great big fishes

I once saw a Mola mola from on board a smallish off-shore boat. We were out to see whales. The sunfish was probably out slurping up jellyfish at the surface of the water. They do that, apparently. We stood at the rail and peered down at the enormous fish hanging in the water scant meters off the side as we listened to the guide on the loudspeaker tell us all about these animals and their jellyfish-eating habits. The fish itself, meanwhile, ceased all such activity, preferring to let itself float up parallel with the surface of the water, the better to turn one great, alien, blue-ringed eye upon us up in the boat, looking down at it.
