Hey y'all. So our (approximately) year old giant Pacific octopus has a white mark/abrasion/cut on her head. It's circular in shape and about an inch and a half in diameter. She has been jetting around her tank an awful lot lately, so I'm assuming she's been hitting her head on things and that's where the cut came from. I'm also assuming this is fairly common with GPOs, since many of the GPOs I used to work with at my old volunteer jobs had the same marks on their heads, too. But again, that's an assumption, and I could be wrong. SO! How common is this occurence with octopuses? Should we be concerned? Is there anything we should keep an eye out for that might imply it's getting infected? Thanks!
