Editor’s Note

This year’s marine issue is here to make a splash. Dive deep into the ecology and social culture of killer whales, and learn why this research matters for conservation. Next, climb aboard the research ship Oscar Elton Sette in the western Pacific Ocean and experience firsthand a day in the life of a bioacoustician tracking false killer whales (a species of oceanic dolphin). Then, head to the opposite end—the Eastern Tropical Pacific Ocean—where the governments of Costa Rica, Panama, Ecuador, and Colombia have committed to protecting ‘swimways’ that connect different marine protected areas, and which are used by countless migratory species (including the critically endangered scalloped hammerhead shark).

Take a break to sip on hot chocolate made using a secret 18th century recipe containing ambergris (‘whale vomit’)—a mysterious substance with a history spanning centuries, continents, and cultures. Thus refreshed, you can once again dive underwater to witness human-made reefs, which are creating new spaces where people and marine life mingle.

Next, puzzle over why the central desert of Baja California in northwestern Mexico features in a marine-themed issue. And don’t be surprised when you learn that South Africa not only has penguins, but that their conservation is “everyone’s business”. Finally, you are invited to attend the Shockington Conservation Awards, where our notorious columnist celebrates the great achievements of conservation and the “hardworking people who labour so tirelessly” for the cause. Just remember to bring your sense of humour along.
