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.

Seasonal occurrence of Japanese pygmy octopus Octopus parvus in the intertidal zone

It is found that the octopus inhabits the intertidal zone of the study site from August to January, during which time it appears to move from the high to low intert tidal zone, and subsequently migrates to the subtidal zone.

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.

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

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.

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.

Effects of octopus predation on motile invertebrates in a rocky subtidal community

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.

AEROBIC METABOLISM AND DIETARY ECOLOGY OF OCTOPUS RUBESCENS

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.

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

Variability in the Diet Specialization of Enteroctopus dofleini (Cephalopoda: Octopodidae) in the Eastern Pacific Examined from Midden Contents

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.

Habitat selection and shelter use by Octopus tetricus

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.

Octopuses influence den selection by juvenile Caribbean spiny lobster

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.

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.

Den associates of the giant Pacific octopus, Octopus dofleini (Wulker)

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.

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.
