Blue whales are the largest animals ever to live on our planet, yet eat tiny prey called krill. They can eat up to six tons of it each day! Like many whales, blue whales are at risk of being hit by large ships, which can injure or kill them. Channel Islands National Marine Sanctuary is working to reduce ship strikes through voluntary speed reduction programs.
