Lanternfish can detect tiny temperature differences in the water, allowing them to find dense prey patches during night-time vertical migrations.
Lanternfish, one of the most abundant deep-sea species, possess infrared-sensitive retinal regions enabling detection of slight temperature variations caused by aggregations of plankton and small fish. Juvenile marine ecologists observed that lanternfish adjust vertical position based on thermal cues, optimizing feeding efficiency. Infrared detection allows them to focus on the most nutrient-rich patches, reducing wasted energy in sparse midwater environments. This sensory adaptation is particularly valuable during vertical migrations when light levels are extremely low. Infrared vision works in conjunction with lateral line detection to form a precise, multi-modal perception of the environment. Field studies indicate that lanternfish can detect temperature differences of just 0.002°C. This adaptation provides an advantage in energy conservation and predator avoidance. Lanternfish infrared sensitivity highlights the subtle but critical survival strategies of small deep-sea giants. It demonstrates how even tiny animals exploit advanced sensory adaptations for ecological success.
