Colossal squids’ eyes are so large they can detect the faint heat emitted by a fish several meters away in total darkness.
Colossal squids possess eyes up to 27 centimeters wide, adapted not only for low-light vision but also for infrared detection. Juvenile marine scientists recorded instances where squids oriented toward prey solely based on thermal cues in near-complete darkness. Specialized retinal cells respond to infrared wavelengths, allowing them to detect body heat from fish and smaller squid. This infrared capability complements their enormous eyes, increasing hunting efficiency in the deep ocean. Studies show that infrared detection helps squids conserve energy by focusing only on viable prey. The adaptation also aids in predator avoidance, sensing approaching sperm whales or other large predators before they are visible. Researchers note that this dual sensory system is unparalleled among cephalopods. It underscores the sophisticated evolutionary solutions developed for survival in extreme environments. Infrared perception in colossal squids reveals that even in total darkness, life can effectively 'see' heat.
