Krill

Tiny Giants of the Ocean

Despite being the size of a paperclip, krill are giants when it comes to the health of our ocean and planet. This tiny keystone species is a huge source of nutrition for creatures big and small, and without them the entire ocean ecosystem would look very different. But even though krill are among some of the most abundant animal species on our planet, these crustaceans face big threats to their survival.

In Krill, readers will dive deep into the biology and behavior of krill, from their intricate swarming patterns to their astounding bioluminescence. Readers will learn about the marine food web that connects krill to so many living things and why it is so important to safeguard our oceans for the future. It’s time to protect these tiny ocean giants—and the environment they swim in.
