Literally same.
“Our study arose from the concentration of octopuses at this site, which was unusual,” study author David Scheel, a marine biology professor from Alaska Pacific University, tells“Interactions among octopuses occur very often when there are many animals present, so this location presents the rare opportunity to study behaviors beyond just mating that octopuses bring to bear on interacting with their own kind.
The projectiles were often thrown several body lengths away, and in order to do this, the octopuses had to move their siphon into an unusual position. This difficulty suggests that the throwing behavior was different than what’s needed for their general movements in the water. The octopus returned from a foraging trip 18 minutes earlier and assumed a characteristic feeding posture. As the motion of the throw beings, another octopus reached towards her and they touch as the shells are released. The context of this throw was scored as Eating despite the reach. The vigor was scored high and the pattern as mottled. CREDIT: Godfrey-Smith et al., 2022, PLOS ONE, CC-BY 4.0.
