Barreleye, Macropinna microstoma. Nominate it for the thing almost nobody knows: the two dark spots above its mouth that everyone reads as eyes are nostrils. The eyes are the green tubes, and they rotate.

Ecologically it’s a hanger-on in the literal sense. It holds itself still in the dark under siphonophore colonies and eats what they catch, which is why there’s almost no footage of it doing anything. A fish that lives by being invisible in the one habitat where being seen is the whole cost.

I read it wrong for years, and the wrong version is the one that gets repeated.
