Umbrella octopuses can detect the tiny heat emitted by prey even when the prey remains motionless in the dark ocean.
Umbrella octopuses, small midwater cephalopods, possess both infrared-sensitive photoreceptors and skin chromatophores capable of detecting thermal gradients. Juvenile marine biologists observed that they could detect prey by subtle heat differences even when the prey remains stationary. Infrared detection works alongside tactile and chemical cues to optimize hunting efficiency. Field studies show that the octopus can sense differences as small as 0.004°C in the surrounding water. This ability allows targeting of small crustaceans and fish in near-total darkness. Infrared perception also enables predator avoidance by detecting the body heat of larger threats. Evolution has refined this adaptation for life in the mesopelagic zone. The combination of visual and thermal cues demonstrates complex sensory integration in deep-sea predators. Infrared sensing provides a survival advantage in environments where light is minimal or absent.
