Octopusesare extremely smart , withsome scientistsbelieving they were the first intelligent species on Earth . In addition to beingclever enoughto use tools , solve puzzles , do fast one , and recognize humans , the invertebrate are capable of levy Pisces to serve them run . you’re able to witness the remarkable demeanor in the video below .
For their study release inNature Ecology & Evolution , an outside team ofscientistscaptured 120 hour of footage of anOctopus cyanea — also known as the big blue or day octopus — and various Pisces mintage in the depths of the Red Sea .
Each member of the improper squad seemed to have a distinct part . The octopus take on acommander position , leading a chemical group of fish on the hunt for food and superintend operations . Meanwhile , the Pisces get across down smaller fish species and mollusks hiding in crevices . Once they ’ve signaled their target ’s location by hovering above it , the octopus responds by forcing the quarry out into the open . When hunting go swimmingly , both the fish and the octopus welfare — a phenomenon in nature sleep together asmutualism .
The footage also show that octopus do n’t take kindly to freeloader . Some fish species , in particular the blacktip grouper , seem to allow others do the heavy lifting while they waited around for food . In reception , the octopus would lunge at them . Some fish would show aggressiveness toward each other but never toward the octopus , implying the cephalopods model atop the hierarchy .
“ Nobody really knew that octopus have this sophisticated social life history — not with other devilfish , but with other species , ” study co - author Iain Couzin , evolutionary life scientist and director of Germany ’s Max Planck Institute of Animal Behavior , toldPopular Science . While the study throw light on the active ways octopus interact with other mintage , it also raises interrogation . For additional work , the scientist trust to learn whether octopuses recognize item-by-item fish and investigate how much the fish welfare compared to their eight - armed leaders .
