← Nature & AnimalsWhich outcome predominates when counterillumination efficiency decreases in a lanternfish?
A)Increased vulnerability to predation from below✓
B)Enhanced intraspecies communication effectiveness underwater
C)Decreased mating success via signal obfuscation
D)Elevated energy expenditure for light production
💡 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.
