Field record
It reads the drone's motor the way other fish read a shadow, and the instant the pitch changes even slightly every fin locks flat against its body. I've timed the stillness at several minutes past when the noise stops, longer than any predator here would ever need to lose interest.
Marginal note: “locks every fin still the instant a motor's pitch changes”

Catching it
A Twilight-tier catch needs at least a Fine Mesh Net— anything under that rating can never hold it, whatever the throw. Bought at the Quartermaster’s counter for 90 crystals. A held net inks this entry for good and pays its ledger bonus on the spot.
