The sand-dwelling octopus Macrotritopus defilippi was filmed or photographed in five Caribbean locations mimicking the swimming behavior (posture, style, speed, duration) and coloration of the common, sand-dwelling flounder Bothus lunatus. [...] Key Result Each species was exceptionally well camouflaged when stationary, and details of camouflaging techniques are described for M. defilippi. Octopuses implemented flounder mimicry only during swimming, when their movement would give away camouflage in this open…Expand
The evolution of conspicuous facultative mimicry in octopuses: an example of secondary adaptation?
TLDR
Relationships between behavioural and morphological elements of conspicuous flatfish swimming in extant octopodids, and reconstructed ancestral states, are examined to examine potential influences on the evolution of this rare defence mechanism and to explore whether conspicuous Flatfish swimming may be an exaptation that usurps a previously evolved form of locomotion for a new purpose.

Rapid Adaptive Camouflage in Cephalopods
TLDR
Benthic shallow-water cephalopods have rapid adaptive camouflage so that they can move about freely (foraging, finding mates, etc.) in multiple ecohabitats and avoid visual predation by tuning their camouflage to nearly any visual background in their natural ranges. Expand
Flamboyant cuttlefish behavior: Camouflage tactics and complex colorful reproductive behavior assessed during field studies at Lembeh Strait, Indonesia
TLDR
This small species of cuttlefish is cryptic and spends the vast majority of each day in a variety of highly camouflaged body patterns. Expand
Behavioral dynamics provide insight into resource exploitation and habitat coexistence of two octopus species in a shallow Florida lagoon
TLDR
Coexistence between these two species results primarily from differences in resource use (habitat and diet) and temporal and spatial heterogeneity and Incorporating species-specific behavioral habits is a key tool for understanding octopus ecology and coexistence. Expand
Wild observation of putative dynamic decapod mimicry by a cuttlefish (Sepia cf. smithi)
TLDR
This observation is the first wild record of decapod mimicry by a cuttlefish, tentatively identified as Sepia smithi, during a non-targeted BRUVS study on Australia’s Northwest Shelf. Expand
Unique arm-flapping behavior of the pharaoh cuttlefish, Sepia pharaonis: putative mimicry of a hermit crab
TLDR
A previously undescribed arm-flapping behavior of the pharaoh cuttlefish, Sepia pharaonis, observed in captivity is reported, including possible mimicry of a hermit crab, considering the situations in which the behavior was observed. Expand
Evidence of mimicry of gelatinous zooplankton by anguilliform leptocephali for predator avoidance
TLDR
Video recordings of leptocephali in surface waters at night at Osprey Reef in the Coral Sea revealed that 6 of 21 larvae filmed displayed a distinct shape-change behavior of curling up into fully or partially coiled shapes, which may result in mimicry of gelatinous zooplankton organisms. Expand
An ethogram for Benthic Octopods (Cephalopoda: Octopodidae).
TLDR
A general ethogram for the actions of the flexible body as well as the skin displays of octopuses in the family Octopodidae is constructed, suggesting that, despite having flexible muscular hydrostat movement systems producing several behavioral units, simplicity may underlie the complexity of movement and appearance.

First detailed description of the burying behaviour of a bottletail squid, Sepiadarium kochii Steenstrup, 1881
TLDR
The burying pattern of a single tropical bottletail squid Sepiadarium kochii Steenstrup, 1881 is analysed for different behavioural characteristics and a comparison of the burying patterns of closely related bobtail squids is drawn. Expand

Mimicry and foraging behaviour of two tropical sand‐flat octopus species off North Sulawesi, Indonesia
TLDR
The key finding was that octopuses used flounder mimicry only when their movement would give away camouflage in this open habitat, which is a highly unusual circumstance of a guild of small, long-armed octopus species that shared the same habitat, den sources, food, activity period, and some behaviours. Expand
Octopus mimicking its follower reef fish
TLDR
It is suggested that the feeding association commonly found between O. insularis and C. fulva minimized the evolutionary costs for the origin of mimicking by the octopus, a form of protection against visually‐oriented predators. Expand
Field and laboratory behavior of "macrotritopus larvae" reared to Octopus defilippi Verany, 1851 (Mollusca: Cephalopoda)
TLDR
Morphological examination of 106 specimens from the Atlantic indicate that all macrotritopus “larvae” from this ocean are O. defilippi, and the transition from a planktonic to benthic life may be controlled to ensure widespread distribution on to a suitable habitat. Expand
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
TLDR
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. Expand
Dynamic mimicry in an Indo–Malayan octopus
TLDR
It is revealed that the ‘mimic octopus’ emerges during daylight hours to forage on sand substrates in full view of pelagic fish predators, allowing it to enhance further the benefits of mimicking toxic models by employing mimicry according to the nature of perceived threats. Expand
Ethogram of Abdopus aculeatus (d'Orbigny, 1834) (Cephalopoda: Octopodidae): can behavioural characters inform octopodid taxomony and systematics?
TLDR
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. Expand

Principal features of the mating system of a large spawning aggregation of the giant Australian cuttlefish Sepiaapama (Mollusca: Cephalopoda)
TLDR
By aggregating to spawn and spawning asynchronously, females may also increase male–male competition through indirect mate choice and have implications for understanding the species' life history and the impacts of fishing. Expand
Cephalopod dynamic camouflage: bridging the continuum between background matching and disruptive coloration
TLDR
The chief characteristics of the three major body pattern types used for camouflage by cephalopods are defined: uniform and mottle patterns for background matching, and disruptive patterns that primarily enhance disruptiveness but aid background matching as well. Expand
