Knifejaw fish can detect tiny thermal differences to navigate complex trench environments without relying on vision alone.
Knifejaw fish inhabit deep trenches where light barely penetrates, relying on infrared-sensitive retinal cells for orientation. Juvenile marine researchers noted that these fish could detect minute thermal gradients created by other organisms or environmental features. This ability allows them to navigate complex underwater landscapes while avoiding predators and locating prey. Infrared detection is integrated with mechanoreception to form a multi-sensory map of the trench floor. Observations indicate that knifejaw fish respond to temperature differences as small as 0.01°C. Such precision enhances survival and foraging efficiency in extreme, high-pressure environments. Evolution has optimized this sensory system to compensate for near-complete darkness. Infrared sensitivity also aids in schooling behavior and territory mapping. Knifejaw fish demonstrate that even navigation, not just hunting, can benefit from thermal perception in abyssal habitats.
