Rattail fish can detect prey using infrared perception even when it is camouflaged or buried under sediment in the deep sea.
Rattail fish, benthopelagic species of deep-sea trenches, possess infrared-sensitive cells in their retinas that detect minuscule heat differences. Juvenile researchers observed that these fish can orient and strike at prey hidden under sediment or dimly illuminated water using only thermal cues. Infrared detection complements lateral line and olfactory systems, creating a multi-modal hunting strategy. Observations show they respond to temperature differences as low as 0.003°C. This sensory ability reduces energy expenditure and increases predation efficiency in food-scarce environments. Infrared perception also provides early warnings of approaching predators. Evolution has refined these capabilities to maximize survival in high-pressure, low-light habitats. The adaptation illustrates that deep-sea giants exploit all available environmental information to thrive. Rattail fish infrared sensing underscores the complexity of sensory evolution in abyssal species.
