Which outcome predominates when counterillumination efficiency decreases in a lanternfish?

💡 Explanation

Increased vulnerability happens because camouflage declines, specifically the disruptive coloration enabled via counterillumination, fails; decreased light blends less well with downwelling light, therefore the silhouette becomes more visible to predators, rather than improving signal efficiency underwater.
