Whalefish can detect both prey and predators by sensing tiny heat emissions in near-total darkness.
Whalefish, small deep-sea midwater predators, possess specialized infrared-sensitive retinal cells that allow detection of faint heat emissions. Juvenile marine scientists observed that whalefish adjust vertical movement and orientation based on thermal cues to locate prey and avoid threats. Infrared detection improves hunting efficiency for small fish and crustaceans in nearly pitch-black environments. Combined with lateral line and chemical detection, the sensory system provides multi-modal awareness. Studies indicate detection of temperature differences as slight as 0.003°C. Infrared vision also aids schooling and spatial orientation in midwater populations. Evolution has optimized this sensory adaptation for energy efficiency in extreme low-light environments. Whalefish rely on thermal cues not just for feeding but for survival against predators. Infrared perception demonstrates the adaptive ingenuity of deep-sea giants in challenging habitats.
