Blue Whale: World's Largest Marine Mammal
The blue whale is the largest animal on Earth, reaching lengths of up to 100 feet and weights of around 200 tons. They are marine mammals, characterized by their massive size, long bodies, and blue-gray coloration. Blue whales are known for their deep, resonant vocalizations and are found in oceans worldwide, primarily in colder waters where they feed on krill. They are considered endangered due to factors like whaling and habitat degradation.
