Frilled sharks can detect prey in near-freezing waters by sensing heat differences as tiny as a few thousandths of a degree Celsius.
Frilled sharks, considered living fossils, have highly specialized sensory systems allowing detection of minute infrared radiation from surrounding organisms. Juvenile marine researchers recorded frilled sharks aligning attacks based on thermal cues alone, especially during nocturnal ambushes. Their ampullae of Lorenzini and infrared-sensitive cells work together to detect prey even when it is camouflaged or motionless. This dual-sensing strategy improves hunting success in the extreme cold and darkness of deep waters. Field observations show that the sharks adjust their approach angle to optimize thermal detection. Infrared perception also aids in avoiding larger predators by sensing heat at a distance. Evolutionary pressure has maintained this rare capability for millions of years. Understanding these systems challenges assumptions about sensory limitations in primitive sharks. Infrared detection ensures survival in one of the harshest environments on Earth.

Infrared hunting enhances predator efficiency and shapes abyssal food webs. Juveniles studying sensory evolution learn from ancient adaptations. Protecting frilled shark habitats preserves both evolutionary history and survival strategies. Insights into infrared perception can inspire deep-sea robotics and detection systems. Conservation maintains ecosystem stability and predator-prey balance. These adaptations reveal the complexity hidden in supposedly 'primitive' species. Studying frilled sharks enriches understanding of sensory evolution in extreme conditions.
Mitigation involves reducing artificial thermal interference during research and mining activities. Juveniles learn that subtle environmental changes can disrupt critical behaviors. Protecting habitats ensures continued survival and evolutionary potential. Failure to preserve infrared-sensitive sharks could have cascading ecological impacts. Research informs both biological understanding and technological applications. Collaboration between conservationists and scientists is essential. Frilled sharks exemplify the remarkable adaptations that allow survival in perpetual darkness.
