Feature: Hide & Seek
Whale sharks may be the largest fish in the ocean but they are particularly elusive. Researchers are now using photographic and genetic methods to find out their migration patterns and determine the best conservation strategies to protect them from threats posed by shipping accidents and unregulated fishing.

Expert Opinion: The Persistent Killer of Killer Whales
Killer whales are at risk due to PCB contamination despite a near-global ban more than 30 years ago. The threat affects more than half of the world’s orcas, and whale populations near industrialised regions and at the top of the food-chain are at a high risk of population collapse over the next 100 years.
