Peter Symes has the story.

Each year, like clockwork, the great whales set out on journeys that boggle the imagination. Humpbacks swim from polar feeding grounds to tropical breeding lagoons and back again, a round trip that can span over 16,000 kilometres. Grey whales hug the coasts from Alaska to Mexico. Blue whales—the largest creatures ever to live—glide across entire oceans, navigating waters with no visible roads, no signposts and no GPS. Yet somehow, they never seem to get lost.

No secrets are more haunting than the wrecks of the ships lying hidden beneath that shining surface. Scattered across the seafloor are the remains of thousands of ships, some torn apart by storms, others claimed by war, piracy or sheer bad luck. And in the eternal silence of the deep, these wrecks take on an eerie life of their own.

Flickers, glows, pulses of eerie blue and green. Like stars scattered in the deep sea. Welcome to the world of bioluminescence, nature’s living light show.
