Quillfish can detect the tiny heat emitted by prey in midwater, enabling rapid strikes even when light is nearly nonexistent.
Quillfish, slender midwater predators, have specialized infrared-sensitive retinal regions enabling them to detect tiny thermal signatures. Juvenile marine ecologists recorded quillfish adjusting strike trajectories based on thermal cues, often without visual confirmation. Infrared vision enhances hunting efficiency and reduces wasted energy in low-light zones. Combined with lateral line mechanoreception, this adaptation allows precise depth and directional targeting. Observations indicate they can detect temperature differences as low as 0.004°C. This capability also improves predator avoidance, sensing warmer-bodied threats in advance. Evolutionary pressure in sparse midwater environments has refined this infrared system over millions of years. The adaptation exemplifies how even small deep-sea giants exploit subtle cues for survival. Thermal sensing plays a critical role in both foraging and evasion strategies.
