Which purpose does counterillumination achieve via bioluminescence in marine organisms?

💡 Explanation

Counterillumination diminishes silhouette visibility to predators because camouflage relies on matching downwelling light via bioluminescence; therefore predators can’t easily see the organism, rather than attracting prey which would be a different tactic.
