Octopus warringa/huttoni It's a complex that's hard to ID and frankly I wasn't in a position to do a sucker count (too busy commenting on the parentage of the staff member who puts them in the tank and doesn't tell anyone or in one case trying NOT to comment, as we had a family with small children who were enjoying watching me "play" with the octopus......I know cos they told me so!!!!)
I tend to favor the tag on the glass. I think in all the octopuses I have had, only 2 have gotten "ahold" of me. For some reason and maybe it's not a bad idea, I am very cautious about getting nipped. Thinking about it, when Jess was 5 she got nipped by Inklet. Seeing that recent reaction to a bite, and being she is "allergic" to several things, probably not a good idea to ever let her get that close again.
