Thank you everyone for the warm
and the complimets on the pics. Tako is still blushing and finding it hard to deal
with his newfound fame!
The more I look at him, the more I think hes not a defilippi. I, too, have Mark Norman's guide, as well as a divers reference for carribean species. Defilippi seemed the most likely because of it's overall pattern, long arms, close proximity, and ability to sever arms. I forgot to mention when I got him he had seven arms and a stump! If you look closely at pic six where hes on the glass you can see his third right arm is severed near the base. It almost definitely was lost during collection because its already regrowing! Its about 3/4" long.
But if he's not a defilippi, then what could he be? He usually wears the coarse sand pattern you see in the photos. At night he turns greener and erects all his 3D camo, which can be pretty extreme; more so than most species it seems. Nancy, after looking at his arms more I think the second ang fourth pairs are the longest, but its hard to tell cuz hes only has one third arm! I've occasionaly seen him do the boldly striped display that your O. aculeatus seems to favor, Mucktopus. Possibly hes another member of the horridus species complex? What does everyone think?
