Myctophid

The astronesthes, or 'eater of the stars,' so called because it feeds entirely upon other 'star-lit' fish called myctophids, is not only endowed with a number of small, luminous organs upon its body, but its fins, and the greater part of its chin-barbels, also emit a bright light.

You're a lucky guy to be eating anything right now. Instead you might easily be feeding the tunny fish and tarpon, to say nothing of the astronesthes and myctophids--
