What is the largest living mammal?

The largest living mammal is the blue whale (Balaenoptera musculus). These marine giants can grow up to 30 meters (98 feet) in length and weigh as much as 180 metric tons. Despite their massive size, blue whales feed primarily on tiny organisms like krill, which they filter through baleen plates in their mouths. Blue whales are found in oceans worldwide and are known for their incredible migrations across the seas. Their size and gentle nature make them one of the most awe-inspiring animals on Earth.
