“…Yet some components of display repertoires may serve as distinct characters. The exposure of iridophores concentrated in particular areas delineates the maculated or ocellate octopuses, although so far no one has found either a function or a phylogenetic background for the ocellus displays (Norman, 1992b). The patterns of blue rings are distinct for the members of the venomous genus Hapalochlaena and are hypothesized to be an antipredator warning display (Mäthger et al, 2012).…”

The present paper constructs a general ethogram for the actions of the flexible body as well as the skin displays of octopuses in the family Octopodidae. The actions of 6 sets of structures (mantle-funnel, arms, sucker-stalk, skin-web, head, and mouth) combine to produce behavioral units that involve positioning of parts leading to postures such as the flamboyant, movements of parts of the animal with relation to itself including head bob and grooming, and movements of the whole animal by both jetting in the water and crawling along the substrate. Muscular actions result in 4 key changes in skin display: (a) chromatophore expansion, (b) chromatophore contraction resulting in appearance of reflective colors such as iridophores and leucophores, (c) erection of papillae on the skin, and (d) overall postures of arms and mantle controlled by actions of the octopus muscular hydrostat. They produce appearances, including excellent camouflage, moving passing cloud and iridescent blue rings, with only a few known species-specific male visual sexual displays. Commonalities across the family suggest that, despite having flexible muscular hydrostat movement systems producing several behavioral units, simplicity of production may underlie the complexity of movement and appearance. This systematic framework allows researchers to take the next step in modeling how such diversity can be a combination of just a few variables. (PsycINFO Database Record

“…A log-normal plot range of species considered. Mantle lengths of males of Callistoctopus aspilosomatus (Norman, 1993a) that are "elongate" were not longest spermatophore length for each species was plotted versus the log of the longest mantle length for that species. Log-transformation equalizes measurement error over the wide size range considered, minimizes any error the effect of outliers (Bookstein et al, 1985;Strauss, 1985 C. alpheus (Norman, 1993a) 3 2 74 68.5 Norman (1993a) C. aspilosomatis (Norman, 1993a) 2 3 45 39 Norman (1993a) C. dierythraeus (Norman, 1993a) 4 1 135 102 Norman (1993a) (ML; SpL) and the data source.…”

Female octopuses are thought to copulate with multiple males and store sperm for months prior to spawning, a generalization that has led to hypotheses of strong sperm competition in the wild, force indirect tests of this generalization. Male reproductive effort, already high in these generally semelparous animals, is predicted to increase further with sperm competition. mantle length. The median spermatophore count was 24; nearly one-third of the species had 60 or more spermatophores. Of these, 16 were species of Eledone, Octopus (Octopus) or Abdopus, supporting the hypothesis that related species share similar spermatophore counts; relationships of the other species are poorly known. Spermatophores of these 24 speciesCallistoctopus spp. carry nine or fewer spermatophores, as do deep-sea species of Bathypolypus, and the Southern Ocean endemic and deep-sea octopus clade.phore counts among species may offer insight into male response to sperm competition and

“…Cephalopods also received the top score for the predation process (FI = 1), despite the literature being largely restricted to their taxonomy and diversity (Roper & Hochberg 1987, Norman 1992, Norman & Finn 2001, Rosa et al 2019. Surprisingly little information exists on their functional ecology on the GBR and in general (Ponder et al 2002).…”
