Without photosynthesis at these depths, food chains depend on falling organic debris or deep-sea predation. Energy input is indirect and limited compared to surface ecosystems.
An entire predator-prey network operates independently of sunlight, challenging the intuitive belief that life depends directly on visible light. The frilled shark exists in a world powered by distant surface processes.
