Blue whales are filter feeders, meaning they eat small organisms like krill and plankton by filtering them out of the water. They can consume up to 4 tons of food per day. Blue whales are also very social animals and often travel in pods of up to 100 individuals. They communicate with each other using a series of low-frequency sounds that can travel for hundreds of miles.

Blue whales are an endangered species and their population is estimated to be around 10,000 individuals. The main threats to blue whales are hunting, ship strikes, and pollution.
