“…We see modal action patterns (sensu Barlow, 1968) expressed, yet there is much more to know. Laboratory research such as that outlined by Hochner (2013) and following the examples presented in Pellis et al (2014) will begin to elucidate the neural, physical, and sensory background of the organization of the behaviors. Yet field observation is also necessary to build up the repertoires of particular species, and Huffard's (2007a) work is an excellent example.…”

“…Over several decades, researchers focused on neural pattern generators and the resulting rhythmic movement output (Pearson, 1993), in invertebrate and vertebrate animals. Pellis, Pellis, and Iwaniuk (2014) instead emphasized that we must examine the combination of neural rules, environmental input resulting in end-point perceptual results, and the physical constraints of the animal's body, which underlie Hochner's (2013) Embodied Organization approach. For an animal such as the octopus with a muscular hydrostat movement system that can use many degrees of freedom (Kier & Thompson, 2003), such physical constraints may be less important.…”

“…For an animal such as the octopus with a muscular hydrostat movement system that can use many degrees of freedom (Kier & Thompson, 2003), such physical constraints may be less important. Neural organization and routines of motor learning may result in the biases that we see as fixed patterns, and what seem to be complex routines may end up resulting in simple sensory end points (Pellis et al, 2014).…”

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
