What’s in ISSUE 21 / Colour & cold?


Alaska is wild, remote and home to myriad ocean species - including a particularly elusive one, the mysterious salmon shark.

THE GREAT giant cuttlefish aggregation

Every year, hundreds of thousands of giant cuttlefish aggregate in Australia's Spencer Gulf to mate. It is the largest event of its kind and one of nature's great spectacles.

The greatest whale show

For hundreds of humpback whales in the Gulf of Maine – along with up to 70 other species – life depends on one tiny fish: the sand lance.

Reef restoration

In Florida, Coral Restoration Foundation is tackling the seemingly impossible task of restoring an entire ecosystem, while also revealing what hurricanes, coral restoration and cameras have in common.

walking sharks and climate change

On the east coast of Australia, within the Great Barrier Reef, lives the world's only walking shark. The species might provide important answers on how sharks deal with climate change.
