← Nature & AnimalsWhich risk dramatically increases within densely packed bioluminescent fish schools?
A)predator attraction via cumulative light✓
B)reduced oxygen due to higher density
C)increased detection of subtle movement
D)greater temperature variance in deep waters
💡 Explanation
Predator attraction increases because cumulative bioluminescence creates a brighter, farther reaching signal; this is due to increased visual predation, therefore predators are attracted, rather than deterred and schooling may offer other benefits at an oxygen/detection cost.
