All of that sounds sort of right. I've also read about octopi punching fish for fun. I commented to Bob that it didn't really sound like me, but he said "oh, I don't know, you invite in Jehovah's Witnesses and argue religion with them." so, yeah. That too.
This painting drove my recent love of landscapes right out of the water, they were good for breaking the stranglehold of other people's art and what the market wants but this one brought me back to when I wanted to be a marine biologist. I've whined for fifty years about being sidetracked from that goal, but if I'm honest I will admit that I don't actually like science, by my reckoning it puts the dogma of religion in the shade and is mostly concerned with drilling down on minutiae while I am interested in the global POV. What I really wanted was to see these beautiful underwater things and maybe reproduce them with art materials and get paid for it. Now that I'm retired the getting paid for it would be nice but not so essential, it seems that life seems to take care of itself. I wouldn't sell this one anyway, it's mine.
