Monty,
Great question but I wish you had asked it about 6 months ago. It never occurred to me to measure them on a regular basis and sadly, I could have since these two are out on the glass nightly. My gut feel is that they have started shrinking in total mass but arm length seems relatively stagnent. The mantle is hard to judge. One night it may appear very small (relative to "normal" and to each other) but as they swim, the mantle gets fuller and they look "normal" again to me. I will try to start taking some measurements to at least give a proper recording of their size at one year. I can say that none of them ever reached the size of Trapper. A rough guess would be 2/3 her size. The males are all about the same size and Miss Broody appeared slightly larger the very few times I saw her out of her den.
