I got a new octopus today. I drove eight hours round trip to pick it up. It was being marketed as a merc, but the shop guy was fairly honest in that he wasn't sure if it was a merc or a baby of something else. It's not afraid of me; its a brave little guy. It's mantle is about 3/8ths of an inch long, and it's arms are about two inches long at best. The best part is that as far as I can tell, it has all eight arms. It may not be afraid of me, but at the same time it's not very social. It will sit there and look at me and fairly ignore me. I acclimatized it for two hours with the turkey baster method. I've also attached some pics. Hopefully you guys can help me ID this bugger!
