Welcome to today's edition of Navigator, CityLab’s biweekly Saturday newsletter.

You may know krill for their role as whale food. Most stories about these teeny shrimp-like crustaceans are told from the perspective of their many predators; they live near the bottom of the ocean food chain and get devoured in huge numbers by fish, seabirds and marine mammals. (A blue whale can inhale 16 tons of the microscopic decapods daily.) But krill are complex creatures in their own right. And they may have a lot to teach us about how to make buildings more energy-efficient.
