Often when Octopus search for a hiding place they aren’t fuzzy and take what ever is laying around. We have been on one of our many underwater cleanup dives and I lifted the Can up but fortunately saw there was an Octopus hiding inside so i put it back where i found it as it could have been that she laid her eggs inside the can too. and the Oceans don’t die from one Aluminum can!
Octopus can squeeze through very tiny holes as they only have one small Skull bone. They are invertebrate and adapted to life underwater and are very clever!
