Field record
Every jelly logged above this depth carries some kind of light of its own; the notes on this one specify that it does not, and that its absence was more unsettling on sonar than any glow would have been. It has been recorded only as a gap where a return should be.
Marginal note: “the only jelly on record that carries no light”
