The Tale of Two Skates: How a Genetic Twist Solved a Century-Old Mystery

An illustration of the (A) pre-whaling and (B) post-whaling interactions between whales, shrimp-like krill (pink), and photosynthesizing organisms known as phytoplankton (top left of each panel) in the Southern Ocean. The decimation of whales in this ecosystem and coincident drop in krill in some former whaling grounds implies a large shift in the amount of iron available due to the loss of whales and thus micronutrients in whale poop (lower left).
