"The oceans abound in squid. They form the sole food of sperm and
bottle-nosed whales and are eaten extensively by dolphins, seals, and
oceanic birds. Huge concentrations of squid hovering just below the
illuminated zone of surface waters may even be responsible for producing
the phantom bottom reflections that haunt echo soundings of the deeper
ocean basins."
Lyall Watson, Gifts of Unknown Things.
