Unless this is O. zonatus, which I doubt, I can add a bit of information on shipping and care in the aquarium. In the late 70's I brought several from Panama to Berkeley. I had no idea what I was doing and transported and kept them as I would stomatopods. I didn't lose any in transit (despite being very cold) and one female laid 5 clutches over several months. They must be hardy since I freely admit that I didn't have a clue how to keep them. I must say, it perhaps was not a bad thing that I treated them like stomatopods. They live in the same type cavities, occur in the low intertidal where they occasionally are exposed (and exist for a few water on just the water in the cavity), and are thermally tolerant. This was still a couple of years before Rodaniche published on them. I didn't even know that it was a big deal that the females were iteroparous. This is probably why I've been kicking myself all these years. I had the opportunity to study them and I totally blew it. It was my experience with O. chierchiae that was partly responsible for my becoming interested in pygmy octopuses and start to study them.
