What is the largest animal currently on Earth?

The Blue Whale is currently the largest animal on Earth. It can reach lengths of up to 98 feet and weigh over 200 tons. Its massive size is a result of its evolutionary adaptation to life in the ocean, allowing it to efficiently gather and process large quantities of tiny shrimp-like animals known as krill. The Blue Whale's size provides it with numerous advantages, including the ability to access vast food sources and maintain its internal body temperature in cold ocean waters.
