Animals like mantis shrimp see vastly more colors because they have more cone types, revealing a world of hues we can't even imagine.

Key attractions are splashing/erratic movement (signaling distressed prey), low-light conditions (dawn/dusk), and presence of baitfish.
 

What are sharks' weaknesses?

Sharks' weaknesses include their vulnerable gills and eyes, the need for constant movement to breathe (ram ventilation), inability to swim backward, susceptibility to parasites, slow reproduction rates making populations fragile, and sensitivity to freshwater, while humans exploit them through overfishing, habitat destruction, and pollution.
