Is it a fish...or a robot spy? 🤖🐟 #NatGeoExplorers and scientists Piero__Amodio, EduSilvaSampaio, Alex.Schnell, santiidiaz6, Isabella Fiorello (isa_fiore92), Greta Cwikla, Donato Romano and Liang Li developed a special, human-controlled robot shaped like a fish to better understand collaborative hunting behavior between the day octopus and coral trout on Australia's Lizard Island. Acting as an artificial hunting partner during ocean experiments, the robot allows researchers to observe and study these interspecies interactions directly. Photos by Explorer dr.shireenrahimi
