with rocky reef habitats during the breeding season, while a considerable portion of their life may be spent in soft-sediment habitats. Expand
Octopuses influence den selection by juvenile Caribbean spiny lobster
TLDR
Field manipulations of artificial dens showed that the distribution of lobsters was significantly influenced by the proximity of octopuses, and lobsters were significantly less likely to inhabit dens within 2 m of an octopus den, but this strong negative effect disappeared when dens were 10 m apart. Expand
Den ecology of Octopus vulgaris Cuvier, 1797, on soft sediment: availability and types of shelter
TLDR
It is concluded that the availability of solid materials necessary for den construction is a limiting factor for the distribution of O. vulgaris on soft sediment. Expand
Den associates of the giant Pacific octopus, Octopus dofleini (Wulker)
TLDR
A variety of organisms were consistently associated with the dens or debris accumulating at the den arising from the feeding behaviour of octopus, including fishes, sea stars and crabs. Expand
Interspecific feeding associations of groupers (Teleostei: Serranidae) with octopuses and moray eels in the Gulf of Eilat (Agaba)
TLDR
Temporary interspecific feeding associations between groupers (Serranidae) and moray eels or octopuses in the Red Sea were observed 41 times during over 400 scuba dives, suggesting that this is a learned behavior which increases food diversity and feeding efficiency. Expand
