Octopus mercatoris Norman: (not listed) Nesis: synonym for Joubini, 5cm ML max, but 2-3cm ML typical
That list and its format have me wondering about the possible importance of mantle Max amd Mantle typical sizes. Trapper was in the Max category but her young are the smaller, typical size at 10 + months. It appears AM's hummelincki, Tuvalu was of the typical (I don't have a reference on the others of that group) and Octane is in the max range. The differences are substantial and I am wondering if anyone in the biology group has done any kind of study on why there is such a difference and if it plays any part in longevity.
Until I saw the list, I was thinking the smaller sizes of my tank raised Mercs was directly related to the size of their environment, now I don't think that is the case and I think male vs female can be ruled out too.
Also, in the case of hummelincki, the girth of the mantle, web and arms is at least twice that of the Merc and none of the statistics mentions a combination of length and width, which, in the case of any octopus, is an important measuring consideration.
