The "ring" part is the overall shape of the gulper eel eating its own tail. My concept was to do an ouroboros (traditionally a snake eating its own tail), with the overall shape being the ring, the bait hopefully being obvious (the tail), and the mindless also hopefully obvious (eating yer own tail not particularly mindful LOL). Thanks for the complement! My kids are obsessed with deep sea creatures and had been talking about gulper eels so that was on my mind. I watched a cool clip last night, might be the one you referenced, of researchers who get really excited when a gulper eel swims up then inflates itself like a balloon :)
