“…Furthering the work on the slapping action initiated by Sampaio et al (2020) and Bidel et al (2022), we have provided evidence from the slaps of Abdopus sp. for a syntax of actions embodied organization approach to motor control (Flash and Hochner, 2005;Hochner, 2012).…”

“…We believe that the purpose of the action is for the Octopus to protect its den. More recently, Sampaio et al (2020) have reported several similar eld observations of Octopus cyane, which they call 'punching'. Our observations consist of nineteen individual slaps, which were analyzed to understand the behavioral units involved in this complex motor.…”

An octopus, Abdopus sp., can use rotation and translation of its hydrostatic arms, and combine these kinematic behaviors serially and in parallel, on different arms, to ‘slap’ at fish in the wild. Different motor programs may be used in multiple arms producing complex actions. The movements analyzed in this work show how complex the movements of the octopus, in situ, can be, furthering knowledge of this animal’s behavior, as well as furthering understanding of the structure of animal motor control. Stiffening of the flexible muscular hydrostatic arms was found to be important to both primitives of translation and rotation. By combining these kinematic primitives, the octopus is able to maintain flexibility while controlling only a few factors, or degrees of freedom, a concept we term ‘flexible rigidity’. The slapping action of the octopus of interest, Abdopus sp., therefore, gives support for Flash and Hochner’s embodied organization view of motor behavior, as well as their idea that motor primitives can combine syntactically to form a complex action. Our results suggest that the octopus’s ability to use sensory feedback from the position of a moving fish target, along with the feed-forward motor primitives, allows for the building of complex actions at dynamic equilibrium with the environment. Overall, these findings lead to a more realistic view of how a complex behavior allows an animal to coordinate with its environment.

“…Halichoeres sp. ), have been reported to follow octopuses and opportunistically feed on prey they flush-out during foraging events (Mather 1992;Diamant and Shpigel 1985;Strand 1988;Forsythe and Hanlon 1997;Sazima et al 2007;Pereira et al 2011;Sampaio et al 2020). These hunting associations sometimes involve multiple species of fish following a single octopus at the same time.…”

A common feeding association among reef fishes involves nuclear and follower species, where the former disturbs the bottom, during which the latter opportunistically feeds on items exposed. Here, we report such interactions between Western Australian common octopuses (Octopus (cf) tetricus) and brown-spotted wrasse (Notolabrus parilus) observed on eight occasions while snorkeling at four temperate-water reefs along the coast of Perth in Western Australia. We compare the interactions observed to other octopus-fish nuclear-follower associations known. In general, these interactions usually benefit the follower species and could play a significant role on reef trophodynamics.

“…Furthermore, groups are not always formed by individuals of the same species (Sridhar and Guttal, 2018) and some such interspecific groups can cooperate to hunt together, thereby increasing their predation success (Bshary et al, 2006;Diamant and Shpigel, 1985). Decision-making in such groups is being currently investigated (Sampaio et al, 2021). Thus, the wide variety of animal collectives found in nature that can operate intelligently contradicts the notion that intelligence is an aspect or trait of a spatiotemporally cohesive unit composed of relatively identical subunits.…”

Collective intelligence, broadly conceived, refers to the adaptive behavior achieved by groups through the interactions of their members, often involving phenomena such as consensus building, cooperation, and competition. The standard view of collective intelligence is that it is a distinct phenomenon from supposed individual intelligence. In this position piece, we argue that a more parsimonious stance is to consider all intelligent adaptive behavior as being driven by similar abstract principles of collective dynamics. To illustrate this point, we highlight how similar principles are at work in the intelligent behavior of groups of non-human animals, multicellular organisms, brains, small groups of humans, cultures, and even evolution itself. If intelligent behavior in all of these systems is best understood as the emergent result of collective interactions, we ask what is left to be called “individual intelligence”? We believe that viewing all intelligence as collective intelligence offers greater explanatory power and generality, and may promote fruitful cross-disciplinary exchange in the study of intelligent adaptive behavior.
