Lancetfish can initiate attacks based solely on detecting the heat emitted by prey, without relying on vision or movement cues.
Lancetfish, elongated mesopelagic predators, have infrared-sensitive regions in their eyes allowing precise targeting of smaller fish. Juvenile ichthyologists observed that strikes were initiated based on thermal cues rather than movement, demonstrating the critical role of infrared vision. This adaptation reduces wasted energy and increases predation success, especially in sparse food environments. Infrared detection complements lateral line systems, enabling lancetfish to judge distance and speed accurately. Field studies reveal that even prey partially camouflaged against the water column can be detected via heat signatures. The adaptation also assists in predator avoidance by sensing warm-bodied threats in advance. Infrared vision has evolved to maximize survival in the low-light, high-pressure midwater zones. It represents a remarkable example of convergent evolution among deep-sea predators. Lancetfish infrared capabilities underline the importance of sensory specialization in extreme environments.
