The minnow was eating krill; so I don't think it can claim a moral high ground over the dolphin feasting on minnows.

I suspect that the shrinking gills, the hole being drilled in the back of the head, the anemic feeling and the need to swim toward the surface are all connected.

@hivebuzz shows my account is pretty much all 9s; I don't think I will know the answer to this puzzle until later.
