From: Octopus arm flexibility facilitates complex behaviors in diverse natural environments
An ethogram of octopus behaviors, arm actions, and arm deformations. A hierarchical analysis was used to delineate complex behaviors into arm actions. Arm actions were deconstructed into 4 distinct arm deformations. Species used in the construction of this ethogram included: Octopus vulgaris sensu stricto, O. americanus, and O. insularis.
